What is the difference between a mechanical wave and an electromagnetic wave

Physics
1 answer:
ivann1987 [24]2 years ago
5 0

Answer:

1. Electromagnetic waves travel in a vacuum whereas mechanical waves do not.

2. The ripples made in a pool of water after a stone is thrown in the middle are an example of mechanical wave. Examples of electromagnetic waves include light and radio signals.

3. Mechanical waves are caused by wave amplitude and not by frequency. Electromagnetic Waves are produced by vibration of the charged particles.

4. While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.

Venus is often called Earth's "twin." Describe TWO ways in which Earth and Venus are similar and TWO ways in which Earth and Ven
insens350 [35]

Venus is called Earth's "Twin" because Earth and Venus have almost the same mass, size, similar composition and they are neighboring planets. Some of most notable differences though between the two planets are their color, temperature, Earth's ability to support life and their atmosphere. Venus' atmosphere is about 100x thicker than Earth's, Earth can support life while Venus can not because Earth has water and plant life and Earth is a bright blue and green while Venus is more orange and red.

When people do a bungee jump theyare asked how much they weigh. Why?​
Katena32 [7]

Answer:

The elasticity of the bungee cord reduces the gravitational forces applied on the body during bungee jumping. For example, if a 100-pound individual jumps from a building and encounters 900 pounds of deceleration force, they will feel 9 "G's" of force.

hopefully this'll help

have a nice day!!! :D

When the formula m*g=F-Fg is used?​
valina [46]

The formula (ma = F - Fg) is used to determine the net upward force acting on a body.

<h3>What is net upward force acting on a body?</h3>

The net upward force acting on a body is the resultant or sum of all the upward forces acting on a body at a given time.

ma = F - Fg

where;

  • F is the applied force
  • Fg is the force of gravity
  • ma is the resultant force

Thus, the formula (ma = F - Fg) is used to determine the net upward force acting on a body.

2. ____________________________ can cause a stationary object to start moving or a moving object to change its speed or directio
Vikentia [17]

As per Newton's law of inertia we can say every object will move in its state of motion either in the state of rest or will move with same constant velocity until some unbalanced external force will act upon it

so here we have to fill the space which says that stationary object can start or moving object will change its direction only in which case

so here the correct answer should be Unbalanced Force condition we will obtain such situation.

so we have

<u>Unbalance force</u> can cause a stationary object to start moving or a moving object to change its speed or direction or both.
