Sure what do u need help with
A force over distance is work the unite is joules
(1) Changing Fahrenheit to Celsius:
The formula used to convert from Fahrenheit to Celsius is as follows:
C = <span>(F - 32) * 5/9
</span>We are given that F=200, substitute in the above formula to get the corresponding temperature in Celsius as follows:
C = (200-32) * (5/9) = 93.333334 degrees Celsius
(2) Changing the Fahrenheit to kelvin:
The formula used to convert from Fahrenheit to kelvin is as follows:
K = <span>(F - 32) * 5/9 + 273.15
</span>We are given that F = 200. substitute in the above formula to get the corresponding temperature in kelvin as follows:
K = (200-32)*(5/9) + 273.15 = 366.483334 degrees kelvin
So,
GPE (graviational potential energy) = mass x g x height
GPE is depends on where zero height is defined. In this situation, we define h = 0 as the initial height.
![GPE = 75 \ kg*9.8 \ \frac{m}{s^2}*25 \ m](https://tex.z-dn.net/?f=GPE%20%3D%2075%20%5C%20kg%2A9.8%20%5C%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%2A25%20%5C%20m)
![GPE = 18,375 \frac{kg*m^2}{s^2}](https://tex.z-dn.net/?f=GPE%20%3D%2018%2C375%20%5Cfrac%7Bkg%2Am%5E2%7D%7Bs%5E2%7D)
![GPE = 18,375 \ joules(J) \ or \ 18.375 \ kilojoules(kJ)](https://tex.z-dn.net/?f=GPE%20%3D%2018%2C375%20%5C%20joules%28J%29%20%5C%20or%20%5C%2018.375%20%5C%20kilojoules%28kJ%29)
The builder has gained 18.375 kJ of PE.
