Answer:
Option A
interpreting results
Explanation:
In a Scientific research, we first formulate and test hypothesis of the study. A hypothesis is a tentative guess in the study which should be validated in the process of the study. We may have a null and alternative hypothesis. After formulating the study, we conduct the actual study where we get raw data. The raw data is then analyzed, in many cases using statistical analysis tools such as R, python, excel spreadsheet etc. Therefore, the next step after formulating and objectively testing hypotheses is to interpret the results.
Answer:
is the innermost layer,
has the highest air pressure
Explanation:
The troposphere is the lowest layer of Earth's atmosphere and site of all weather on Earth. The troposphere is bonded on the top by a layer of air called the tropopause, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth.
So many thinks the water wouldnt have as many waves it could result in no season and even an ice age. Nights would be darker. In result in the tides changing animals will be confused, some species rely on the tides for food and shelter. So without that it would cause a chain of mass extinction.
Answer:
Explanation:
Given:
- flow rate of water,
<em>∵Density of water is 1 kg per liter</em>
∴mass flow rate of water, 
- height of pumping,
- efficiency of motor drive,
- diameter of pipe,
<u>Now the power required for pumping the water at given conditions:</u>
<u>Hence the electric power required:</u>
<u>Flow velocity is given as:</u>
where: a = cross sectional area of flow through the pipe
