All of the four have rings, but if i'm not mistaken Saturn is the only visible ring.
Hope I helped, a brainleist answer would be highly appreciated!
Answer:
The relative velocity of the motorcycle to a passenger in the car is 30 km/h
Explanation:
The question relates to the principle of relative velocity and reference frames
The given parameters are;
The velocity of the motorcycle, v₁ = 120 km/h
The velocity of the car, v₂ = 90 km/h
The relative velocity of an object X with regards to another object Y is the velocity the object X will seem to be moving with to an observer in the rest frame of object Y written as
=
- 
Therefore, the relative velocity of the motorcycle to the car is
= v₁ - v₂, which give;
= 120 km/h - 90 km/h = 30 km/h
The relative velocity of the motorcycle to a passenger in the car = 30 km/h.
F= a*m
F= 0.5 kg * 52m/s^2
F=26kgm/s^2 or 26N
All you have to do is get the culmative effect of the forces by predicting the direction in which each object will move. Just write down what you know and put down questions for your teacher.
