Answer:
A) Air resistance acts in a direction opposite the the fall of an object reducing it by doing work against the weight of the object due to gravity.
B) using a ping pong ball, the time of fall will be greatly reduced since it has little weight (its mass x acceleration due to gravity) against the air resistance. The net downward force of the weight and the air resistance will be small.
C) No, I wouldn't expect them to fall at the same time. The steel ball will have more weight compared to the ping pong ball and hence it will have a larger net force downwards.
D) If they are both released from a 6 m height, the steel ball will fall to the ground first since it has a larger net force downwards.
The correct answer is A. an increase in Earth's average surface temperature.
While all of these are aspects of global warming, option A best summarizes it.
The energy chain diagram in this case is chemical energy >> energy conversion >> motion (kinetic) energy + thermal energy.
<h3>What is an energy chain diagram?</h3>
An energy chain diagram is a graphic representation indicating the conversion between different types of energies.
Kinetic energy is a type of motion (movement) energy generated by using potential (stored) energy.
Chemical energy (in this case, the fuel of the car) is a type of energy that is stored to perform work.

The answer is evolution. When a specifies evolves over time they change and adapt to their environment.
