Which of the following is an example of how slowing down the rate of heat transfer improves human life? Group of answer choices

People sitting around a fireplace or campfire enjoy the warmth radiated to them from the fire.

People in cold weather wear several layers of clothes to prevent body heat loss.

The metal in the engine of a car conducts heat to the coolant as people drive.

Heat is carried by convection currents in the atmosphere creating changes in weather.

less than one you can't create energy

i don't understand. explain it clearly

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
