Identify the primary form of energy in each image. 1. chemical potential energy 2. radiant energy 3. motion energy

candle light - radiant energy

clouds/wind - motion energy

log of wood - chemical potential energy

Explanation:

A burning candle produces heat and light which is electromagnetic radiation. It can travel in space. Thus, the primary form of energy of this image is the radiant energy.

In the second image, the clouds are in motion as the wind is blowing. The energy possessed by it is the motion energy. This motion energy can be harnessed to produce electrical energy using wind mills.

In the last image, the log of wood is kept still. It contains chemical potential energy which is due to the bonds between molecules of the wood. when the wood is burnt, these bonds are broken and stored chemical potential energy converts to heat and light energy.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

no

sodium is solid at rt
