Explanation:
It is given that,
Relativistic Mass of the stone, m₀ = 0.6
Mass, 
Relativistic mass is given by :
.........(1)
Where
c is the speed of light
On rearranging equation (1) we get :
v = 0.61378 c
or
v = 0.6138 c
So, the correct option is (c). Hence, this is the required solution.
Answer:
Time period is directly proportional to the length so if the length is doubled the time period is doubled

Answer:
D)
Explanation:
The Period-Luminosity relationship tells us that luminosity increases with the period, and of course the more luminosity a star has the more far away they can be seen, so from this we know that:
A) False since lower luminosities can be observed when they are close.
B) False since longer periods means higher luminosities
C) False since lower luminosities can be observed when they are close.
D) True: Variable stars with shorter periods have lower luminosities, so they can only be observed when they are close.
