A weight lifter lifts a set of 212 kg weights to a height of 1.75 m. How much potential energy to the weights now have?

Potential energy = 3635.8 Joules

Explanation:

Given that,

Weight lifted by a weight lifter is 12 kg

It lifts to a height of 1.75 m

We need to find the potential energy to the wights now have. The energy possessed by an object due to its position or height above ground is called potential energy. Its formula is given by :

P = mgh

g is the acceleration due to gravity

So, the potential energy is 3635.8 joules.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
