<em><u>Answer:</u></em>
Solids
<em><u>Explanation:</u></em>
<u>Solids</u> have definite shapes and definite volumes. The forces of attraction between the molecules of a solid substance are strong and the intermolecular spaces are very small. Due to this, the motion of molecules within a solid substance are very difficult that they only vibrate in their positions.
<u>For liquids</u>, they have definite volumes and indefinite shapes. The forces of attraction between the molecules of a liquid are intermediate and the the intermolecular spaces are intermediate as well. Due to this, the motion of molecules within a liquid substance is not as difficult as it is within solids.
Finally, <u>for gases</u>, they have indefinite shapes and indefinite volumes. The forces of attraction between the molecules of a gas are weak and the intermolecular spaces are large. Due to this, the motion of particles of gas is very easy.

The speed of car is 106.67 miles per hour
To solve problems involving speed and distance we are required to first find speed or distance travelled in an hourly timeframe
It is given that car takes 4 hours to cover the distance at a speed of 40 miles per hour
Therefore, total distance travelled by the car= speed x time
= 40 miles per hour x 4 hour
=160 miles
We are required to find the speed of the car if the distance is to be covered in 1.5 hours
We are required to find the speed by the formula speed= Distance/time
distance= 160 miles time = 1.5 hour
speed= 160/1.5=106.666=106.67 miles per hour
Hence the speed is 106.67 miles per hour

Answer:
The object with the greater mass will have the greater momentum
Explanation:
The momentum of an object with mass <em>m</em>, moving with velocity <em>, </em>is given by the formula
M = <em>mv</em>
<em />
Since both objects have the same velocity <em>v, </em>it is clear that the object with the bigger mass will have the greater momentum
Answer:A:The track pushes back on Clinton's shoe with the same force.
Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.
