268653 A tank of size \(10 \mathrm{~m} \times 10 \mathrm{~m} \times 10 \mathrm{~m}\) is full of water and built on the ground. If \(g=10 \mathrm{~ms}^{-2}\), the potential energy of the water in the tank is

268654 A bolt of mass \(0.3 \mathrm{~kg}\) falls from the ceiling of an elevator moving down with an uniform speed of \(7 \mathrm{~m} / \mathrm{s}\). It hits the floor of the elevator (length of the elevator \(=3 \mathrm{~m}\) ) and does not rebound. What is the heat produced by impact?

268655 A spring when compressed by \(4 \mathrm{~cm}\) has \(2 \mathrm{~J}\) energy stored in it. The force required to extend it by \(8 \mathrm{~cm}\) will be

268656 The elastic potential energy of a stretched spring is given by \(\mathrm{E}=50 x^{2}\). Where \(x\) is the displacement in meter and \(E\) is in joule, then the force constant of the spring is
