Answer:
Potential energy =mass* acceleration due to gravity * height
mass*acceleration due to gravity =weight
hence potential energy of the puppy= weight * height
=18*2
=36 joule

↪ A satellite was crashed into a comet (on purpose of course)
↪ When it crashed a huge amount of water gushed out
↪ It was over hundreds of thousands of litres
↪ These proved that most of the water came from Comets for the world's first oceans

The combustion of fossil fuels is releasing more co2 into the atmosphere then what would occur naturally
Answer:
lambda = 343 m/s divided by 340 Hz = 1.009 seconds
Hope it helps and have a wonderful day!
Answer:
To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. or v2 = u2 + 2as and this equation of motion can be used to find the final velocity or the distance travelled if the other values are given.
Explanation:
v= u + at
s =( u + v ) t /2
s = ut + at2/2
v2 = u2 + 2as
