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.

Have a nice day!

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
