Brian has an object suspended in the air. it has a mass of 100 kg and is 25 meters above the ground. what is the object’s potential energy

P.E = 24500

Explanation:

Potential energy is the energy possessed by a object in a position. An object can store energy as a result of it position. An example is having a ball held upward by a pavement. The stored energy by the ball is known as the potential energy.

Since the object is suspended upward with a height of 25 meters , gravity is involved. Gravitational potential energy is the energy stored by an object as a result of it height.  Gravitational potential energy is dependent by the height which the object is raised and the mass. The higher the height of an object is raised the greater the gravitational potential energy.

The formula for gravitational potential energy is as follows ;

P.E = mass × height ×  gravitational field strength(9.8N/kg)

P.E = mgh

m = 100 kg

height = 25 meters

g = 9.8 N/kg

P.E = 100 × 9.8 × 25

P.E = 24500

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
