Radiant energy travels in the form of electromagnetic waves. They are called electromagnetic waves because they contain both an electrical field and a magnetic field. Radio waves and light waves are examples of electromagnetic waves. Unlike mechanical waves such as sound, electromagnetic waves can travel in space. Which statement describes how electromagnetic waves and sound waves are alike?




Both types of waves are mechanical waves


Both types of waves transfer energy


Both types of waves can travel in space


Both types of waves have an electrical and magnetic field

Answers

Answer 1

Answer:

It is the third option.

Explanation:

Answer 2

Both electromagnetic waves and  mechanical waves transfer energy.

What is electromagnetic waves?

In a vacuum, or free space, electromagnetic waves are self-sustaining oscillations of the electric and magnetic fields.

An essential fundamental constant with the value of 3×10⁸m/s. . is the velocity of electromagnetic waves in vacuum or free space.

Diffraction, refraction , and polarization is possible in electromagnetic waves.

Like other waves, electromagnetic waves carry motion and energy.

What is  mechanical waves?

An oscillation of matter known as a mechanical wave is what is responsible for the transmission of energy via a medium.

The transmission medium sets a restriction on how far a wave can travel. In this instance, there is almost little translational motion and the oscillating material rotates around a fixed point. The measurement of mechanical waves, which is determined by displacement divided by wavelength, is one intriguing aspect of them.

Hence, both types of waves transfer energy.

A 62 kg wake boarder is being pulled by a boat with a force of 124 N. What is the acceleration of the wake boarder?

Answers

Answer: 2m/s

Explanation:

The acceleration of the wake boarder is equal to 2 m/s².

What is acceleration?

Acceleration of a body can be described as the change in velocity of a body with respect to time. The acceleration is a vector parameter posses both magnitude and direction. Acceleration is described as as the second derivative of position w.r.t. time and the first derivative of the velocity of an object w.r.t. time.

According to Newton's 2nd law of motion, the force (F) acting is equal to the product of the mass and acceleration (a).

F = ma

or,   a = F/m

Therefore, acceleration (a) is inversely proportional to the mass (m).

Given, the force with which the boat pulled wake boarder, F = 124 N

The mass of the wake boarder = 62 Kg

The acceleration of the wake boarder, a = 124/62 = 2 m/s²

Therefore, the acceleration of the wake boarder is 2 m/s².
