Answers

Answer 1
Solid!! Because a gas has very loosely packed molecules and a liquid has somewhat loosely packed molecules! :)
Answer 2

Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its ---------------- energy increases and its ---------------------------- decreases.

Answers

Answer:

Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its -------Potential --------- energy increases and its -----------kinetic----------------- decreases.

Explanation:

Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. ... As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

kinetic//the movement energy
potential//energy by position

The average speed of the blocks are 0.36 m/s.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed with respect to time. As at time t = 0 , the speed is also zero, and at time t = 2.5 s , the speed will be
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
The answer is 0.36 m/s credit to the guy above me (give him Brainlyist) but I also had to do this assessment.
