Answer: 
Explanation:
We are told both planets describe a circular orbit around the star S. So, let's approach this problem begining with the angular velocity
of the planet P1 with a period
:
(1)
Where:
is the velocity of planet P1
is the radius of the orbit of planet P1
Finding
:
(2)
(3)
(4)
On the other hand, we know the gravitational force
between the star S with mass
and the planet P1 with mass
is:
(5)
Where
is the Gravitational Constant and its value is 
In addition, the centripetal force
exerted on the planet is:
(6)
Assuming this system is in equilibrium:
(7)
Substituting (5) and (6) in (7):
(8)
Finding
:
(9)
(10)
Finally:
(11) This is the mass of the star S
Answer:
0.5
Explanation:
calculating the total resistance for the both the parallel and the series resistors then later using the ohm's law formulae V=IR to calculate current.
It is because change in the Mass of the object balances the change in the Volume of the object equally...........
Answer:
coronal mass ejection
Explanation:
Solar wind is something that has to do with magnetism,
CME is " is a significant release of plasma and accompanying magnetic field from the solar corona," that often follows solar flares.
