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.

I hope it helps. :).
A fiber-optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers; one cable can have as few as two strands or as many as several hundred. Light travels down a fiber-optic cable by bouncing repeatedly off the walls. If<span> light hits glass at a really shallow angle (less than 42 degrees), it reflects back in again—as though the glass were really a </span>mirror<span>. This phenomenon is called </span>total internal reflection<span>. It's one of the things that keeps light inside the pipe.</span>
Explanation:
Balanced forces will cause no change in the speed of an object.
Answer:
Because the weight depends of the gravity
Explanation:
This is because weight and mass are different, in order to better understand this problem we will apply an example with real values, which will help us to determine a person's weight.
A man has a mass of 80 [kg] on Earth when measuring his weight he realizes that it is 784.9 [N] and on the moon it is 130.8 [N]
<u>On Earth</u>
<u />
Where:
g = gravity
<u>Weight on the moon</u>
<u />
Wm = 80 * 1.635
Wm = 130.8[N]
<u>Weight on the earth</u>
<u />
We = 80 * 9.81
We = 784.8[N]
<u />
In this way we can see that the weight depends on the gravity of where the person is located.
