Answer:
decrease by a factor 10
Explanation:
The parallax angle of a close star is given by
where
p is the parallax angle
d is the distance of the star from Earth, in parsecs
From the formula we see that the parallax angle is inversely proportional to the distance.
In this problem, the distance of the star is increased by a factor 10:
d' = 10 d
so the new parallax angle would be
So, the parallax angle would decrease by a factor 10.
The force exerted by each team is 30 N. The forces are in the direction opposite to each other.
Force exerted by team 1,
Force exerted by team 2,
Net force,
Therefore, net force on the rope is 0 N.
