2. - B.

3. - True.

4. - B.

5. - D.

Explanation:

2. To find the speed in feet per minute, you need to divide the time by time and divide the feet by the time

2/2 = 1 minute

100/2 = 50 feet

3. 45 N - 20 N = 15 N

So the difference between the forces is 15 N

4. As just about everyone knows, when something falls, that is because of gravity. Gravity is the force that pulls everything.

5. Inertia is when an object stays unchanged. So if something stays in motion or does not stop, it has not changed

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
