Astraightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. what is the density of a 333-g rock that displaces 51 cm3 of water? (note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on archimedes’ principle.)

The density of the object will be 6.53 g/ml.

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of rock = 333 grams

volume of rock = Volume of water displaced = = 51 ml

Putting in the values we get:

Thus density of the rock will be 6.53 g/ml

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.
