Take a look at the picture. The speed of the connected cars is 1/4 of the single car’s speed, and the kinetic energy is 1/4 of the single car’s kinetic energy
Answer:

Explanation:
Each time the work done to raise a given mass is

here we know that


now we have


since it is just 25% of actual energy consumed as we know its efficiency is 25%
so we have total energy consumed in this way


now if it took N number of times so burn the fat of a pizza then


Answer:
B. If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.
C. If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.
E. If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.
