The item would have a terminal velocity of 19 m/s.

Using the formula below, you can determine an object's final velocity given its starting velocity, acceleration, and time interval:

Final speed (v) equals the starting speed (u) plus acceleration (a) multiplied by time (t).

We'll enter the values into the formula now:

The starting speed (u) is 4 m/s.

Acceleration (a) equals 3 m/s2

Time (t) equals five seconds.

Final velocity (v) = 4 m/s + 3 m/s2 * 5 s

How to figure out the equation's right-hand side:

(15 m/s) plus (4 m/s) is the final velocity (v).

The transfer of energy Q (microscopic work) from the surroundings into the block plus bullet system during the collision is equal to the rise in thermal energy of the system, which is 2313.375 J.

Collision is the physical contact of two or more objects. In physics, it is the act of two or more things coming into contact with each other. Collisions can be either elastic or inelastic, and can involve energy transfer or momentum transfer.

The kinetic energy of the bullet plus the block before the collision is equal to the kinetic energy of the bullet alone,
which is equal to \(0.5 \times 0.135 kg \times (150 m/s)^2 = 11.625 J.\)
The kinetic energy of the bullet plus the block after the collision is equal to the sum of the kinetic energies of the bullet and the block, which is equal to \(0.5 \times 0.135 kg \times (300 m/s)^2 + 0.5 \times 3.5 kg \times (300 m/s)^2 = 2325 J.\)

The rise in thermal energy of the bullet plus block as a result of the collision is equal to the difference between the kinetic energy of the system before and after the collision, which is 2325 J - 11.625 J = 2313.375 J.

Explanation:

The airplane has an acceleration of approximately 1.78 m/s².  The result demonstrates that the acceleration is influenced by the distance covered and the time taken.

To find the acceleration of the airplane during takeoff, we can use the equation of motion:

d = ut + (1/2)at²

where d is the distance, u is the initial velocity (which is 0 m/s since the airplane starts from rest), a is the acceleration, and t is the time.

We know that the distance covered is 800 meters and the time taken is 30 seconds, we can rearrange the equation to solve for acceleration:

a = 2(d - ut) / t²

Substituting the values, we have:

a = 2(800 m - 0 m/s * 30 s) / (30 s)²

Simplifying the equation, we get:

a = 2(800 m) / (900 s²)

a ≈ 1.78 m/s²

Therefore, the acceleration of the airplane during takeoff is approximately 1.78 m/s².

In conclusion, Using the equation of motion and the given values of distance and time, we calculated the acceleration of the airplane during takeoff. The result demonstrates that the acceleration is influenced by the distance covered and the time taken.

In this case, the airplane has an acceleration of approximately 1.78 m/s². Acceleration plays a crucial role in the takeoff process as it determines how quickly the airplane can gain speed and lift off from the runway.

Thermal energy is transferred between objects only when they have different temperatures.

The movement of atoms and molecules within a substance is a form of energy known as thermal energy.

When two objects are in contact, or even in proximity, the atoms and molecules in the hotter object collide with those in the colder object.

Because of these effects, a portion of the kinetic energy from the more sizzling object is moved to the colder object, raising the temperature of the previous and bringing down the temperature of the last option.

A material's thermal conductivity — an estimation of how well it moves heat — decides how rapidly heat is moved between various sorts of materials.

\(\boxed {\boxed {\sf a= -2 \ m/s^2}}\)

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

\(a=\frac{v_f-v_i}{t}\)

The final velocity of the cat was 0 meters per second and the initial velocity was 10 meters per second. The time was 5 seconds.

\(v_f=0 \ m/s\\v_i=10 \ m/s\\t= 5 \ s\)

Substitute the values into the formula.

\(a=\frac{0 \ m/s-10 \ m/s}{5 \ s}\)

Solve the numerator.

\(a=\frac{-10 \ m/s}{5 \ s}\)

Divide.

\(a= -2 \ m/s^2\)

The acceleration of the cat was -2 m/s². The negative acceleration indicates slowing down or stopping.

Answer:

Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.

Explanation:

Now What is light?

-Light ( or light energy ) is defined as a form of electromagnetic radiation and a type of kinetic energy.

-Light is made up of photons. Photons is the basic unit of light. They are produced when an object's atom is subjected to heat. The more the atoms are heated, the more photons are created.

-Light travels in the form of a wave but it does not require any medium for transmission.

-Light travels so fast, nothing is faster than it. It travels at a constant speed of 186,282 miles/sec ( 300,000 km/sec ) in vacuum and whether the source is moving or stationary.

-Light can be measured in either joules, calories ( energy units ), quanta and einsteins ( quantum units ). Conversion from one unit to another heavily depends on wavelength.

Now an unaided human eye can only see the visible light, namely red, orange, yellow green, blue, indigo and violet (Roy G Biv) but light also comes in other forms that we cannot see, they are named, radio wave, microwave, infrared, ultraviolet, x-ray and gamma ray.

Answer:

The same amount of wax exists before and after the change.

Explanation:

The melting of wax is a physical change and not a chemical change. During a physical change, no new substance is formed as chemical reactions do not take place. In a chemical change, however, new substances are formed because chemical reactions do take place.

In addition to that, both physical and chemical changes obey the law of conservation of matter which states that matter can neither be created nor destroyed but can be transformed from one form to another. It also entails that the mass of a substance present before a reaction should be equal to the mass obtained after the reaction.

In this case, the candle just simply changed its state from solid to liquid. This means that the total mass of the candle that existed as a solid will be the same as that of the liquid state.

Answer:

The answer is C). The same amount of wax exists before and after the change.

Explanation:

The reason for this is simple. If you put a block of wax in a pan, and put it on the scale, (lets say it weighs 2 pounds) it will way two pounds. If you stick it on a stove, and it melts, does it weigh the same amount? Yes, it does. This is because none of the wax left the pan. It just moved around. The only difference is that it is a liquid. It still has the same amount of wax.
