Answer:
one half as large , initial velocity is two times larger
Explanation:
Momentum is conserved.
p₁ + p₂ = p₁' + p₂'
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
m₁ = m₂ =m , v₂= 0
v₁' =v₂'
mv₁ = 2mv₁'
v₁ = 2v₁'
When it rains, the growth aids in the soil drift
Answer:
a small dense nucleus with positive charge and the nucleus is surrounding by orbiting electrons.
Explanation:
An experiment in which alpha particles were used to bombard thin sheets of gold foil led to the conclusion that an atom is composed mostly of a small dense nucleus with positive charge and the nucleus is surrounding by orbiting electrons.
Answer:
Explanation:
Given:
- the voltage of the source,
- distance of separation between the capacitor plates,
- energy of the capacitor,
Assuming that there is free space between the plates, so the permittivity, 
<u>We have the energy stored in a capacitor as:</u>
