If the star Alpha Centauri were moved to a distance 10 times farther than it is now, its parallax angle would
7nadin3 [17]

Answer:

decrease by a factor 10

Explanation:

The parallax angle of a close star is given by

p=\frac{1}{d}

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

p'=\frac{1}{10 d}=\frac{1}{10}\frac{1}{d}=\frac{p}{10}

So, the parallax angle would decrease by a factor 10.

In a tug of war, two teams exerts a force of 30 N each. What is the net force acting on the rope?
Arte-miy333 [17]

The force exerted by each team is 30 N. The forces are in the direction opposite to each other.

Force exerted by team 1, F_{1}=30 N

Force exerted by team 2,F_{2}=-30 N

Net force, F=F_{1} +F_{2}

=30+(-30)=0

Therefore, net force on the rope is 0 N.
