state and explain the general law of conversation of energy discuss the energy changes when a ball is released from the top of Tower which energy is possessed by the ball when at the top what energy does it poses just before loading on earth but after ruling on Earth it has no energy does the law of conversation of energy violated here? |
|
Answer» ok but MARK me as brainliestExplanation:3.6 & 3.7 The Law of CONSERVATION of Energy. KE + PE = constant. ... When the ball is at the TOP of its SWING, all of the pendulum's energy is potential energy. When the ball is at the bottom of its swing, all of the pendulum's energy is KINETIC energy. |

The parallelogram law is avoided by |
|
Answer» the parallelogram law in an inner product space guarantees the uniform convexity of the corresponding norm on that space. This APPLIES to L2(Ω). Now we will develop certain inequalities due to Clarkson [Clk] that generalize the parallelogram law and verify the uniform convexity of LP (Ω) for 1 < p < ∞.We begin by preparing three TECHNICAL LEMMAS needed for the proof. |
