Answer:
Explanation:
Given
Total volume of tank ![V=60\ L\approx 60\times 10^{-3}\ m^3](https://tex.z-dn.net/?f=V%3D60%5C%20L%5Capprox%2060%5Ctimes%2010%5E%7B-3%7D%5C%20m%5E3)
Suppose a is the side of cubical tank
volume of cubical tank ![a^3](https://tex.z-dn.net/?f=a%5E3)
![a^3=60\times 10^{-3}](https://tex.z-dn.net/?f=a%5E3%3D60%5Ctimes%2010%5E%7B-3%7D)
![a=3.909\times 10^{-1}\ m](https://tex.z-dn.net/?f=a%3D3.909%5Ctimes%2010%5E%7B-1%7D%5C%20m)
![a=0.39\ m](https://tex.z-dn.net/?f=a%3D0.39%5C%20m)
As the water boils at a certain temperature, phase change happen without change in its temperature. The heat associated is called the latent heat of vaporization. We obtain the heat required by multiplying the mass of the water to the latent heat of vaporization.
Heat = 0.018 x <span>2.3 x 10000000 = 41400 J</span>
Solar energy is one of the renewable energy sources that is invested around the world because of its large potential. the sun as a free source can sometimes bring a drawback. one of the drawbacks is that it cannot be harnessed when storms or rains are present in the weather. it is also expensive and young.
The power developed by the student is 756.9 J/s and remains the same if the student takes the same time to climb the stairs when climbing it in two's and three's.
<h3>What is power?</h3>
Power is the rate at work is done.
- Power = work done/time
- work done = mass × acceleration due to gravity × height
Work done = 65.5 × 10 × (18 × 0.165) = 1945.35 J
Power = 1945.35/2.57 = 756.9 J/s
If the student climbed the steps in two or three at a time, the power does not change if the time remains the same.
- Time required = Energy/ power
The time required to convert the Big Mac meal from McDonalds = 4 853 440/756.9
Time required = 6412.26 seconds
Therefore, from the power developed by the student, it will take him 6412.26 seconds to convert all the energy in a Big Mac meal.
