Explanation:

P= rho×g × h (g=10 m/s²) ,

(rho=1000 kg/m³)

P= 1000×10×5= 50,000 N/m² (C)

the binding energy is the energy required to create z separate protons and n=a-z separate neutrons from a (a,z) nucleus in its ground state. another way to think about it is binding energy is the mass energy which is missing from a nucleus compared to the mass energy of the individual nucleons.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
