Calculate the change in pe of 8 million kg of water dropping 50 m over niagara falls

"4,000,000,000 J" is the "Potential Energy" of water dropping over "Niagara falls".

Explanation:

The body possess some energy according to the position of the object that is the when an object is placed at a height it stores some energy it is called "Potential Energy".

Formula used to calculate the "Potential Energy" is

Where, "m" is mass of an object given that 8,000,000 kg, "g" is acceleration due to gravity is and "h" is height of the object is 50 m.

Substitute the given values in the formula,

Potential energy =

Potential energy = 4,000,000,000 J

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
