The answer is; A
As the ball bounces, the kinetic energy is lost as heat and therefore the initial energy of the ball reduces. The ball, therefore, bounces to a less height with each bounce. As the ball hits the floor, it deforms and reforms again. This compression and decompression including friction between the ball and floor are some of the contributors to the loss of its energy to heat (that also warms it up).
Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.
Answer:
P = 6.63 kW
Explanation:
Given that,
Current, I = 260 A
Voltage of the battery, V = 25.5 V
We need to find the power supplied to the starter motor. We know that,
P = VI
Put all the values,
P = 25.5 × 260
P = 6630 W
or
P = 6.63 kW
So, the power supplied to the motor is 6.63 kW.
