Atmospheric pressure is caused by the weight of the atmosphere pushing down on itself and on the surfae below it?

Atmospheric pressure is when you move your hand through the air and you can feel the air on it

Atmospheric pressure is when the weight of the atmosphere is pushing down on itself and the surface above it.

All directions

down

Because it is invisible and you cant feel it.

Because atmospheric pressure exerts force in all direction, so as well as going up it also acts downwards so the forces are balanced.

When the clockwise and anti clockwise moments are the same.

When the clockwise moment and anti clockwise moment cancel each other out.

When the clockwise moment is bigger than the anti clockwise moment.

When the anti clockwise moment is bigger than the clockwise moment

Hookes law states that the extension of the spring is the same as the spring constant

Hookes law states that the Force should be multiplied by the extension of the spring.

Hookes law states that the extension of the spring is directly proportional to the force of the spring.

Force = Spring consistency x Extended spring

Force=Spring constant x Extension of the spring

Spring Consistency = Force x Extended spring

Speed = time + distance

Speed = distance/time

Speed=distance x time

s=d x t

v= s/t
