Amarble is on a table 2.4 m above the ground. what is the mass of the marble if it has a gravitational potential energy of 568 j?

Mass of the object, m = 24.14 kg

Explanation:

It is given that,

Height above the ground, h = 2.4 m

Gravitational potential energy, PE = 568 J

We need to find the mass of the marble. The definition of gravitational potential energy is given by the product of mass, height and acceleration due to gravity. i.e.

PE = mgh

m = 24.14 kg

So, the mass of the object is 24.14 kg.

c.the charges if the proton and electron and gravity

c)as speed changes, wavelength and frequency change.

everything changes!
