Two satellites have circular orbits with the same radius. One satellite is twice mass of the other. Which has a higher speed?
1 answer:
Answer:
The satellite which has greater mass will have greater orbital speed
As the satellite 1 has greater mass so it has higher speed
Explanation:
We have given satellites have same radius
Let R is the radius of both satellites
Let are the mass of both satellite
Orbital speed is given by
In question it is given
From the relation we can see that orbital speed is directly proportional to the mass
So the satellite which has greater mass will have greater orbital speed
As the satellite 1 has greater mass so it has higher speed

Answer:
Total momentum = 16 Kgm/s
Explanation:
Let the momentum of the two balls be A and B respectively.
Momentum A = 16 kgm/s
Momentum B = 0 kgm/s (since the ball is at rest).
Total momentum = A + B
Total momentum = 16 + 0
Total momentum = 16 Kgm/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
