Answer:
HB = 3.22
Explanation:
The formula to calculate the Brinell Hardness is given as follows:
where,
HB = Brinell Hardness = ?
P = Applied Load in kg = 500 kg
D = Diameter of Indenter in mm = 10 mm
d = Diameter of the indentation in mm = 1.55 mm
Therefore, using these values, we get:
<u>HB = 3.22 </u>
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.
