WebFeb 27, 2024 · To calculate the gravitational potential energy, follow these easy steps: Find the value of the gravitational acceleration at the reference point. On Earth's surface, you can use g = 9.81 m/s². Multiply the mass of the object ( m) and the height above the reference level ( h) by the acceleration g to find the potential energy: E = m · g · h. WebAug 2, 2024 · Solution. The question gives us the heat, the final and initial temperatures, and the mass of the sample. The value of ΔT is as follows:. ΔT = T final − T initial = 22.0°C − 97.5°C = −75.5°C. If the sample gives off 71.7 cal, it loses energy (as heat), so the value of heat is written as a negative number, −71.7 cal. Substitute the known values into heat = …

WebApr 7, 2024 · Plug in the known variables and solve. Once you have rearranged the equation, you can solve for the wavelength by plugging in the variables for energy. Because the other two variables are constants, they are always the same. To solve, multiply the constants together and then divide by the energy.
