Answer:Water

Explanation:

The 100g of water cooling from 100°C to 50°C releases more energy (5000 cal) compared to the 100g of iron cooling from the same temperature (535 cal). This is determined by the concept of specific heat capacity.

To determine which releases more energy, we'll need to consider the concept of specific heat capacity, a property that depends solely on the type of substance absorbing or releasing heat. This is what will be crucial in deciding whether the 100g of water cooling from 100C to 50C or the 100g of iron cooling from 100C to 50C releases more energy. The specific heat capacity of water is around 1.00 cal/g °C, while the specific heat of iron is found to be about 0.449 J/g °C, as per given statements.

Calculating the heat or energy (q) lost in the cooling process is given by the formula q=mcΔT, where m stands for mass, c represents specific heat capacity, and ΔT is the temperature change. For water, we have q = (100g)(1 cal/g °C)(50°C) = 5000 cal. For iron, we need to first convert the specific heat capacity to cal/g °C (1 J = 0.239 cal), giving us ~0.107 cal/g °C. So, q = (100g)(0.107 cal/g °C)(50°C) = 535 cal for iron.

As evident, the 100 grams of water cooling from 100°C to 50°C releases more energy (5000 cal) than the 100 grams of iron undergoing the same temperature change (535 cal).

by changing the frequency of standing waves

Musical instruments vary pitch by changing the frequency of standing waves.

Answer:

14 m/s

Explanation:

The motion of the book is a free fall motion, so it is an uniformly accelerated motion with constant acceleration g=9.8 m/s^2 towards the ground. Therefore we can find the final velocity by using the equation:

[tex]v^2 = u^2 + 2gd[/tex]

where

u = 0 is the initial speed

g = 9.8 m/s^2 is the acceleration

d = 10.0 m is the distance covered by the book

Substituting data, we find

[tex]v=\sqrt{0^2 + 2(9.8 m/s^2)(10.0 m)}=14 m/s[/tex]

Answer:

The dead spot experienced was due to the effect of sound wave interference

Explanation:

Sound wave interference occurs when wave interact. They can interact constructive manner increasing each other's strength and rising the intensity of the final wave produced.The waves can also interact destructively reducing each other's strength and intensity.In some cases, destructive interaction causes a total cancelling of the waves resulting to places where no sound can be heard at all.This area is the dead spot.

Answer:

the answer is Mesosphere

Explanation:

Answer:

0.03 s

Explanation:

The maximum force is 90 N, and the mass is 0.2 kg, so we can find the deceleration:

F = ma

-90 N = (0.2 kg) a

a = -450 m/s²

The initial velocity is 14 m/s, and the final velocity is 0 m/s, so the time is:

v = at + v₀

0 m/s = (-450 m/s²) t + 14 m/s

t = 0.03 s

The fastest she can slow it down to a stop without breaking it is in 0.03 s.

Answer:

c = 0.6 J/g°C

Explanation:

Heat is given by the formula;

Heat = mass× specific heat capacity × change in temperature

Mass = 455 g

Heat = 1638 J

ΔT = 6 °C

Therefore;

1638 J = 455 g× c × 6

c = 1638/(455×6)

c = 0.6 J/g°C

Covalent bonds hold non-metallic atoms together. These atoms have many electrons in their outermost level and have a tendency to gain electrons rather than to yield them.  

In this case the bond is formed by sharing a pair of electrons between the two atoms, one from each atom. Then, this pair of shared electrons is common to the two atoms and holds them together, so that both atoms acquire more stability.

Therefore the correct answer is C.

Answer:

A. Shorter in wavelength and higher in energy

Explanation:

The peak wavelength of a star can be found by using Wien's displacement law:

[tex]\lambda=\frac{b}{T}[/tex]

where

b is the Wien's displacement constant

T is the surface temperature of the star

From the equation, we see that the peak wavelength [tex]\lambda[/tex] is inversely proportional to the temperature: therefore, a star which is hotter then the sun (greater T) will have shorter wavelength.

Moreover, the energy of the emitted radiation is inversely proportional to the wavelength:

[tex]E=\frac{hc}{\lambda}[/tex]

where h is the Planck constant, c is the speed of light. Therefore, shorter wavelength means higher energy.

So, the correct answer is

A. Shorter in wavelength and higher in energy

Answer:

The answer is A. shorter in wavelength and higher in energy

In terms of the scientific definition of work, magnetic fields can do work, but electric fields cannot:

False

Answer:

FALSE

Explanation:

As we know that magnetic force is given by

[tex]\vec F = q(\vec v \times \vec B)[/tex]

so here magnetic force is always perpendicular to the velocity of the moving charge

so here we can say

[tex]\vec F . \vec v = 0[/tex]

so here since it is not producing any power so here rate of work done is zero which means it will not do any work

while in electrostatic force we know that

F = qE

so here force is not perpendicular to displacement or velocity so it will do work

Explanation:

The gravitational potential energy of an object is given by

[tex]U=mgh[/tex]

where

m is the mass

g is the gravitational acceleration

h is the heigth of the object relative to some reference point (for instance, the ground)

As we see from the formula, the gravitational potential energy is directly proportional to the mass, m: therefore, if the mass of the cylinder is increased by a factor 3, then the gravitational potential energy will also increase by a factor 3.

Answer:

It increased by a factor of 2.

Explanation:

Answer:

The intensity increases by a factor 9

Explanation:

The intensity of a sound wave follows an inverse square law, that means that it is inversely proportional to the square of the distance:

[tex]I\propto \frac{1}{r^2}[/tex]

where r is the distance from the source.

In this problem, the distance from the source is reduced by a factor 3, so the new distance is

[tex]r'=\frac{1}{3}r[/tex]

this means that the new intensity will be

[tex]I' \propto \frac{1}{r'^2}=\frac{1}{(\frac{1}{3}r)^2}=9\frac{1}{r^2}=9I[/tex]

So, the intensity will increase by a factor 9.

Answer:

The intensity increases by a factor of 9

#SPJ2

Answer:

A ball moving until gravity pulls it back down to the ground

Explanation:

One example of Newton's first law is a crash test dummy moving forward during a sudden stop due to inertia. Another is a spinning top maintaining its motion without external forces like friction. Finally, a block would keep sliding on a table at constant velocity without friction, illustrating this law.

One example of Newton's first law, also known as the law of inertia, can be seen in a car crash test. Imagine a crash test where a car abruptly stops upon hitting a barrier. The crash dummy inside continues to move forward at the same speed and in the same direction as the car was traveling before the collision. This is because there is no external force acting on the dummy's body to change its state of motion, thus it keeps moving due to inertia, as stated by Newton's first law.

Another illustration is the behavior of a spinning top. A top will continue to spin at a constant speed in the absence of external forces such as friction. Once friction is introduced, it acts as an external force that gradually slows down the spinning top, demonstrating that without such forces, the object would maintain its motion indefinitely.

Finally, consider a block sliding on a table. The block will eventually come to a stop not because it naturally prefers to be at rest, but because of the force of friction acting between the block and the table. Without this friction or any other external force, the block would continue to slide at a constant velocity in a straight line as described by Newton's first law.

Answer:

In the Newton's first law of motion, a stationary body or that moving with uniform motion will only chnage its state if acted upon by other forces externally.This kind of resistance is caused by the force of inertia.In his second law of motion,when a body is acted by a force, the force will be equal to the product of mass and acceleration of the body.i.e F=ma. In the third law of motion, it explains that a body will exert an equal and opposite force when interacting with another body.Thus, every action force experiences an equal and opposite reaction force.Here the momentum of the bodies will be conserved.

Answer:

There are two main factors that makeocean water more or less dense than about 1027 kg/m3: the temperature of the water and the salinity of the water.Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases thedensity of sea water.

Final answer:

The density of water in deep currents is determined by its temperature and salinity, with colder temperatures and higher salinity leading to denser water, which drives the thermohaline circulation.

Explanation:

The density of water in deep currents is determined primarily by two factors: temperature and salinity. As the temperature of water decreases, its density increases, which is often the case near the polar regions where the water is colder. Similarly, when the salinity of water increases, its density also increases, because the dissolved salts add to the mass of the water without significantly increasing its volume.

These changes in density are crucial for thermohaline circulation, the global pattern of deep currents that move throughout the oceans. Cold, high-salinity water becomes heavy enough to sink to the ocean's bottom in polar regions, setting deep currents into motion. As this dense water moves, it mixes with less dense water, contributing to a global circulation that plays a key role in regulating Earth's climate.

According to the law of conservation of mass, in a chemical reaction, the mass of the reactants is equal to the mass of the product; matter cannot be created or destroyed.

When two substances react chemically to produce a new substance, the law of conservation of mass states that the mass of the reactants (the substances that are reacting) equals the mass of the product (the new substance formed). In other words, the total mass of the substances before the reaction is equal to the total mass after the reaction has occurred. This principle was established through careful quantitative analysis of chemical reactions in the 1790s, and it is a fundamental concept in chemistry that indicates matter cannot be created or destroyed in a chemical reaction; it can only change forms.

Answer:

1. The lowest stratum of the atmosphere

troposphere

2. Most of the earth's ozone is located in the  

stratosphere

3. Earth coldest temperature occur in the  

mesosphere

Explanation:

1: Troposphere

The troposphere is the lowest layer of the Earth's atmosphere. The air is very well mixed and the temperature decreases with altitude. Air in the troposphere is heated from the ground up. The surface of the Earth absorbs energy and heats up faster than the air does.

2: Stratosphere

Ozone is mainly found in two regions of the Earth's atmosphere. Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). This region of the atmosphere is called the stratosphere.

3: Stratosphere

As the mesosphere extends upward above the stratosphere, temperatures decrease. The coldest parts of our atmosphere are located in this layer and can reach –90°C. In the forth layer from Earth's surface, the thermosphere, the air is thin, meaning that there are far fewer air molecules.

Answer:

C.when the nucleus decays

Explanation:

In chemical reactions, the outermost electrons of atoms are re-arranged somehow without the involvement of the nuclei of the participating atoms of the elements.

Nuclear reactions causes changes within the atomic nucleus. For every atomic nucleus, a specific neutron/proton ratio ensures stability. When the stability ratio differs an atom becomes unstable and splits into one or more other nuclei with the emission of small particles of matter. This is what radioactivity entails.

Radioactive decay occurs when the unstable nucleus of an atom loses energy by emitting radiation, transforming it into a different, more stable element. Option C, when the nucleus decays, is the correct answer.

Radioactive decay occurs when an unstable atomic nucleus loses energy by emitting particles or electromagnetic waves. Among the given options, C. when the nucleus decays, is correct. This decay leads to the creation of different elements, as the original atom changes its atomic number. Alpha decay, beta decay, and gamma decay are some of the ways this process can occur. In alpha decay, an atom emits an alpha particle (two protons and two neutrons), which is equivalent to the nucleus of a helium atom. Through these decay processes, a radioactive isotope, or radioisotope, transforms into a more stable atom.
