Answer:
The period of the satellite is 12.05 s.
Explanation:
The period of the satellite can be determined by;
T = 
where: T is the period, r is the radius of the orbit, G is the gravitation constant and M is the mass of the Earth.
Given that: r = 6 x (6.38 x
) = 38.28 x
m, M = 5.98 x
kg, G = 6.673 x
N
/
.
Therefore,
T = 
= 
= 
= 12.0463
T = 12.05 s
The period of the satellite is 12.05 s.
Answer:
rev/s
Explanation:
= mass attached to each hand = 5 kg
= initial distance of masses in each hand = 1 m
= final distance of masses in each hand = 0.1 m
= moment of inertia of body = 5 kgm²
= initial total moment of inertia =
= initial angular velocity = 1 rev/s
= final total moment of inertia =
= final angular velocity = ?
Using conservation of angular momentum



rev/s
F n = ma / unbalanced force - In the direction of the force.
A the entropy of the reaction I think ion know if that’s correct
Velocity is a vector quantity i.e. it has both magnitude and direction
Speed is a scalar quantity i.e. it has only magnitude
