After the initial push, the rock will keep moving forever at constant velocity (constant speed in a straight line)
Explanation:
We can answer this question by using Newton's first law of motion:
"An object at rest (or in motion at constant velocity) will stay at rest (or will keep moving at constant velocity) unless acted upon unbalanced forces" (Law of inertia)
In this problem, we have a rock in a place very far from any force that can act on it. This means that there are no unbalanced force acting on it, so the rock will keep its state of motion forever.
In this situation, the rock is initially thrown by the astronaut. After the initial push, which accelerates the rock up to a certain velocity, there will be no more forces acting on the rock. This means that the rock will continue moving at a constant velocity forever, so at a constant speed in a straight line.

Answer:
solar system is the first blank
Answer:
H=(0,0,2.39)A/m
Explanation:
Ampere's Law for a current filament:
H*(2*pi*R)=I ⇒ H=I/(2*pi*R)
in this case R=y=1; because the current is in the axis x
H=I/(2*pi)=15/(2*pi) A/m=2.39A/m; magnitude
the vector:
to find the direction of the magnetic force H, we uses the right hand rule
H=(0,0,2.39)A/m
The rock moves exactly toward the Northeast, and the two workers are no help to each other. Neither one makes the other one's job any easier.
If the rock has to be moved Northeast and there are two workers available to do the job, then they should both push toward the Northeast.
