Answer:
First law of thermodynamic state that energy is always conserved, in other word, energy cannot be created or destroyed.
This means that energy can only transfer from one source to another.
For example, the electricity we used to power our phone didn't come from nowhere.
We charge our phone using the energy from the electricity from the outlet.
The outlet gets its energy from the power plant, who generated that energy from burning coal.
The coal they burned got their energy while they were alive as plants.
The plants got their energy from the sun.
The sun got its energy from other cosmic stuff and so on...
My point is that the energy we use will always cycle around. It doesn't come from thin air and it doesn't disappear into thin air either. This help keeps things balance because if energy is created out of thin air then the earth might just blow up. If energy gets erased into thin air then there'll be nothing to fuel life.
Answer:
The pressure in the water is 
Explanation:
Given that,
Depth = 101 m
Let P be the pressure at the bottom of water at a depth
We need to calculate the pressure in water
Using formula of pressure
Where, 
= atmospheric pressure
= pressure in water
Put the value of in to the formula
Put the value into the formula
Hence, The pressure in the water is
Answer:
All the planets have nearly circular orbit except the Pluto
Explanation:
Planets closer to the Sun move around their orbits at a very high speed than planets farther from the Sun.
All the planets except Pluto, orbit the Sun in nearly the same plane.
All the planets have nearly circular orbits except Pluto because of it's distance from the sun which is over 5,000,000,000km
