What is meant by radioactive decay ?When an unstable atomic nucleus loses energy by radiation, the process is referred to as radioactive decay.
A substance is defined as radioactive if it has unstable nuclei. The three most common kinds of decay are alpha decay, beta decay, and gamma decay, all of which involve the emission of one or more particles.
The definition of alpha decay refers to a typical kind of radioactive decay when a nucleus generates an alpha particle.
A nucleus releases beta particles as it undergoes beta decay, a typical kind of radioactive decay.
A nucleus undergoes gamma decay when it transforms from a state with a greater energy to one with a lower energy by emitting electromagnetic radiation (photons).
Hence,
Gamma decay would be most likely deflected.

Answer:
the answer is C on edge.
Explanation:
Describe how electric potential energy, kinetic energy, and work change when two charges of opposite sign are placed near each other.
potential energy is energy that is stored and kinetic energy is energy in motion and I believe that if you try to put them together it might not work potential energy would be a minus in the side for kinetic energy would be a plus sign
As opposites attract, Potential energy is pulled to Kinetic energy. The force from Kinetic energy is working on potential energy over a distance. This means the potential energy (q )started with is being converted into kinetic energy (Q). Potential energy is accelerating and picking up speed.
What are potential energy and kinetic energy?Potential energy is what we call stored energy. Kinetic energy is a form of energy that an object or a particle has by reason of its motion.When the electric field does positive work on a charge (as in the example above), the potential energy of the field decreases as the tank is depleted of energy. Conversely, the potential energy increases when the electric field steals energy by doing negative work (by slowing down a charge, for instance).To learn more about potential and kinetic energies, refer to: https://brainly.com/question/18556454

Find the de broglie wavelength of an electron in the ground state of the hydrogen atom.
de Broglie wavelength (λ) is given by the equation
λ = h/p
where h=Planck’s constant whose value is 6.62 x 10^(−34) joule-seconds and
p = momentum of the particle(here electron)
In terms of kinetic energy(E) momentum(p) can be written as,
p=(2mE)^1/2
where m=mass of the particle.
Hence λ becomes
1 λ = h(2mE)^-1/2
Given here, E = 13.6 eV = 13.6×1.6×10^-19 joule
m(mass of electron)= 9.1×10^-31 kg
Putting these values in equation (1) we get ,
λ =0.332×10^(-9) meter
=3.32×10^(-10) meter
=3.32 Å
De Broglie wavelength of an electron in the ground state of the hydrogen atom is about 3.33 × 10⁻¹⁰ m

Further explanationThe term of package of electromagnetic wave radiation energy was first introduced by Max Planck. He termed it with photons with the magnitude is :
[tex]\large {\boxed {E = h \times f}}[/tex]
where:
E = Energi of A Photon ( Joule )
h = Planck's Constant ( 6.63 × 10⁻³⁴ Js )
f = Frequency of Eletromagnetic Wave ( Hz )
[tex]\texttt{ }[/tex]
Let's recall De Broglie's Wavelength Formula as follows:
[tex]\boxed{\lambda = \frac{h}{mv}}[/tex]
where:
λ = wavelength ( m )
h = Planck's Constant ( 6.63 × 10⁻³⁴ Js )
m = mass of object ( kg )
v = velocity of object ( m/s )
Let us now tackle the problem !

Given:
energy of the ground state of the hydrogem atom = E = 13.6 eV = 2.176 × 10⁻¹⁸ J
Asked:
wavelength of electron = λ = ?
Solution:
Firstly , we will calculate the speed of the electron :
[tex]E = E_k[/tex]
[tex]E = \frac{1}{2}mv^2[/tex]
[tex]v^2 = 2E \div m[/tex]

The color of an opaque object is the same as the light that is
a) transmitted b) absorbed c) reflected d) all of these
Answer: reflected
A material is opaque when it does not allow light to pass through itself.
In other words:
When light illuminates an opaque object, no ray passes through it, as most of the light is reflected or absorbed by the object.
In this context, the main characteristic of this type of objects is that the color of the material depends on the light it absorbs. It means that depending on its chemical composition they can absorb certain wavelengths (colors) and reflect others.
Therefore, the color we see in an object is the light it reflects. For example, if we see a red table, this means that when light iluminates it, this table absorbed all the visible wavelengths, except the red, which is the light that is reflected and perceived by our eyes.
Which example best illustrates the transfer of energy between two waves? A) A buoy rises in the water as a boat speeds past. B) A basketball rebounds from the backboard during a missed shot. C) An egg that rolls off the counter falls and breaks on the floor. D) A car that rear ends another car causes damage to both vehicles.
Answer:
A.
Explanation:
Answer: Option A
Explanation: Waves (mechanical and electromagnetic) can transfer energy when they impact into something.
When a boat speeds in the water, the boat itself pushes water around it generating mechanical waves in the water, those mechanical waves now travel on the surface of the water. When those mechanical waves impact the buoy, the waves also move the buoy, and now the buy is in a "wave-like" motion (you can model the movement of the buoy as a mechanical wave, that goes up and down), so this is a good example of energy transfer.
distinguish the differences between diamagnetic and paramagnetic materials. Give examples of each type of material
Answer:
Paramagnetic materials are attracted by external magnetic fields whereas diamagnetic materials are repelled. Paramagnetic materials have at least one unpaired electron in the system, but diamagnetic materials have all their electrons paired.
Explanation:
Diamagnetic materials are weakly repelled by magnetic fields due to induced dipoles aligning oppositely, while paramagnetic materials are weakly attracted due to their unpaired electrons aligning with the field. Copper and gold are examples of diamagnetic materials, whereas aluminum and magnesium are examples of paramagnetic materials.
Diamagnetic and paramagnetic materials respond differently to magnetic fields due to their distinct atomic properties.
Diamagnetism is characterized by a weak repulsion from magnetic fields. This occurs because the atoms in diamagnetic materials have no permanent magnetic dipole moments. When an external magnetic field is applied, it induces magnetic dipoles within the atoms. These induced dipoles align oppositely to the applied field, creating a repulsive effect. When the field is removed, the induced magnetic effect vanishes.
Examples of diamagnetic materials include copper, gold, and silicon.
Paramagnetism involves a weak attraction to magnetic fields. The atoms in paramagnetic materials have unpaired electrons, which results in permanent magnetic dipole moments. When an external magnetic field is applied, these dipoles tend to align with the field, enhancing its effect. However, this alignment is temporary and disappears when the external field is removed.
Examples of paramagnetic materials include aluminum, magnesium, and platinum.
An atom with an imbalance of electrons to protons is
An ion is an atom that is electrically charged by gaining or losing one or more electrons.
To understand it better:
An atom has a nucleus with electrons around it and has a neutral charge. When an electron is added or detached, this atom is electrically charged, that is, it ceases to have a neutral charge and becomes an ion.
In this sense, there are two types of ions:
-Anions: ions negatively charged, by the gain of electrons in the atom.
-Cations: ions positively charged, by the loss of electrons in the atom.
Final answer:
An atom that has an unequal number of electrons and protons is called an ion. This imbalance creates an ion with a net positive or negative charge, called a cation or an anion respectively.
Explanation:
An atom with an imbalance of electrons to protons is known as an ion. Atoms are normally electrically neutral because they have an equal number of protons and electrons. However, when atoms gain or lose electrons, they become ions, which can be either positively or negatively charged. This imbalance in charge leads to electrical forces that can cause the ion to interact with other ions or molecules.
A positive ion, called a cation, is formed when an atom loses one or more electrons. Conversely, a negative ion, referred to as an anion, is created when an atom gains electrons. The process of an atom becoming an ion is called ionization, and these ions play a crucial role in chemical reactions and the formation of compounds.

An electric light is plugged into a 120-V outlet. If the current in the bulb is 0.50 A, how much electrical energy does the bulb use in 15 minutes?
Answer:
= 54,000 Joules or 54 kJ
Explanation:
Electrical energy is given by the formula;
E = VIt; where V is the potential difference in volts, I is the current and t is the time in seconds.
Therefore;
Electrical energy = 120 V × 0.50 A × 15 ×60 seconds
= 54,000 Joules
Thus; the electrical energy is 54,000 joules or 54 kJ

A radioisotope has a half-life of 5.50 min and an initial decay rate of 7200 Bq. What will be the decay rate after 22 min? Show all work and include units of measure.
Explanation:
This problem can be solved using the Radioactive Half Life Formula:
[tex]A=A_{o}.2^{\frac{-t}{h}}[/tex] (1)
Where:
[tex]A[/tex] is the final amount of radioisotope (decay rate)
[tex]A_{o}=7200Bq[/tex] is the initial amount of the radioisotope
[tex]t=22min[/tex] is the time elapsed
[tex]h=5.50min[/tex] is the half life of the radioisotope
Knowing this, let's find [tex]A[/tex] from (1):
[tex]A=(7200Bq).2^{\frac{-22min}{5.50min}}[/tex] (2)
[tex]A=(7200Bq).2^{(-4)}[/tex]
[tex]A=(7200Bq)(0.0625)[/tex] (3)
Finally:
[tex]A=450 Bq[/tex]>>> This is the decay rate of the radioisotope
Note it is in Becquerels (Bq), which is the derived unit approved by the International System of Units for radioactivity

A neutral atom of tin (Z = 50) has 69 neutrons. (a) How many protons does it have? (b) What is its mass number?
Answer:
Protons = 50
Mass number = 119
Explanation:
A neutral of tin, Sn, has a Z value of 50 and neutrons are 69.
Z is the atomic number. The atomic number is equal to number of protons or number of electrons in an atom that is neutral i.e:
Z = PROTONS = ELECTRONS
So the number of protons = 50 since Z is 50
>>>>>>>>>>>>>>>¦
The bulk of the mass of an atom is concentrated in the nucleus. To calculate mass number, we simply sum all the elementary particles in the nucleus i.e protons and neutrons. These particles are called the nucleons.
Mass number (A) = P + N
= 50 + 69
= 119

An object is placed 9.5 cm in front of a convex spherical mirror. Its image forms 3.2 cm behind the mirror. What is the radius of curvature of the mirror? Show all work.
Using the mirror formula.
1/v + 1/u = 1/f
1/9.5 + 1/3.2 = 1/f
1/f = 3.2 + 9.5 / 9.5 * 3.2
1/f = 4.82 cm
Radius = 2f
Radius = 2 x 4.82
Radius = 9.64 cm
Answer:
Radius of curvature, R = 9.64 cm
Explanation:
It is given that,
Object distance, u = -9.5 cm
Image distance, v = 3.2 cm
We have to find the radius of curvature of the mirror. The relationship between focal length and the radius of curvature as R = 2 f where f is the focal length of the mirror.
Using Mirror's formulas as :
[tex]\dfrac{1}{v}+\dfrac{1}{u}=\dfrac{1}{f}[/tex]
[tex]\dfrac{1}{3.2}+\dfrac{1}{-9.5}=\dfrac{1}{f}[/tex]
f = 4.82 cm
And radius of curvature of the mirror becomes, R = 9.64 cm. Hence, this is the required solution.

A single slit diffraction pattern is formed on a distant screen. Assuming the angles involved are small, by what factor will the width of the central bright spot on the screen change if (a) the wavelength is doubled, (b)the slit width is doubled, or (c) the distance from the slit to the screen is doubled?
Final answer:
The width of the central bright spot in a single-slit diffraction pattern doubles if the wavelength or distance to the screen is doubled and halves if the slit width is doubled.
Explanation:
The width of the central bright spot in a single-slit diffraction pattern will change based on a few factors:
If the wavelength of the light is doubled, the width of the central bright spot will also double, since the width of the central maximum is directly proportional to the wavelength.
If the slit width is doubled, the width of the central bright spot will be halved, as the width of the central maximum is inversely proportional to the slit width.
If the distance from the slit to the screen is doubled, the width of the central bright spot will also double, due to similar triangles, where the pattern's size changes linearly with the distance to the screen.

Which of the following statements are true about bar magnets?
a. The direction of the magnetic field are considered to flow from the south pole to the north pole around the outside of the magnet.
b. If a bar magnet is cut in half, two new magnets will be formed each with a south and north pole
c. The north pole of a bar magnet will align itself with the South Pole of the earth.
d. All magnets have a similar magnetic field as a bar magnet.
Answer:
b. If a bar magnet is cut in half, two new magnets will be formed each with a south and north pole
Explanation:
As we know that magnetic field lines always originates from north pole of magnet and then terminate at south pole.
Also all magnets must have two poles (i) North pole (ii) South Pole
now if we break a magnet into two parts then this magnet will again form two new poles on the opposite sides so that each half will again have two different poles of magnet
So here we can say that when a bar magnet is cut into two parts then each part will behave like a new magnet.
so correct answer will be
b. If a bar magnet is cut in half, two new magnets will be formed each with a south and north pole
Final answer:
Bar magnets have a magnetic field direction from the north pole to the south pole externally, and cutting a bar magnet in half results in two new magnets each with a north and a south pole. The north pole of a magnet aligns with the Earth's magnetic South Pole.
Explanation:
The truth about bar magnets can be understood by examining their properties and behaviors:
Statement a is incorrect. The direction of the magnetic field lines around a magnet is from the north pole to the south pole externally, and it's the opposite inside the magnet.Statement b is correct. When you cut a bar magnet in half, you end up with two new magnets, each with a north and a south pole.Statement c is correct as the north pole of a bar magnet will align with the Earth's magnetic South Pole, which is geographically near the Earth's North Pole.Statement d is overly general. While it is true that all magnets have a north and south pole and the field lines form closed loops, their magnetic field shapes can vary based on the physical shape of the magnet.Compare the water pressure directly below the hull of the yacht (point

A) It has a temperature of about 3 degrees K above absolute zero. B) It is the result of a mixture of radiation from many independent sources, such as stars and galaxies. C) It had a much higher temperature in the past. D) It was discovered by Penzias and Wilson in the early 1960s. E) It appears essentially the same in all directions (it is isotropic)
Microwave background radiation was accidentally discovered by Penzias and Wilson on 1964. This is a form of electromagnetic radiation that is present in the whole universe and completely fills it (it is isotropic).
It is the leftover radiation from the big bang.Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.
It is important to note the Big Bang occurred 400,000 years before the events related to the microwave cosmic radiation, this means the Big Bang occurred first.
The incorrect statement about cosmic background radiation is that it's a mixture of radiation from many independent sources like stars and galaxies. It is actually the thermal radiation left over from the Big Bang.
Explanation:The statement B) It is the result of a mixture of radiation from many independent sources, such as stars and galaxies, is not true regarding cosmic background radiation. Cosmic background radiation is not a mixture of radiation from different sources, but actually the thermal radiation leftover from the 'Big Bang'. It's effectively the 'echo' or 'afterglow' of the Big Bang, and it appears essentially the same in all directions, which means it's isotropic.
It has a temperature of approximately 3 degrees Kelvin (just above Absolute Zero), as discovered by Arno Penzias and Robert Wilson in the early 1960s. This radiation was much hotter in the past, but has cooled as the universe expanded over billions of years.
