What is the maximum torque on a 15 what is the maximum torque on a 150-turn square loop of wire 18.0 cm on a side that carries a 50.0-a current in a 1.60-t field?

The maximum torque is 388.8 N-m.

Explanation:

Given that,

Number of turns = 150

Area = 18.0 cm

Current = 50.0 A

Magnetic field = 1.60 T

We need to calculate the maximum torque

Using formula of torque

For maximum value of torque

Put the value into the formula

Hence, The maximum torque is 388.8 N-m.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
