The immature forms of animals which they are before metamorphosis are the larva.

Explanation:

The larva in plural form is known as the larvae. The eggs are hatch into the form of larva. These larvae grow in different stages which are marked according to the stages as I or II and so on.

After the larval development, when they are ready to be converted into adults, metamorphosis occurs. This process changes the larva into adults. Here the immature form gets converted into mature adult form.

Answer:

Explanation:

Ionic bonds are formed between atoms of metals and nonmetals, resulting in the transfer of electrons from the metal to the nonmetal, creating a stable crystalline compound with zero net charge.

Atoms from metals and nonmetals would form ionic bonds. Ionic bonds are electrostatic attractions between positively charged ions, or cations, and negatively charged ions, or anions. These attractions lead to the formation of a crystalline lattice in which the compound has a zero net charge. For example, sodium (Na), a metal, will donate its valence electron to chlorine (Cl), a nonmetal, leading to the formation of Na+ and Cl- ions. These ions will then attract each other, forming NaCl, also known as table salt, which exhibits a stable crystalline structure.

Another example is the formation of magnesium oxide (MgO) when magnesium (Mg), a metal with two valence electrons, reacts with oxygen (O2), a nonmetal with six valence electrons. Magnesium will lose two electrons to become Mg2+, while oxygen will gain those electrons to become O2-. The resulting compound is an arrangement of oppositely charged ions held together by the force of their attraction, resulting in MgO's stable ionic crystalline structure.

Answer:

You will need 7.953 kJ heat energy to raise the temperature of water from 277K to 315K.

Explanation:

To calculate how much heat is needed to raise the temperature of any substance, you need:

The mass of the substance,  m, which for you is 50.0 g

The temperature change that occurs,  ΔT, which for you is:

Δ[tex]T=(315-277)K=38K[/tex]

The specific heat capacity of the substance,  c,

For water, the value of  c  is  4.186J/gK

Then, this is the equation you need:

[tex]Q=mc[/tex]ΔT

Where Q is the heat needed

So,  

[tex]Q=(50.0g)(4.186J/gK)(38K)=7953.4J=7.9534kJ[/tex]

You need 7.953 kJ to raise the temperature of water from 277K to 315K.

The heat required to raise the temperature of 50.0 g of water from 277 K to 315 K is 7964 joules, using the specific heat capacity of water, which is 4.18 J/g°C and the formula Q = mcΔT.

To calculate the amount of heat required to raise the temperature of water, we use the specific heat capacity of water, which is 4.18 J/g°C. The formula we'll use is Q = mcΔT, where Q is the heat energy, m is the mass of the water, c is the specific heat capacity, and ΔT is the change in temperature.

For 50.0 g of water being heated from 277 K to 315 K, the change in temperature (ΔT) is (315 K - 277 K) = 38 K. Since the Kelvin and Celsius scales are offset by a constant but rise at the same rate, an increase of 1 K is equivalent to an increase of 1 °C. Therefore, the heat energy required can be calculated as follows:

Q = mcΔT
Q = (50.0 g) × (4.18 J/g°C) × (38 °C)
Q = 7964 J

Therefore, 7964 joules of heat energy is needed to raise the temperature of 50.0 g of water from 277 K to 315 K.

The kinetic energy of an 80kg object moving at a velocity of 4m/s is 640 Joules. This can be calculated using the formula for kinetic energy, which is K = 0.5 × m × v².

The kinetic energy of an object can be calculated using the formula K = 0.5 × m × v², where 'K' is the kinetic energy, 'm' is the mass of the object, and 'v' is the velocity of the object. Substituting the provided values into the formula, we have K = 0.5 × 80kg × (4m/s)² = 0.5 × 80kg × 16m²/s² = 640 Joules. Therefore, the kinetic energy of the object is 640 Joules.

d, its act only ob material that are touching a magnet

The false statement about magnetic force is: it act only on materials that are touching a magnet.​ Hence, option (d) is correct.

Electromagnetic force is a result of charge motion, which also produces magnetic force. We know that a moving charge creates a magnetic field around itself. In this situation, the magnetic force can be thought of as a force that results from magnetic fields interacting.

As magnetic force is a field force, it  is expected over a distance. In every atoms, electron revolves around nucleus but a certain type of material has non-zero net magnetic momentum. Magnetic field affects only the material with non-zero net magnetic momentum. Same poles of magnets repulse whereas opposite poles of magnets attract. But due to being a field force, it  does not act only on materials that are touching a magnet - it acts all material in its surroundings .​Hence, option (d) is correct.

Answer:

telescope

Explanation:

Answer:

Astronomical telescope

Explanation:

A telescope is a device used to observe object that are at distant places. It is comprised of lens or mirrors (convex or concave). Light is allowed to pass through it , producing a reflected or a refracted image. The magnification of an image is directly proportional to the len's or mirror's size. A bigger lens produces a magnified and clear image as it allows more amount of light to enter the lens, whereas a smaller lens will produce a smaller image due to its smaller amount of incident light.

Thus, an astronomical telescope is a tool extensively used to view the outer space.

The correct path of sperm cells through the male reproductive system is seminiferous tubules, epididymis, vas deferens, and then the urethra.

The correct path of sperm cells through the male reproductive system is from the seminiferous tubules, where they are formed, to the epididymis, where they mature and are stored. From there, during ejaculation, the sperm move through the vas deferens, which is part of the spermatic cord, towards the ejaculatory duct. Finally, the sperm cells travel through the urethra and are expelled from the body. Thus, the complete path is: Seminiferous tubules, Epididymis, Vas deferens, Urethra.

The terrestrial planets are small, and their composition is different than that of the jovian planets. The terrestrial planets have a solid iron inner core, liquid iron outer core, silicate mantle, and silicate crust. The jovian planets are also called gas giants because they are much larger and are gassy, not hard as the terrestrial planets. These planets have a silicate inner core, ice outer core, liquid metallic hydrogen layer, liquid hydrogen layer, and on the top gaseous hydrogen.

Answer:

Answer:

D) The heavier ball will have a higher temperature because the change of temperature is inversely proportional to mass.

Explanation:

As stated in the problem, the amount of heat released by each ball is

[tex]Q=mC_p \Delta T[/tex]

where

m is the mass of the ball

Cp is the specific heat of iron (so, it is equal for both balls)

[tex]\Delta T[/tex] is the change in temperature of each ball

In this problem, we are said that the amount of heat released by the two balls, Q, is the same. Cp is also the same: this means that the product [tex]m\Delta T[/tex] must be the same for the two balls. So, the mass and the change in temperature are inversely proportional: therefore, the heavier ball will have a smaller change in temperature. And since both balls starts from the same temperature, 100 C, this means that the heavier ball will reach a higher temperature than the lighter ball.

Final answer:

The image formed by a plane mirror is virtual, upright, and of the same size as the object.

Explanation:

The image formed by a plane mirror exhibits specific characteristics. First and foremost, the image is virtual, meaning it cannot be projected onto a screen because it appears to be behind the mirror. The image is also upright, which means it has the same orientation as the actual object (it is not inverted). Moreover, the image is of the same size as the object, which differentiates it from images formed by curved mirrors that can be either magnified or diminished.

Answer:

Explanation:

Well you have the voltages right, and that is no trivial matter. Each one of the resistors in a parallel circuit sees the same input voltages (in this case 6).

Now I think it would be a good idea to fill in the the resistance column.

R1 = 3 ohms

R2 = 6 ohms

R3 = 2 ohms

The total resistance can be calculated in two ways. I'll get around to doing both of them but I'll do the conventional way first. One hint: the total resistance must be smaller than the smallest resistor. Read that sentence over a couple of times. What it means is that it must be less than 2 ohms in a parallel circuit.

1/r1 + 1/r2 + 1/r3 = 1/rt

1/3 + 1/6 + 1/2 = 1/rt

Change all the denominators to 6ths.

2/6 + 1/6 + 3/6 = 1/rt

(2 + 1 + 3)/6 = 6/6  = 1

rt = 1

====================

So the current I is V/R

V = 6

R = 1

Current = V/R = 6/1 = 6 amps.

====================

The current in each resistor is

I1 = V / R1

I1 = 6/3 = 2 amps

I2 = V/R2

I2 = 6/6 = 1 amp

I3 = 6/2 = 3 amps

The total is I1 + I2 + I3 = 2 + 1 + 3 = 6 amps.

======================

Remember I said there was 2 ways of figuring out the total resistance. I did one of them about. Here's the other.

R = V / It

R = 6 / 6

R = 1 ohm just what you got before.

====================

Power

P = V * I

P1 = 6 * 2 = 12 watts

P2 = 6*1   = 6 watts

P3 = 6*3 = 18 watts

Pt =            36 watts.

Pt can be done by using the voltage * the total current

Pt = 6 volts * 6 amps = 36 watts, just what you would expect.

Answer:

F = m × a

Explanation:

M= Mass

A= Acceleration

F= Force

Final answer:

The main formula for calculating force is F = ma, according to Newton's Second Law of Motion. For forces like gravity and tension, specific adaptations of this principle are applied. Other situations may use formulas derived from the basic principles, depending on the context, such as impulse or material properties.

Explanation:

The mathematical formula most commonly used to calculate force is derived from Newton's Second Law of Motion, which states that force is equal to mass times acceleration (F = ma). When calculating the force of gravity on a mass, the formula F = mg can be used, where 'g' represents the acceleration due to gravity. Additionally, when dealing with the force of tension, it must equal the force of gravity plus any force necessary to accelerate the mass. Note that for the calculation of normal force and tension force, if it is not given, Newton's 2nd Law should be applied.

Relativistic force considers force as the time derivative of momentum. The average force can also be computed using the concept of impulse, where average force equals the force time curve area divided by the time interval. Furthermore, when dealing with specific situations like the force on a cable, the force can be found using the formula F = (Y * A * ΔL) / L, where 'Y' is the Young's modulus of the material, 'A' is the cross-sectional area, 'ΔL' is the change in length, and 'L' is the original length.
