Calculating the Energy of an Isolated Charged Sphere - советы от нейросети

Уединенный шар радиусом 370 мм имеет заряд 637 нКл. Какой энергией обладает шар?

The energy of an isolated sphere with a radius of 370 mm and a charge of 637 nC is 12.348 joules. This can be calculated using the formula E = k * Q^2 / R, where k is the Coulomb's constant (9*10⁹ N*m²/C²) and Q is the charge in Coulombs. In this case, the radius must be converted to meters for the formula to work, so 370 mm = 0.37 m. Plugging in the values, we get E = (9*10⁹ N*m²/C²) * (637*10^-9 C)^2 / 0.37 m = 12.348 J. This is the energy required to move the charged sphere to an infinite distance from any other charges. If you are still having trouble with these calculations, try breaking down the problem into smaller steps and checking your work along the way. Overall, this is an elementary physics problem and you should have no trouble solving it with some patience and practice.
