Explanation:

From the question we are told that

From the question we are told to find when t=0  equals the time constant ()

That is to obtain .This  is mathematically represented as

             Substituting 12 V for and 150Ω for R

From the question we are told to find when t=0  equals the 3 times the  time constant ()

That is to obtain .This  is mathematically represented as

As tends to infinity

So would be mathematically evaluated as

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
