Answer:
the gravitational force between the satellite and the planet is 32.4 * 10³N
Explanation:
It is given that,
Mass of the satellite, m = 6500 kg
Speed of the satellite, v = 6.7 × 10³ m/s
distance to the center of the planet = 9 × 10⁶m
Let F is the magnitude of the gravitational force exerted on the satellite by the planet. The centripetal force is equal to the gravitational force. It is equal to :
= 32.4 * 10³N
the gravitational force between the satellite and the planet is 32.4 * 10³N
Answer:
α = 11.05 rad/s^{2}
Explanation:
torque (T) = 2.1 N.m
moment of inertia (I) = 0.19 kg.m^{2}
angular acceleration (α) = ?
from torque = moment of inertia x angular acceleration
2.1 = 0.19 x α
α = 11.05 rad/s^{2}
When we talk about that the sun rises and sets, an individual on the surface of the earth who is motionless or stationary is the spectator or observer. The observer may perhaps be on the moon to see that the sun does not travel all over Earth every 24 hours.
It would be "resonance" that is occurring that causes the nonvibrating tuning fork
