Question

Which of the following is a scientific definition of Power? Select one: Oa. The condition in which the inputs into a reservoir are equal to the outputs from the reservoir and so the size of the reservoir is not changing with time. O b. The distance between crests of a wave.(Units: meter) c. The rate of energy transferred per unit area O d. Radiation that is can travel as a wave through a vacuum and which carries energy with is as it travels. This type of radiation comes in a spectrum of wavelengths and includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. O e. The energy used per unit time. O f. The fraction of light that reaches an object that is passed through the object without being reflected or absorbed. O g. The fraction of light that reaches an object that is absorbed. O h. The radiation emitted by an ideal object that increases with the temperature of the object, and that is most intense at a wavelength that decreases with the temperature of the object. O i. The amount of deviation between an observation and the accepted normal value of that quantity O . The number of crests of a wave that passes in a unit time. (Units: cycles per second). O k. The capacity to do work. L. The fraction of light that reaches an object that is reflected

Explanation / Answer

e- The energy used per unit time

The unit of the power is Watt, which is equal to 1 Joule/second(energy/time)
