    What tool(s) would you need to use if you are going to make the measurements necessary to calculate the density of a rock? (2 points) balance scale and crucible graduated cylinder and balance crucible and graduated cylinder Which of the following is not an example of potential energy? (2 points) chemical energy gravitational energy mechanical energy nuclear energy for the first one I probably would pick B. And for the second question I thought that all those examples were potential energy. I'm confused :/

    well D=M/V i guess a balance would be necessary to find the mass and a maybe a graduated cylinder to determine how much water the rock displaces to find the volume. not sure tho.

    scale and balance are the same except a balance is more precise

    ohhh, what is a crucible. does it help in finding the density?

    crucible is like tongs to pick up stuff wihtout ur hands

    is it chemical energy?

    I think it might be gravitational

    wikipedia said this: Gravitational energy is potential energy associated with the gravitational field...

    Mechanical energy can be either kinetic energy (energy of motion) or potential energy

    i read the question wrong it says which one is not an example of potential energy my bad

    soooo its probably mechanical energy like you stated

    ahh okay, but I'm still not sure since mechanical is both kinetic and potential
