You have to give me the full sentence or just ask the question better so I can help you
Answer:
Aristole proposed that the Earth was actually round, contractiary of religious beliefs
Explanation:
He believed that the Earth was round and that influenced alot on the way we think about the science of geology.
Answer:
velocity = 7.30 m/sec
23 m depth wave will feel bottom
Explanation:
given data
wavelength = 46 meters
wave period = 6.3 second
to find out
velocity and At what water depth will a deep water wave begin to feel bottom
solution
we get here velocity that is express as
velocity = 
.............1
velocity = 
velocity = 7.30 m/sec
and
wave base = 
× wavelength .................2
wave base = × 46
wave base = 23 m
here water depth more than 23 m will producer will circular wave less than elliptical wave
so 23 m depth wave will feel bottom
Ones like Egypt use resources different because they can be close to the Nile river which provides rich soil for crops and water but people in countries like China use a lot of Bamboo for things since that is commonly grown there
vacuum distillation
Traditionally, the best way of taking salt out of water has been through vacuum distillation. The salt water is enclosed at a low pressure to reduce its boiling point, making it easier to vaporize to separate the salt from the water.
the salt water is heated or the water is allowed to evaporate,the water vapour is collected rather than being lostthe water.vapour is condensed to form pure water/fresh water, salt is left behind and can be used for other purposes.
