Acoil with an inductance of 2.8 h and a resistance of 12 ω is suddenly connected to an ideal battery with ε = 89 v. at 0.086 s after the connection is made, what is the rate at which (a) energy is being stored in the magnetic field, (b) thermal energy is appearing in the resistance, and (c) energy is being delivered by the battery?

The stored energy is 140.7 watt.

The thermal energy is 62.7 watt.

The delivered energy is 203.4 watt.

Explanation:

Given that,

Inductance = 2.8 H

Resistance = 12 Ω

Potential

Time = 0.086 s

(a). We need to calculate the energy stored in the magnetic field

Using formula of current

Using formula of energy

On differentiating

Again differentiating

Put the value into the formula

(b). We need to calculate the thermal energy

Using formula of thermal energy

Put the value into the formula

(c). We need to calculate the delivered energy by the battery

Using formula of energy

Hence, The stored energy is 140.7 watt.

The thermal energy is 62.7 watt.

The delivered energy is 203.4 watt.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
