Answer:
Battery voltage will be equal to 9.65 volt
Explanation:
We have given capacitance 
Resistance 
Time constant of RC circuit is
Time is given t = 0.15 sec
Current i = 0.46 mA
Current in RC circuit is given by
V = 9.65 volt
So battery emf will be equal to 9.65 volt
Answer:
38.024 KWh
Explanation
250 watts multiplied with 5 hours daily multiplied with 28 days monthly equals 35000 Watt hours. Divided by a 1000 to get the KWh equals 35 KWh.
= 250×5hrs× 28days
= 35000watts
= 35000/1000
= 35KWh
Four 6 watt lightbulbs equals 24 watts 4x6=24
Hence, 24×4.5hrs×30days
= 3024watts
= 3024/1000
= 3.024KWhr
The total amount of energy consumed in the month of February = 35 KWh + 3.024 KWh = 38.024 KWh
Note that I had to use 28days since we are considering the month of February.

The difference between them is that
velocity is the speed with a direction, whereas speed does not have a direction.
