CFCs, carbon dioxide, green house gases and it's effects are responsible for the hole in ozone layer.
Force bc it says the ability to make stuff happen
If a volcano epulses massive amounts of dust into the atmosphere, those two things will/can happen.
The events will last until the dust lays down on the earth.
Explanation:
1) Kicking a ball.
2) Capture the ball by hand.
3) Push a car.
F = normal force by each board on each side
W = weight of the board in between acting in down direction = 95.5 N
f = frictional force in upward direction by each board
= coefficient of friction = 0.663
Using equilibrium of force in Upward direction
f + f = W
f = W/2
f = 95.5/2 = 47.75 N
frictional force is given as
f =
F
47.75 = (0.663) F
F = 72.02 N
