Answer:
The value is 
Explanation:
The radius is 
The mass of the ordinary matter is 
Generally the speed of the star is mathematically represented as
Here G is the gravitational constant with a value
So
=>
This means it has TWO poles
The 2 poles are NORTH and SOUTH
You would do distance divided by speed. So 150÷3, which would equal 5km per hour.

Answer:
20.25 m
Explanation:
- <u>Centripetal acceleration </u>is given by; the square of the velocity, divided by the radius of the circular path.
That is;
<em><u>ac = v²/r</u></em>
<em> </em><em><u> Where; ac = acceleration, centripetal, m/s², v is the velocity, m/s and r is the radius, m</u></em>
Therefore;
r = v²/ac
= 27²/36
= 20.25 m
Hence the radius is 20.25 meters
