Therefore electric potential is V = 15000V.
What is electric potential?
The amount of labor required to convey a unit of electric charge from a reference point to a given place in an electric field is known as the electric potential (also known as the electric field potential, potential drop, or the electrostatic potential).
length of sparks d = 5 mm = 5 x 10^-2 m
(a) It is possible to find average values for the skin's surface and the electric field in dry air from outside sources. Electric field and spark length can be used to determine electric potential.
V = E.d
V = 15000V

Answer:
a) 3170 kw
b) 377 km^2
Explanation:
Estimate of electric power
a) Given :
Average power consumption for a family of 3 = 108.4 * 106 BTU per year = 0.0317 kw = 31.7 watts
<u>The power requirement for a city of 300000 people </u>
= 31.7 watts * 100000 = 3170000 watts = 3170 kw
b) Given :
Average solar panel insulation = 8.4 W /m^2
<u>Estimate the area of silicon solar cells required to satisfy community power requirement</u>
= (1 * 3170) * (1000/8.4 )
= 377.380 * 10^3 m2 = 377 km^2

Answer:
Athlete A
Explanation:
Power is the rate of doing work and it is calculated as follows:
Power = work done/time taken = mgh/t
(for work being done against gravity)
So for athlete A
P = (100 kg * 9.8 N/kg* 0.6m)/0.5 s = 1176 W
For athlete B
P = (150 kg * 9.8 N/kg* 0.6m)/1 s = 882 W
For athlete C
P = (200 kg * 9.8 N/kg* 0.6m)/2 s = 588 W
For athlete D
P = (250 kg * 9.8 N/kg* 0.6m)/2.5 s = 588
