Answer:
A
Explanation:
Begin as protostars, which fire up when they collapse and become denser and hotter.
Velocity (unit:m/s) of the wave is given with the formula:
v=f∧,
where f is the frequency which tells us how many waves are passing a point per second (unit: Hz) and ∧ is the wavelength, which tells us the length of those waves in metres (unit:m)
f=1/T , where T is the period of the wave.
In our case: f=1/3
∧=v/f=24m/s/1/3=24*3=72m
Answer:
the answer for the question is the last option
Answer:
So the mass of the second object M will be 1.951 kg
Explanation:
We have given mass of the first object 
and its velocity 
Mass of the second object 
it is at rest so its velocity 
From conservation of momentum we know that
Initial momentum = final momentum
So 
M = 1.951 kg
