Question

a bell hanging at the top of a tower has 8,550 j of energy. If it has a mass of 20 kg, find the hight of the bell

Answer 1

Answer:

There were several factors that contributed to the decline of the Old Kingdom, but the most important issue was the erosion of the authority of the Pharaoh and the accompanying growing power of the nobility and priesthood. This led to the decentralization of power in Egypt and constant power struggles and civil war.

Answer 2

43.62m

Explanation:

Given parameters:

Energy = 8550J

Mass of bell = 20kg

Unknown:

Height of the bell = ?

Solution:

As this state, the bell possesses potential energy. Potential energy is the energy at rest in a body. It is due to the position of the body.

 Potential energy = m g h

m is the mass of the body

g is the acceleration due to gravity of the body

h is the height of the body

The unknown is h and we should solve for it.

 g = 9.8m/s²

    Input the variables;

       8550 = 20  x  9.8 x h

    h = 43.62m

hope it helps:)
