The answer is <em>C.) Elevated</em>
Answer:
The claim is not reasonable
Explanation:
From the question we are told that
The power consumed is
The height of the pool's free surface is
The rate is
Given that the rate is 53 liters in 1 second , let say the 1 liter is equivalent to 1 kg so 50 liter = 50 kg
So the workdone by the pump is mathematically represented as
=>
=>
So what this value is telling us is that 14700 J of work is done in one second
and generally power is workdone per time thus the power consumed to move water at the given rate is 14.7 kW which is far greater than the power stated in the question so the claim is not reasonable
Answer:
Explanation:
<u>Temperature Scales
</u>
There are three temperature scales in the modern sciences: Fahrenheit, Celsius, and Kelvin. Fahrenheit temperature scale assigns the value 32 for the freezing point of water and 212 for the boiling point of water and divides that interval into 180 parts. Celsius scale has a similar reference, giving 0 to the freezing point of water and 100 for the boiling point of water. The conversion between them is as follows
The coldest temperature yet measured on the surface of any body in the solar system is -235°C. Converting to Fahrenheit
D) decreasing temperature and increasing luminosity indicates a stellar evolution. This answer based on the axes of the Hertzsprung-Russell Diagram which describe the stellar evolution trend<span>. The X axis in the diagram indicates the decreasing of star's temperature. The Y axis in the diagram indicates the increasing of star's luminosity.</span>
