What is the energy equivalent of an object with a mass of 23 g

0.207x10^16 Joules!

Explanation:

Using Einstein's law of mass energy, we know that the energy of a matter is:

E = mc^2

where, m [kg] = mass

c [m/s] = speed of light

In this case:

m=23g = 0.023kg.

c = 3×10^8m/s (This is an aproximation)

Then:

E = mc^2 = (0.023kg)(3×10^8m/s)^2 = 0.207x10^16 Joules!

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

the answer would be 32*f
