DedPeter [7]

Answer:

\Delta T=\frac{v_{i}^{2}}{4c}

Explanation:

Let the mass of bullet is m, initial velocity of bullet is vi and c be the specific heat of the bullet.

Kinetic energy, K = 1/2 mvi^2

According to the question, 50% of the kinetic energy is equal to the heat energy absorbed by the bullet.

50% of K = mass of bullet x specific heat x rise in temperature

1/4 mvi^2 = m x c x ΔT

\Delta T=\frac{v_{i}^{2}}{4c}

lys-0071 [83]
A. The IV is the temperature of gas in the balloon.

B. The DV is the volume of the balloon.

This is because the temperature of the gas is the variable being manipulated in the experiment (Independent) and the volume is changing based on the shifts of the temperature (thus volume is Dependent).

Explain the difference between speed and vilocity?
Zolol [24]

Answer:

The short answer is that velocity is the speed with a direction, while speed does not have a direction.

Explanation:

Speed is how fast an object is moving. It is calculated by the displacement of space per a unit of time. Velocity is the rate at which an object changes position in a certain direction. It is calculated by the displacement of space per a unit of time in a certain direction. Velocity deals with direction, while speed does not.
