3. A satellite orbiting the Earth has an orbital radius of 2.50x10 m. Calculate its speed in orbit. Given:
r=
M=5.97 x 10^24 kg (planet Earth's mass)
G=6.67 x (10^- 11) N. m/(kg 2)
Unknown:
v=?
Equation:
v=square root (GM/T)

(IT IS NOT A Multiple choice question)

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

How is the acceleration of an object in uniform circular motion constant? a - in magnitude only b - in direction only c - in both magnitude and direction d - in magnitude, direction & orientation
