Example 1: Using Power Formula in Physics Here is an example of how to use the power formula. Consider the example above where a person applies a force to move a crate. The person applies a force of 7 N and moves the crate 3 m. This takes the person 9 seconds. What is the power...
What if the work is given in kilojoules (kJ)?Convert the work from kilojoules to joules by multiplying by 1000 before applying the formula. How does time affect power?Power is inversely proportional to time for a constant amount of work; the less time it takes to do work, the greater the...
The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh Unit The SI unit of energy is Joules (J). Power Definition Power is defined as the rate at which work is done. Formula The formula for power is P ...
unit time. The SI unit to calculate the power is watt (W, which is equal to one joule per second. In other words, it is defined as the rate at which the work is done. Power is a scalar quantity. It always depends on the work done. The formula to calculate the power is given ...

Power—law mass inflation in Einstein—Yang—Mills—Higgs black holes DV Gal’Tsov,EE Donets 被引量: 0发表: 1997年 Mass variation formulae for Einstein-Yang-Mills-Higgs and Einstein-dilaton black holes We consider the "first law" of black hole physics for stationary Einstein-Yang-Mills-Higgs...
name any cell and refer to that name throughout the workbook. It adds a level of indirection that allows you to move that cell reference by name rather than by location. And inspiring the introduction into Power Fx, it also allows you to bind a name to a formula that isn’t in a ...
If the antenna is a directional antenna, we need to take into account the antenna gain, and the formula used to calculate the power density is as follows: Pd = ERP/(4πR2) = (Pt× Ag)/(4πR2) Once the antenna has radiated energy, bad things, in addition to the natural spreading ...
Using cross entropy as the loss function, the mathematical formula for the function is shown in Eq. (16). $$\begin{aligned} C=\frac{1}{n} \sum _{x}^{} [yln(a)+(1-y)ln(1-a)] \end{aligned}$$ (16) In Eq. (16), y is the expected output and a is the actual output....
We have derived an analytical formula for the excitation-power dependence of the free exciton photoluminescence (PL) intensity. It has been found that the PL intensity I depends on the power of the excitation laser L as I\propto L, where k is the power index. We have deduced the analytica...
