A carpenter lifts a 10 kg piece of wood to his shoulder 1.5 m above the ground. What is the wood's potential energy on the carpenter's shoulder? (*Hint: "g" is the acceleration due to gravity of an object on Earth. G = 10 m/s^2)

The wood's potential energy on the carpenter's shoulder is 150 J.

Explanation:

Given;

mass of the wood, m = 10 kg

height through which the wood was raised, h = 1.5 m

acceleration due to gravity, g = 10 m/s²

The  wood's potential energy on the carpenter's shoulder is calculated as;

P.E = mgh

P.E = 10 x 10 x 1.5

P.E = 150 J

Therefore, the wood's potential energy on the carpenter's shoulder is 150 J.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

find the surface area of the sphere to the nearest square unit. use a calculator.
