The moon lacks an atmosphere compared to the Earth. Hope this helps!
Answer:
R = 1.8 m
Explanation:
This is a simple harmonic movement exercise, at the bottom of the swing the acceleration is vertical upwards and the speed is tangential to the trajectory, that is horizontal; the expression for the centralized acceleration is
= v² / R
R = v² /a_{c}
where the radius is equal to the length of the swing
let's calculate
R = 8.1 / 4.5
R = 1.8 m
The same as that of the aircraft that he /she is in. If flying level, it would be zero.
Answer: he goes 1200 m/s
Explanation: because 1 minute is equal to 60 sconds and you have to multiply 20 times 60 so the answer is the car goes 1200 m
The best answer is D) Inertia
Inertia is the word assigned to the Newtonian law of motion that an object in motion tends to stay in motion, in a straight line and in the same direction at the same speed, as long as no other forces are acting on it.
In deep space, there is no air resistance or any other force that would change the ship's velocity, so the law of inertia would keep it moving at the same speed forever.
