Answer:
The sun looks bigger than other stars because it is closer to the Earth, distance makes it look larger
Answer
given,
mass of satellite = 545 Kg
R = 6.4 x 10⁶ m
H = 2 x 6.4 x 10⁶ m
Mass of earth = 5.972 x 10²⁴ Kg
height above earth is equal to earth's mean radius
a) satellite's orbital velocity
centripetal force acting on satellite = 
gravitational force = 
equating both the above equation



v = 5578.5 m/s
b) 


T = 14416.92 s

T = 4 hr
c) gravitational force acting


F = 5202 N
1. 2500/60 joules/sec
2. 2,500Nm
The equation is
s= d/t
In this case you would have to write it out as:
s= 20/5
Speed = 4
Answer:
5m
Explanation:
because if the driver jamed the brakes at 20m and stop at 15m the it took the driver 5m to fully stop
