-- The quantity 'RC' has the physical dimensions of Time.
-- If the capacitor is charging through a resistor, then 'RC' is the time it takes to
charge up to (1 - 1/e) of the voltage it still has to go to become fully-charged.
-- If the capacitor is discharging through a resistor, then 'RC' is the time it takes to
discharge to 1/e of its present voltage.
-- ' e ' is the base of natural logarithms, approximately 2.71828...
-- 'RC' is called the 'time constant' of the resistor/capacitor combination.
P= M/No
Yes. The ideal pendulum consists of a massive bob suspended from a frictionless pivot by a massless string. For small angles the period is given by the formula: t = 2*pi*sqrt(l/g) However, the formula depends on the assumption that, for the angle of displacement x (measured in radians), sin(x) approximately equals x. For large x the approximation does not hold true and so the formula needs amending. For x = 0.4 radian, the period is about 1% greater than that given by the unadjusted formula.

Just swap the letter around in the formula that you are given!
it's for finding either the density, mass, or volume of something when given the other two.

No. I is as described for the stated period.

the formula for energy stored in a capacitor is (1/2)*cv^2 given v=20v, c =10*10^-6 f by using this information you can easily calculate the energy

The formula to find the time period (T) of a wave is: T = 1 / frequency (f). Time period is the amount of time it takes for one complete cycle of a wave to pass a given point.
