Begin with the equation of the time-averaged power of a sinusoidal wave on a string: P = 1 2 μ A 2 ω 2 v. P = 1 2 μ A 2 ω 2 v. The amplitude is given, so we need to calculate the linear mass density of the string, the angular frequency of the wave on the string, and the speed of the wave on the string.

The Principle of Conservation of Energy states that energy cannot be created or destroyed. Therefore, if the body does useful work to transfer mechanical energy to its surroundings (), or transfer thermal energy to the environment as heat, then that energy must have come out of the body’s internal …

WebAs discussed above, mechanical energy is the sum of potential and kinetic energy of an object. This sum always remains constant. The reason for the mechanical energy of an object to remain constant is that it does not increase or decrease based on external factors. But, it only depends on the physical properties of the object under consideration. WebWhen energy demand is high, the flow is reversed. The pump becomes a generator driven by the gravitational potential energy of the water in the upper reservoir. The water can be released very rapidly to accommodate the peak powerneeds of a …

WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s.

WebMechanical energy is energy stored in objects by tension. Compressed springs and stretched rubber bands are examples of stored mechanical energy. Nuclear energy is energy stored in the nucleus of an atom—the energy that holds the nucleus together. Large amounts of energy can be released when the nuclei are combined or split apart. great lengths extensions buntIn physical sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes.
