This question is worth 54 points ! rock falls from a ledge to the ground what energy conversion occurs during this process a potential to kinetic b kinetic to potential c thermal to mechanical d chemical to mechanical

A. potential to kinetic

When the rock was ready to fall off the ledge with energy building up (potential energy), it started falling off the ledge. (kinetic).

Thermal energy comes from heat, generating movement. (No heat in this scenario)

Mechanical energy comes from the sum of kinetic and potential energy in an object that is used to do work. (Like a wrecking ball, not in this case though, because the rock came from stop, to motion, to finish).

Hope this helps :) Brainliest?

A. Potential to kinetic because at first it was resting and then it was moving

Explanation:

Potential energy is converted into kinetic energy. I am 100% positive.

Photosynthesis is the procedure of changing sunshine in chemic muscularity simply by keeping that in the bonds regarding glucose or refined sugar. This happens in crops, bacterias plus some protists, or maybe alga to produce refined sugar because foods. Your chlorophyll contained in simply leaves involving photosynthetic plant life reflects power from sunlight and changes it to help carbohydrates. Photosynthesis uses co2 fractional laser (CO2) along with mineral water because raw material to provide mister and relieve oxygen like a by-product.
