Answer:
It says Error
Step-by-step explanation:
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)

The answer is B. X=1, y=3
This is a working backwards problem. You know he has $35 at the end. Before he gave his brother $5, he would have $40, which is half of what he had before he bought the clothes, so he would have had $80. Before he spent the $40 on shoes, he would have had $120, so the answer is $120.
