I believe it’s 60km/h
I divided the total distance (120 km) by the time it took to get there (2h) to get this.
Answer:
Half as large.
Explanation:
Using Newton's law of universal gravitation, if the mass of the planet is <em>M</em> and of the Moons 1 and 2 is <em>m</em>, them the force exerted by the planet on them will be:


Which clearly shows that the force that the planet exerts on the Moon 2 is half the force it exerts on the Moon 1.
Answer:
5 N
Explanation:
The bucket is moving at a constant speed of 2m/s Therefore F=ma is 0 N for this to be correct the magnitude of the force exerted by the rope must be equal to the weight of the bucket which is 5 N
To make sure that we have enough resourses to sustain ourselves. You see, if we use up, say, all water on earth, then obviously we won't have any more and we'll die.
