Answer:
effort force: The force used to move an object over a distance. resistance force: The force which an effort force must overcome in order to do work on an object via a simple machine. ideal mechanical advantage: The factor by which a mechanism multiplies the force put into it.
Explanation:
Answer:
12.5 J
Explanation:
Force, F = 25 N
Distance, d = 0.5 m
The direction of force and the displacement is same.
Work is defined as the product of force in the direction of displacement and the displacement.
Work = Force x displacement x CosФ
Where, Ф be the angle between force and the displacement
Here, Ф = 0°
So, W = 25 x 0.5 x Cos0°
W = 12.5 J
Hi there,
Burning fossil fuel should be a cause. Using aerosols also would be a cause.
Smog is an effect of air pollution. As well as acid rain, also I believe that loss of the ozone layer should be an effect of air pollution. I believe that volcano eruptions should be an cause of air pollution
I believe that smog reducing filters should be in the prevention box, as well for using electric cars.
