Asolenoid with 1000 turns has a cross-sectional area of 7.0 cm2 and length of 25 cm. how much energy is stored in the magnetic field of the solenoid when it carries a current of 10.0 a?

The energy stored in the solenoid is 0.18J

Explanation:

We need to obtain the inductance in order to calculate the energy:

The energy stored in the solenoid is given by:

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.

answer: good job it's all correct !
