Answer:

Explanation:

Given: 1 dietary Calorie = 1000 calories

           1 calorie = 4.184 Joules

But,

1 dietary Calorie = 1 Kcalorie

                           = 1000 x 4.184 Joules

                           = 4184 Joules

                           = 4.184 KJoules

1 dietary Calories contains 4.184 KJ of energy.

A bottle of Coca cola contains 42 Kcalories; thus,

1 Kcalorie = 1000 calories

                = 4.184 KJoules

Energy = 42 x 1 dietary Calories

            = 42 x 4.184 KJoules

            = 175.728 KJoules

Energy ≅ 176 KJ

So that;

In my bottle of coca cola, there are 176 KJ of energy.

If the magnetic energy stored by a 0.50 H inductor is 3.6 J, what is the current through it?
finlep [7]

The current passing through the inductor is 3.8 A. The correct option is D. 3.8 A

<h3>Energy stored in a magnetic field </h3>

From the question, we are to determine the current passing through the inductor.

From the formula, for the energy stored in a magnetic field

E = 1/2LI²

Where E is the energy

L is the inductance

and I is the current

From the given information,

E = 3.6 J

L = 0.50 H

Putting the parameters into the formula, we get

3.6 = 1/2 × 0.50 × I²

3.6 = 0.25 × I²

I² = 3.6 ÷ 0.25

I² = 14.4

I = √14.4

I = 3.7947

I ≅ 3.8 A

Hence, the current passing through the inductor is 3.8 A. The correct option is D. 3.8 A
