Time taken by the rubber-soled shoes to reduce a person's potential from 3.00×10³ V to 100V is 3.91s
The initial potential difference
is related to the final potential difference
by

Our target is to find t, so we rearrange equation (1) for t to be

The body has a capacitance 150 pF while the foot has a capacitance 80 pF and both are in parallel connection. So, the equivalent capacitance is

The shoes of the rubber-soled has resistance
. Plug the values for
and C into equation (2) to get the time t.

A magnetic field is produced by moving electric charges so B
It Would Take Aprroximately 1000 Years.
Explanation:
We have,
Ajoba and Prav drive to work. Ajoba drives 45 miles in 2.5 hours. Prav drives 74 km in 1 hour 15 min.
1 mile = 1.6 km
45 miles = 72.42 km
74 miles = 119.0 km
1 hour 15 min means 1.25 hours
Average speed of Ajoba is :

Average speed of Prav,

Difference in average speed of Ajoba and Prav is :

So, the difference in average speed of Ajoba and Prav is 66.24 km/h.
Answer:d
Explanation: oil would form droplets but only tiny ones because it’s surface tension is lower than that of water
