Electromagnetic waves do not need a material medium for its movement. They all travel at the same speed in a vacuum

What is Electromagnetic waves ?

Electromagnetic waves are those that do not require a material medium for their propagation. They are transverse waves which made up of electric and magnetic waves

In a vacuum all electromagnetic waves have the same speed. That is, all types of electromagnetic waves travel at the same speed in a vacuum which is equal to 299792458 m/s

Examples are;

  • radio wave
  • infrared
  • ultraviolet
  • x - rays
  • Gamma ray
  • visible light
  • microwave

Therefore, in a vacuum, all electromagnetic waves have the same speed.

Rita jeptoo of kenya was the first female finisher in the 110th boston marathon. she ran the first 10.0 km in a time of 0.5689 h
stira [4]

Part a

Answer: 17.58 km/h

Average speed=\frac{Total\hspace{1mm}Distance}{Total\hspace{1mm}Time}

Total Distance =10 km

Total time =0.5689 h

\Rightarrow Average speed=\frac{10\hspace{1mm}km}{0.5689\hspace{1mm}h}=17.6 \hspace{1mm}km/h

Part b

Answer: 17.626 km/h

Average speed=\frac{Total\hspace{1mm}Distance}{Total\hspace{1mm}Time}

Total Distance =42.195 km

Total time =2.3939 h

\Rightarrow Average speed=\frac{42.195\hspace{1mm}km}{2.3939\hspace{1mm}h}=17.626\hspace{1mm}km/h

a light ray traveling in air enters a second medium and its speed slows to 1.71 × 10^8 meters per second. what is the absolute i
givi [52]
The absolute refractive index is equal to the speed of light of the wave in air divided by the speed of light in the second medium. This means that it is equal to 3 x10^8 / 1.71 x10^8. This means the answer is 1.75

A lighthouse is located on a small island 5 km away from the nearest point p on a straight shoreline and its light makes two rev
lisabon 2012 [21]

The distance starting from the point to the lighthouse would be regarded as the hypotenuse.

And also will be the radius of the circle the beam of light is generating at that point. 


So get the radius first

r = sqrt (1^2 + 5^2)

r = 5.099 km


find the circumference:

C = 2*pi * 5.099 km

C = 2 * 16.01898094

C = 32.04 km


Then find the speed in km/sec

One revolution: 60/2 = 30 sec per revolution

Speed = 32.04 km/30 sec

S = 1.068 km/sec is the speed of light

What would cause gravity’s force and why would it?
pickupchik [31]

Answer:

Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. ... You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn't really have an effect on our planet.
