Rocket-powered sleds are been used to test the responses of humans to acceleration. Starting from rest, one sled can reach a spe

ed of 495 m/s in 1.78 s and can be brought to a stop again in 2.16 s.
Find the acceleration of the sled while accelerating.
Please be very thorough in your answer, I have a very hard time understanding if you don't.
Also, find the acceleration of the sled when braking.

Heat is applied to an ice cube in a closed container until only steam is present. draw a representation of this process, assumin
olga55 [171]
The solid, liquid and gas phases of water would have the same structure of the molecules since they are same substance. The only difference would be the distances of the molecules in the container. For a ice, the molecules are close to each other where the molecules vibrate only in place. For liquid, the molecules are freely moving and are at some distance with each other but not that far away with each other. Steam, on the other hand, would have molecules that are very far from each other and are freely moving in the whole container. As the container is heated, the size of the molecules would not change. It is only the volume that has changed. Also, the mass is the same since there is no outflow of the substances.

Leah watches a toy car move across a table at a constant speed. The car moves across the table in one direction and falls off th
Sedbober [7]

In order to change the direction and speed, a net external force is required. A net external force is an unbalanced force which will change the direction and gives the speed in the opposite direction. Hence, its an unbalanced force from the joey that pushes the car in the other direction due to which it the car starts to move back to Leah. Without, unbalanced force there is not change in the direction of the car's motion.

Hence, option B is correct.
