Answer:
it takes 365 days to revolve around the star(sun)
C is the answer to your question.
Answer: The velocity is 21.5m/s
Explanation:
Let's call:
M1 and V1 as the mass and velocity of the falcon:
M1 = 1.45kg
V1 = 26.5m/s
M2 and V2 as the mass and velocity of the dove:
M2 = 0.415kg
V2 = 4.35m/s
Where both velocities are positive because both animals move in the same direction.
We can think that the interaction between both animals is a perfectly inelastic collision, because afther the interaction they move as one. Then, we have that the final velocity of both animals togheter is:
V = (V1*M1 + V2*M2)/(M1 + M2)
V = (1.45kg*26.5m/s + 0.415kg*4.35m/s)/(1.45kg + 0.415kg) = 21.5m/s
It looses two protons, it changes from one element to other
