Explain about gravitational and elastic potential energy. Does temperature has any effect on the speed of a wave? Explain why or why not. Explain how is surface tension related to surface energy. 1. Define electric potential 2. What is electric energy? Describe briefly the electric energy. 3....
(In effect, we store electricity as gravitational potential energy, which we can do indefinitely, and turn it back to electricity when it suits us.) Photo: How pumped storage works: When there's lots of cheap electricity about (at night or when the wind is blowing), water is pumped up ...
1) We should not, as the current explanation does, say that the particles gain energy. The Law of Conservation of Energy strictly demands that we say, instead, that they convert gravitational potential energy into kinetic energy, but only as much as the resulting pressure, resisting gravitational...
Forces that exist in nature have been classified into four categories: Gravitational force, electromagnetic force, strong force and weak force. While the first two forces are long-range forces, the other two act at nuclear distances. It has been proposed that all the four forces are ...
The energy you use isn't lost, but stored by your body as gravitational potential energy, which you could use to do other things (whizzing down a slide back to ground level, for example).What you do when you climb steps, ladders, mountains, or anything else is work against Earth's ...
Summing up, in the JF(E), where energy is conserved but energy-momentum is not, photons are the means of measuring length, time and mass. Proper mass increases with gravitational potential energy an...
In particular, we conclude that high-velocity, high-powered jets cannot be produced in gravitational potentials produced by stellar clusters. However, the more general notion of the twin-exhaust mechanism 1 , in which the central potential can be cusp-like near a massive black hole, is not ...
The three height levels with different gravitational potentials loosely correspond to West zones34. The normal, shunt, and dead space compartments correspond to those of the Riley model35,36. Perfused compartments received deoxygenated mixed venous blood and returned end-capillary blood with oxygen ...
be below the Moon's gravitational binding energy, which, since the Moon is densest near its center, is much greater than 3Gm2/5r = 1.2x1029joules, so the Moon would not be immediately entirely destroyed. It is, however, about the right amount of energy to liquify the entire Moon, if ...
Consequently, in the first half of the stance phase, kinetic energy is converted into gravitational potential energy (Cavagna et al., 1976, Cavagna and Franzetti, 1986), whereas in the second half of the stance phase, the opposite conversion occurs. Over the gait cycle, the CoM has a ...
