Is radiant energy different or like other forms of energy?

Answers

Answer:

It is different!

Explanation:

Radiant energy is a form of electromagnetic energy. It can take the form of visible waves which is what we call light energy or invisible waves such as radio waves or x-rays. As the charges that cause the energy are moving, electrical energy is a form of kinetic energy. Radiant energy moves in a straight line at a very high speed and can be absorbed, transmitted or reflected. Radiant energy is reflected if the object receiving the energy cannot absorb it.

Calculate the total resistance in the circuit below. Express your answer to the nearest tenth.

Answers

The resistance of the given circuit is 12 Ω.

What is resistance?

Resistance is given as the force that decelerates the current flow in the circuit. The resistance can be given in series and parallel connections.

In the given circuit diagram, R2 and R3 are in parallel connections. The resistance of R2 and R3 (R') is given as:

[tex]\rm \dfrac{1}{R'}=\dfrac{1}{R2}\;+\;\dfrac{1}{R3}\\\\ \dfrac{1}{R'}=\dfrac{1}{2}\;+\;\dfrac{1}{6}\\\\\dfrac{1}{R'}= \dfrac{1}{8} \\\\R'=8[/tex]

The R1 resistance is  in series with R2 and R3, thus, the total resistance (R) can be given with:

R = R1 + R'

R = 4 + 8

R = 12

Thus, the resistance of the given circuit is 12 Ω.

Assume that no sliding or slipping occurs between the wheel and the track surface. A. 615 C. .615 B. 6.15 D. 12.3

Answers

The number of revolutions the wheel would make will be 37 revolutions.  The correct option is B.

What is circumference?

The perimeter of the circle is called the circumference of circle.

Given is the wheel diameter CD = Dwheel = 7.45 inches and Length required to cover =144 inches.

For one revolution, distance equal to circumference is moved.

1 rev = π x Dwheel

1 rev = π x 7.45inches

1 rev = 23.393 inches.

No of revolution to travel 540 inches,

= 144/23.393

True or false, electric generators make use of magnetic fields to produce electric current?

Answers

Answer:

True

Explanation:

Magnetic fields can be used to make electricity

Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.

Do generators produce a magnetic field?

An electric motor is a device for transforming electrical energy into mechanical energy; an electric generator does the reverse, using mechanical energy to generate electricity. At the heart of both motors and generators is a wire coil in a magnetic field.
