The earth remains in orbit around the sun due to the force of gravity. How does the force of gravity exerted by the sun on the e
2 answers:
Answer:
The force remains same.
Explanation:
Let the mass of sun is M and the mass of earth is m. The distance between them is d.
According to the Newton's law of gravitation, the force between the two bodies is directly proportional to the product of their masses and inversely proportional to the square of distance between them.
Thus, the force exerted by the sun on earth is equal to the force exerted by the earth on sun are same which is given by

Answer:
The inlet velocity is 21.9 m/s.
The mass flow rate at reach exit is 1.7 kg/s.
Explanation:
Given that,
Mass flow rate = 2 kg/s
Diameter of inlet pipe = 5.2 cm
Fifteen percent of the flow leaves through location (2) and the remainder leaves at (3)
The mass flow rate is
We need to calculate the mass flow rate at reach exit
Using formula of mass
We need to calculate the inlet velocity
Using formula of velocity
Put the value into the formula
Hence, The inlet velocity is 21.9 m/s.
The mass flow rate at reach exit is 1.7 kg/s.
