Explanation:
what to do with it please write it properly
Pressure = (force) divided by (area)
But force and area are both derived units themselves.
-- Force = (mass) times (acceleration)
But acceleration is a derived unit itself.
Acceleration = (length) divided by (time squared)
So force = (mass) · (length / time squared)
-- Area = (length squared)
So pressure = (mass · length / time-squared) / (length-squared)
<em>Pressure = (mass) / (length · time-squared)</em>
That sure looks to me like it's derived from a bunch of other stuff.
D. Sound wave, because they (sound waves) need air molecules to travel. Just like in space, there is no air and therefore no sound (since space is a vacuum). Hoped this helped!
Answer:
3.0 x 10¹ Nm
Explanation:
Torque = F x r
Where F is force applied and r is perpendicular distance from pivot point . r
is also called lever arm
Here F = 15 N and r = 2.0 m
Torque
= 15 N X 2.0 m
= 3.0 10¹ Nm.
Gas and solar power I think
