cp-cv =R proved that//
The equation is referring to: * H = Heat in Watts * I = Current in Amperes, (therefore I2 = Current squared) * R = Resistance in Ohms * T= Time in Seconds or .....The amount of heat in a conductor would be: Current (Squared) x Resistance x Time
Joule's law, which states the relationship between electrical power, current, and resistance, is derived from Ohm's law, P = IV, and the formula for electrical power, P = I^2R. By substituting I = V/R from Ohm's law into the power formula, you can derive Joule's law as P = V^2/R.
That is done via calculus. Specifically, take the movement over a small distance, calculate the change in velocity divided by the time, and figure out what happens if the time interval gets smaller and smaller - as they say in calculus, "get the limit of the acceleration as the time tends towards zero".
Use the equation, V= IR from Ohm's Law V is the voltage, I is the current, and R is the resistance in ohms So then, solve the equation for I (the current) and you get I=V/R. Then just plug in the values... I= 12/3, which equals 4 A. (For current, it is measured in amperes, or just "A" as the unit.)
The equation for orbital velocity is (v = \sqrt{\frac{GM}{r}}), where (v) is the orbital velocity, (G) is the gravitational constant, (M) is the mass of the central body, and (r) is the distance from the center of mass.
It is a linear equation in one variable r. The solution to the equation is r = 1.

It is an equation in the variable r.
r=0 is the solution...
100 r = 99.52Divide each side of the equation by 100 :r = 99.52/100 = 0.9952
