Put these four parts of the electromagnetic spectrum in order from shortest to longest wavelength:
gamma, infrared, microwave, ultraviolet.

Answers

Answer:

gamma, ultraviolet. infrared,  microwave

gamma, ultraviolet. infrared,  microwave are the electromagnetic spectrum.

What is Electromagnetic spectrum?

The range of all EM radiation types is known as the electromagnetic (EM) spectrum.

The visible light from a bulb in your home and radio waves from a radio station are two examples of electromagnetic radiation. Radiation is energy that moves and disperses as it does.

The range of electromagnetic radiation's frequencies, along with their corresponding wavelengths and photon energies, is known as the electromagnetic spectrum.

Microwaves, infrared light, ultraviolet light, X-rays, and gamma rays are the other EM radiation types that make up the electromagnetic spectrum.

Therefore, gamma, ultraviolet. infrared,  microwave are the electromagnetic spectrum.

Determine the magnitude of the tension in the bicep if the barbell force is 450 N.

Answers

The tension in the bicep for the given weight of barbell been supported by the hand is 450 N.

According to Newton's third law of motion, action and reaction are equal and opposite.

When the barbell is held, its weight acts downwards while the force exerted by the bicep pulls the barbell upwards.

A sketch of the force diagram is presented below;

                                                 ↑ Tension in the bicep

                                                 ↑

                                                ⊕

                                                 ↓

                                                 ↓ force of the barbell

Tension in the bicep = force of the barbell

Tension in the bicep = 450 N

Thus, the tension in the bicep for the given weight of barbell been supported by the hand is 450 N.
