Explanation:
Given
mass of Pendulum M=10 kg
mass of bullet m=5.5 gm
velocity of bullet u
After collision let say velocity is v
conserving momentum we get
Conserving Energy for Pendulum
Kinetic Energy=Potential Energy
here from diagram
therefore
initial velocity in terms of v
For first case
for second case
Therefore
i.e.
Answer:
Explanation:
density of galaxies would be times higher which is equal to 50.81.
It means in a cube that today contains one galaxy the size of the Milky Way, we would instead find 50.81 galaxies this size.
