HELP ME PL Clark decides to measure the volume of a rock he found outside. He fills a graduated cylinder with water to 30mL. Places the rock into the water and the water level rises to 37mL. What is the volume of the rock?

The correct answer is - 7 cc or ml.

Explanation:

Given:

The volume of water in a graduated cylinder = 30 mL

The volume of rock = ?

Final volume = 37 ml

Formula:

If an object is placed in water, then the amount of water that is displaced or increased by submerging the object is equal to the volume of the object.

Vi + Vo = Vf

Vi = initial volume

Vo = volume of object

Vf = final volume

Solution:

Placing the values in formula -

30 + Vo = 37

Vo = 37 - 30

Vo = 7 ml or cc.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
