Electric power law: P = V x I   P = power in watts   Einstein's law: E â¦ = m x cÂ²   E = energy in joules, m = mass in kilograms, and c is the speed of light.
A cat had climbed at the top of the tree. Answer: 1,176J define variables: - m = 6 kg, h = 20 m, g = 9.8 m/s2 find formula for determining potential energy: - PE = mgh plug in numbers for variables: - PE = 6 x 9.8 x 20.
