Ep = mgh
= (35)(9.8)(3.5)
= 1200.5 J
Ek = (1/2)(mv^2)
= (0.5)(35)(5^2)
= 437.5 J
When the suns energy moves through space it reaches earths atmosphere and finally the surface it warms the atmosphere and becomes heat energy then its transfared throughout the planets system by radiation conduction and convection
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.
Should be C). metamorphic rocks change when heat and pressure are applied like coal into a diamond.
