Jun 4, 2018 · Electric potential energy or kinetic energy is the source of electrical energy. two types of electric motors transform electrical energy into mechanical energy. Alternating current is transformed into mechanical power by an AC motor. Direct current is transformed into mechanical power by a DC motor. #SPJ2. brainly.in/question/33831550
Sep 26, 2020 · Answer: mechanical energy, sum of the kinetic energy, or energy of motion, and the potential energy, or energy stored in a system by reason of the position of its parts. Mechanical energy is constant in a system that has only gravitational forces or in an otherwise idealized system—that is, one lacking dissipative forces, such as friction and ...

May 13, 2020 · Order of energy conversion in thermal power plant (b) Heat energy → Mechanical energy → Electrical energy. About Thermal power station: A thermal power station is a type of power plant that converts heat energy into electricity.
we have to show that the total mechanical energy of a freely falling body remains constant throughout its fall. proof: Let a particle is falling from a height h. initial velocity of the particle, u = 0. so, kinetic energy of the particle must be zero. potential energy of particle, P = mgh. case 1: Total mechanical energy at height h, T.E = mgh ...
Nov 2, 2017 · Therefore, kinetic energy, T = 0 and potential energy, U = mgh Hence, total mechanical energy at point A is E = T + U = 0 + mgh = mgh ... (i) At Point B : Suppose the ball covers a distance x when it moves from A to B. Let v be the velocity of the ball point B. Then by the equation of motion v^2-u^2 = 2aS, we have v^2 - 0 = 2gx or v^2 = 2gx ...
May 21, 2020 · The mechanical energy thus formed gets transformed into heat energy. When we stop rubbing our hands for a couple of seconds, they cool down again due to the convection of heat to the atmosphere. Advertisement
