The number of kilowatts used by an individual to operate his appliances is determined as 12.1 kWh.
<h3>
Average daily power consumption</h3>
The average daily power consumption is the amount of electric energy consumed by an individual on a daily rate.
The average daily power consumption of individuals in USA is 12,100 W-hr.
<h3>Converting watts to kilowatts</h3>
E = 12,100 Whr/1000
E = 12.1 kWh
Thus, the number of kilowatts used by an individual to operate his appliances is determined as 12.1 kWh.

Explains the fine structure of Hydrogen lines.
<h2>
Tension in tow line is 2000 N</h2>
Explanation:
Power is the ratio of work and time.
Work = Force x Displacement
W = F x d
Here force is tension, T
So
W = T x d
Substituting
We have
Power, P = 30kW = 30000 W
Velocity, v = 15 m/s
Substituting
30000 = T x 15
Tension, T = 2000 N
Tension in tow line, T = 2000 N
