8 0


1. Electromagnetic waves travel with a constant velocity in vacuum . The velocity is approximately 186,000 miles per second or 300, 000 km per sec, the same as the speed of light.

2.Electromagnetic waves are not deflected  by electric or magnetic fields

3. Electromagnetic waves can show interference or diffraction

4. Electromagnetic waves are transverse waves, similar to water waves in the ocean or the waves seen on a guitar string. 

5. Electromagnetic waves may be polarized.

6. Electromagnetic waves need no medium  of propagation.

bogdanovich [222]

Answer:

One year

Explanation:

In Florida, once you have had your learner's license for 1 year without any traffic convictions, you will receive an intermediate license.

The rule for Florida is that if a driver drives safely without any conviction during that year of his trial, he will receive an intermediate license. This means that he is now completely eligible and safe to drive around Florida's roads.

I hope the answer is helpful.

Thanks for asking.

What is the exact meaning of croos section and cross sectional area of a conductor?
Sonbull [250]
The cross section is the little tiny circle you see when you cut a wire
and look at the flat, cut end.

The cross-sectional area of the wire is the area of that little circle. 
It's equal to

                           Area = (pi) x (1/4) x (Diameter of the wire)²

A car has a mass of 975 kg. by pushing on the car, evan increses its speed from 0.5 m/s to 3 m/s. what impulse did evan apply to
jarptica [38.1K]
Impulse = change in momentum = F x dt
Where F is sufficiently large and dt is very small(tending to zero).

Therefore impulse = mass x final velocity - mass x initial velocity
                                = 975 x 3 - 975 x 0.5
                                = 2437.5 Kg-m/s. 
Hence option C is correct.
