<u>Answers</u>

1) Reaction

2) Gravitational force

3) Frictional force


<u>Explanation</u>

Reaction is directly opposite and equal to action(normal force). The normal force is the weight. So we can say that reaction supports the weight of the car.

Objects fall downwards due to acceleration due to gravity. The acceleration force is provided by the gravitational force. The car is accelerated downwards by the gravitational force.

Frictional force is the force that opposes relative motion between two bodies. When iar is involved, we call it viscosity. So the force that acts against the motion of the car is friction.

how could the specific heat of the substance your container will hold affect the performance of the container?
ratelena [41]

Answer:

I am not entirely sure, but I hope this helps ;)

Heat transfers from a very hot body always, and into a colder body. This is due to the change in temperatures at which the two bodies exist, and also it depends upon its magnitude. And, the heat exchange stop once both the bodies attain same temperature.

And from the relation of heat equation, we get that it is directly proportionate to the substance's specific heat. But, there is no such thing that the area of contact is important, for heat transfer. It gets transferred although a small point is in contact.
