Allison wants to calculate the denisty of a rock. To do this, what tools will she need to measure the mass and volume of the rock?

Explanation:

Allison can measure the mass of the rock by using a scale. An electronic beam balance will be able to give her the mass of the rock to a fairly accurate degree.

To go about measuring the volume of the rock, an indirect approach has to be adopted since the rock is not regular in shape.  Allison would have to adopt a principle that explains that the volume a solid body displaces when immersed in a pool of liquid, is directly equal to the volume of the solid itself.

This means that if the stone is placed in a beaker of water containing an already measured volume of water, the increase in the volume of the water when the stone is immersed is equivalent to the volume of the stone.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
