Answer:
Friction
Explanation:
Because the brake pad is rubbing alongside the wheel to slow the body of the car down
Work is equal to the force exerted times the distance traveled. This can be expressed using the following formula:
W = F × D
Insert any known values into the formula above:
W = (70 N) × (9 m)
Simplify the right side of the equation:
W = 630 N·m
The work done is equal to 630 J.
I hope this helps!
The force applied on the fly and the windshield are equal based on Newton's Law of Action and Reaction. the difference between them is that the fly's body does not have enough mechanical strength to withstand the force but the windshield does.
Answer:

The flow rate is defined as the volume of fluid passing through the area per unit of time.
Where A is the surface is the surface area, l is the length of a cylinder, and v is speed flow.
If we solve the equation for speed flow we get:
When we plug in the numbers we get:
