The satellite s travels around the earth in a circular path with a constant speed of 20 mm>h. If the acceleration is 2.5 m&gt

Zanzabum

Answer:

The altitude of planet = 5989.198 km

Explanation:

We know that centripetal acceleration, $a = v^2/r$ , where v is the velocity and r is the radius. In this case both acceleration and velocity is given, so we can find radius of satellite.

v = $20 Mm/hr = 20*10^6/3600 = 5555.56 m/s$

a = $2.5 m/s^2$

So, $2.5 = 5555.56^2/r\\ \\ r = 12345698.77 m = 12345.698km$

We have diameter of earth = 12713 km

Radius of earth = 12713/2 = 6356.5 km

The altitude of planet = Radius of planet - radius of earth

= 12345.698 - 6356.5

= 5989.198 km

Which of the following is a characteristic of electromagnetic waves? (2 points)

muminat

Answer:

c They can only travel without a medium.

Explanation:

Electromagnetic waves are made up of electric field and magnetic field.

Here electric field will induce magnetic field and magnetic field will induce electric field.

So this type of field do not require any medium and in vacuum or air the speed of electromagnetic waves are same as speed of light

$c = 3 \times 10^8 m/s$

also we have different range of electromagnetic waves out of which a small range of electromagnetic waves is of visible region in which these waves are visible to us.

so correct answer is

c They can only travel without a medium.
