Answer:
-200 N
Explanation:
The cabinet moves at constant velocity, so that means there's no acceleration.
Applying Newton's second law to the cabinet:
∑F = ma
F + 200 = 0
F = -200
The friction force is 200 N in the opposite direction.
Answer:
the resistors In series have much power
The speed of the satellite moving in a stable circular orbit about the Earth is 5,916.36 m/s.
<h3>
Speed of the satellite</h3>
v = √GM/r
where;
- M is mass of Earth
- G is universal gravitation constant
- r is distance from center of Earth = Radius of earth + 4930 km
v = √[(6.626 x 10⁻¹¹ x 5.97 x 10²⁴) / ((6371 + 4930) x 10³)]
v = 5,916.36 m/s
Thus, the speed of the satellite moving in a stable circular orbit about the Earth is 5,916.36 m/s.
