F~1/r²
doubling the distance r, Decreases the force by ¼
Power<span> is the rate of doing work. It is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. We express it as follows:
P = W / t
where W = Fd
F = mg
Therefore,
P = mgd / t
P = (30)(9.81)(20) / 1 = 5886 W</span>
Answer: Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium
