Explanation:
It is given that,
Inductance of the inductor,
Resistance of the resistor, R = 10 ohms
(a) Let is the time constant of the circuit. It is given by :
(b) The current equation in RL circuit is given by :
I' = 0.99 I
t = 4.6 ms
Hence, this is the required solution.
When light changes the medium it travels through it also changes speed. The speed in medium is given by formula:
Rearranging formual gives:
From this formula we can make conclusion that index of refraction is inversely proportional to speed of light in medium. This means that greater speed gives smaller index of refraction.
In metric that means multiplying or dividing by 10, 100, 1000, etc. It consists of a partial word like "kilo" or "milli". For example, the prefix "kilo" means "times a thousand" or " one thousand of" the units in question. So "kilometer" means one thousand meters and "kilogram" means one thousand grams.
