Answer:
10 m/s
Explanation:
Momentum before collision = momentum after collision
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(8 kg)(8 m/s) + (6 kg)(6 m/s) = (8 kg)(5 m/s) + (6 kg) v
64 kg m/s + 36 kg m/s = 40 kg m/s + (6 kg) v
60 kg m/s = (6 kg) v
v = 10 m/s
This is not that exact but I hope that this will help you.
The effect of gravity is more in liquid than in solid because as we know that liquid pressure increase in the increase in depth but solid dont
Answer:
C. Electric energy
Explanation:
A generator is designed to convert chemical energy to mechanical energy and them electrical energy.
- It is an alternate source of electricity for most homes and industrial establishments.
- The source of energy for the generator is a fuel usually fossil fuels.
- This energy source is ignited and it produces heat energy which drives the motion of the pistons in the set.
- As the piston moves, an magnetic field is cut through by a conducting wire.
- This inducts the production of currents.
