You can calculate acceleration with the following equation: Acceleration = (final velocity - starting velocity) ÷ time it takes
Whitepunk [10]

Answer:

1000m/s²

Explanation:

Given parameters:

Initial velocity  = 6000m/s

Final velocity  = 11000m/s

Time  = 50s

Unknown:

Acceleration of the plane  = ?

Solution:

Acceleration is the rate of change of velocity with time:

    Acceleration = (final velocity - starting velocity) ÷ time

Therefore;

      Acceleration  = \frac{11000 - 6000}{5}   = 1000m/s²

ElenaW [278]

Electromagnetic waves travel through a vacuum, Because it has an electric and a magnetic component in it.

<u>Explanation:</u>

The vibration that is created in an electric charge is the cause for the creation of an electromagnetic wave. The electromagnetic waves contains a magnetic and an electric component in it because of this vibration. The transportation of the energy at 3.00 x 108 m/s  speed in an empty space.

The electric and magnetic components that are present in an electromagnetic wave is called fields. There is a vibration at an angle of 90 degree by these fields with respect to the wave motion. The light speed remains unchanged.
