when electric power is transmitted over long distance, line losses can be reduced by generating AC rather than DC voltage and by
1 answer:
When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.
<h3>What is electric power?</h3>The complete question is attached to the image below.
The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.
The AC transmitted is of high voltage, and the power is low. The equation for current is given,
P = VI
The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.
Therefore, the loss is reduced by transferring high voltage and, low current AC.

Answer:
The weight should be added to the base of the sign to keep it from tipping is 65.6 lb
Explanation:
Given data:
A sigh weighs 40 pounds
Suported by an 18 in x 18 in square
Force of the wind 13.2 lb
Questions: Will the sign tip over, if yes, how much evelnly distributed weight should be added to the base of the sign to keep it from tipping, W = ?
The sign and the post have a length of 6 ft. You need to calculate the distance from the edge to the middle point:
18/2 = 9 in = 0.75 ft
Force acting in the base (40 lb):
The weight should be added to the base:
