Which of the following statements does not explicitly describe a transfer of money a. a ball dropped from a heigh hits the ground with a high speed. b. the collision produced in a nuclear reaction heat up the surroundings. c. a plane increases its air speed from 150 mi/hr to 200 mi/hr. d. the electricity from the power socket causes the fan to turn.

The correct answer is A.

Explanation:

A. A ball dropped from a heigh hits the ground with a high speed: This event does not produce any economic benefit.

B. The collision produced in a nuclear reaction heat up the surroundings: This process describes a heat transfer, which is used in nuclear reactors to produce energy, which translates into economic benefits.

C. An plane increases its air speed from 150 mi/hr to 200 mi/hr: In this case, the consumption of extra gasoline to increase the speed of the plane produces a loss of money.

D. The electricity from the power socket causes the fan to turn: Using an electrical appliance consumes current, which must be paid for and produces a waste of money.
