Explanation:
The gravitational force between the two stars is given by:
where
G is the gravitational constant
m1, m2 are the masses of the two stars
r is the distance between the stars
If the distance is decreased by one-third, it means that the new distance is 2/3 of the previous distance
So the new force will be
So, the force will be 2.25 times the previous value.
Answer:
The answer is
<h2>4 hrs</h2>Explanation:
To find the time taken we use the formula
where
d is the distance covered
v is the velocity
t is the time
From the question
d = 1200 miles
v = 300 mi/hr
We have
We have the final answer as
<h3>4 hrs</h3>Hope this helps you
