Radiant Energy Radiant energy is the energy of electromagnetic radiation. It is measured in units of joules, and denoted by the symbol:(电磁辐射的能量。 它以焦耳为单位测量 单位j=joules) intensity The radiant (luminous) intensity is the power per unitsolid angle (?)emitted by a point light s...

ECS is an idealized but central measure of climate change, which gives specificity to the more general idea of Earth’s radiative response to warming. This specificity makes ECS something that is easy to grasp, if not to realize. For instance, the high heat capacity and vast carbon stores of...
E = 1/2 Li² energy E is in Joules, and I is in ampere. An ideal inductor has zero resistance and zero capacitance. However, real inductors have a small value resistance associated with the winding of the coil and whenever current flows through it, energy is lost in the form of heat...
The unit volts (V) is defined as joules per coulomb, i.e., it conveys energy (in joules) per coulomb of charge. The ampere (A) is coulombs per second, i.e., how many coulombs of charge pass a given point in one second. We can use this information to...
The unit of measurement for power is the Watt, which is defined as 1 Joule of work per second. So, multiplying the steady power rate in a DC circuit by the time we keep it powered will result in an answer of joules (total energy dissipated by the resistor): Work=(V2R)t Showing ...

Solution: As given here, Mass of the body, m = 250 Kg, Velocity of it, v = 10 m/s, So Kinetic energy will be as: E =12mv2 E =12×250×102 = 125 ×100 E = 12500 joules Therefore, kinetic energy will be 12500 joules.
Power is the amount of energy that is converted to a unit of time. Expect to pay more when demanding higher power. André-Marie Ampèrewas a French physicist and mathematician. The SI unit of measurement of electric current, theampere, was named after him. ...
Voltage is the measure of electrical “push” ready to motivate charges to move through a conductor. In scientific terms, it is the specific energy per unit charge, mathematically defined as joules per coulomb. It is analogous to pressure in a fluid system: the force that moves fluid through...
