Which one of the following statement is TRUE?

In the cables, the location of fault is usually found out by comparing the capacitances of insulated conductors.

The wind speed increases with height because of

Wind speed increases as the height from the ground increases mainly due to the decrease in the friction produced by land terrain.

A given solar cell has the following specifications:
Open-circuit voltage, Voc: 0.7 V
Short-circuit current, Isc: 3 A
Voltage at maximum power, Vmp: 0.5 V
Current at maximum power, Imp : 2.65 A
Calculate the fill factor.

Where,
Pmp is maximum power in watt
Vmp maximum voltage at maximum power in volt
Imp is maximum current at maximum power in ampere
Voc open circuit voltage in volt
Isc is short circuit current in ampere

Fill Factor = Pmp/(Vosc*Isc) = (Vmp*Imp)/(Voc*Isc)
= (2.65*0.5)/(0.7*3)
= 0.63
