Answer:
thermodynamics
Explanation:
The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.
I'd say B.) Increasing the voltage of the battery.
For B, it is because water is a really good conductor of electricity, so the electrician will get shocked
Changes. :) I think... Whats your question
?
Answer:
The final kinetic energy of the two-car system is 60,000 J.
Explanation:
Given;
mass of the car, m = 1200 kg
time of motion, t = 8.8 s
final velocity of the car, v = 10 m/s
Apply the principle of conservation of kinetic energy; the initial kinetic energy is equal final kinetic energy.

Therefore, the final kinetic energy of the two-car system is 60,000 J.
