200g*1 mole/ 18g=11.1 moles There are 11.1 moles of water.
<u>Answer:</u>
Ball will move 92.8125 meter along the cliff in 7.5 seconds.
<u>Explanation:</u>
We have equation of motion ,
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this case initial velocity = 0 m/s, acceleration = 3.3
, we need to calculate displacement when time = 7.5 seconds.
Substituting

So ball will move 92.8125 meter along the cliff in 7.5 seconds.
It is a solid when is frozen and a liquid when it melts
Answer:
Accelerating charges.
Explanation:
Electromagnetic waves are waves produced by the vibration of both electrical and magnetic fields.
This interaction produces an energy source that does not require any medium to propagate.
To produce electromagnetic waves, electric and magnetic fields must be vibrating.
An electric charge produced when vibrating under voltage will produce electromagnetic waves. This is the same for all sources of these waves.
The sun produces electromagnetic waves. A lot of human activities also does this.
Answer:
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
