The speed of the satellite is v = √(Gmp/r)
At the geostationary orbit, the gravitational force of attraction of the planet on the satellite equals the centripetal force on the satellite.
Let F = gravitational force
where G = universal gravitational constant, mp = mass of the planet, m = mass of satellite and r = radius of geostationary orbit.
Also, the centripetal force F'
where m = mass of satellite, v = speed of satellite and r = radius of geostationary orbit.
Since both forces are equal,
F = F'
So, the speed of the satellite is v = √(Gmp/r)

Total play = 20
Nancy win = 12
Ratio would be: 12/20 = 6/10 = 3/5
So, your answer is 3/5
The Value of X is 10.
KhanAcademy.org has some great explanation videos on their website and they have a YouTube channel.
Here is an explanation for the answer.
Answer:
Step-by-step explanation:
- Total number of plants = 15
- Total cost = $96
- Cost of pink flowering plant = $8
- Cost of purple flowering plant = $5
<u>Let x and y be the number of plants bought. Then we have equations:</u>
- 8x + 5y = 96
- x + y = 15 ⇒ y = 15 - x
<u>Substituting y in the first equation:</u>
- 8x + 5y = 96
- 8x + 5(15 - x) = 96
- 8x + 75 - 5x = 96
- 3x = 96 - 75
- 3x = 21
- x = 7
Correct option is the second one
Because sine15. 7°=h/2500
=2500×sine15.7°=h
=676 km
this how you will get h
