Other formulae for the back vertex power of a lens (or an optical system) are where d is the thickness of the lens, n the index of refraction of the lens, F1 the power of the front surface, F2 the power of the back surface and Fe the equivalent power. The powers are in dioptres...
elements then the formula to find the number of subsets of a set in a power set is given by: |p(a)| = 2 n for example, set a = {1, 2, 3} n = number of elements of a = 3 so, the number of subsets in a power set of a will be: subsets of a = {}, {1}, {2},...
If the work is done at a uniform rate, power is defined by the formula N = A/t, where A is work done during the time t. In the general case N = dA/dt, where dA is the elementary work done during an elementary time interval dt (usually 1 sec). Power is measured in watts and...
power formula unit of power solved example important points about power what is power? we can define power as the rate of doing work, it is the work done in unit time. the si unit of power is watt (w) which is joules per second (j/s). sometimes the power of motor vehicles and ...
