Your grandmother places a pitcher of iced tea next to a plate of warm, freshly baked cookies so that the pitcher and the plate are touching. you tell your grandmother that the plates are in thermal contact, which means thata. heat flows w/in the warm plate but not w/in the cold pitcherb. heat flows from warm plate to cold pitcher and from cold pitcher to warm platec. heat flows from cold pitcher to warm plated. heat flows from the warm plate to the cold pitcher

a) heat flows from the warm plate to the cold one

Explanation:

Heat is an expression of energy, the bodies with more heat mean that they have more energy.  In this way, they can share or pass this "excess" of energy to the cold body. Both plates are not in total contact but some part are close enough (they are touching) that the heat can pass from one to the other. Also the heat always need a media to travel, in this case, the air that surrounds the plates is also the media that the heat travels from the hot to the cold one.

divide the right side by the left side

0.024÷1.2=0.02 for example

we need to know the time interval during which the force acts. impulse of force = momentum change
