Answer:

As explained below.

Explanation:

The sun rays reach the earth's surface at an angle of 90 degrees at the equator which is direct and is short as compared to the poles it's long and about 66.5 degrees to the south and north. In the tropics its falls as 23.5 degrees in the northern and southern hemisphere.

The sun rays that form a tangent to the northern hemisphere are at 0, 23.5, 66.5 degrees i.e tropics, temperate and poles. And same is for the southern hemisphere.

On June 21 the southern hemisphere has winter seasons as the amount of insolation that reaches the southern side is less due to the tilt of the sun.

Answer: Turn off unnecessary lights in the house and try not to waste energy

Explanation: I would most definitely try not to waste energy and electricity by keeping things like lights that don't need to be on, turning them off, unplugging things when I'm not using them, like a tv, a toaster, fans, printers and other appliances that don't need to be plugged in when not being used. This helps save energy in return.

hope this helps in some way.

A satellite orbiting earth has a tangential velocity of 5000 m/s. earth’s mass is kg and its radius is m. which is the distance

inessss [21]

The distance of the satellite form the earth is:
9,608,000 m (Option C) in Standard form, this is written as 9.6 x 10 $^{6}$ .

<h3>What is an Orbiting Satellite?</h3>

An Orbiting Satellite is a satellite that goes around the earth in an elliptical path known as an orbit.

To calculate the distance of the satellite from the earth we must equalize the force of Gravity to Centripetal Force given that these are the two forces that are at play here.

Step 1:

Equation that equalizes Gravity to Centripetality is:

G = mM/r² = m(v²/r)

Note that G = 6.67 x 10 $^{-11}$ (This is a gravitational constant.)

m is the Mass of the Satellite

M is Mass of the Earth

r is the distance of the satellite from the center of the earth

v is the satellites tangential velocity

Step 2 - Rearrange the formula and substitute the numbers above to get r

r = G (m/v²) = (6.67 x 10 $^{-11}$ ) (6 x10 $^{24}$ /5000²) =

= 1.6 x 10 $^{7}$ m

Recall that form our postulation above, this is the satellites distance form the center of the earth.

To get it's distance form the earth's surface, we must know remove the value of the radius of the earth from the calculation. Where radius of the earth is given a r'

Hence,

r' = r - R = 1.6 x 10 $^{7}$ m - 6.4 x 10 $^{6}$ m

= 9.6 x $10^{6}$ m or 9,608,000 m
