Agraduated cylinder contains 20.0 ml of water. after a rock is placed in the cylinder, the level rises as shown below. what is the volume of the rock? rock in cylinder a. 14 cm3 b. 22 cm3 c. 34 cm3 d. 38 cm3

A.

Explanation:

According to the Archimedes' Principle:

A body totally or partially immersed in a fluid at rest, experiences a vertical upward thrust equal to the mass weight of the body volume that is displaced.

In this case the fluid is water. So, the rock, being more dense, will weigh more than water and therefore will displace water that will make the water level in the cylinder to ascend.

Therefore, if we have an initial volume and after the rock was placed the water level rised to (which is the volume displaced by the rock).

We can find the volume of the rock by the following equation:

Then:

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
