Answer:
a
b
c
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
Average speed = total distance / total time
total distance = 40 + 20 = 60km
total time taken = 10 + 5 = 15 minutes
Average speed = 60/15 = 4km/min
