Test: Volume, Mass, and Density unit 2

A rock displaces 1,500 mL of water. The volume of the rock is:

0.0015 m³

hope you pass

I wish you the best of luck my dudes

The mass of an object is independent of its location.

true

The specific gravity of water is 1.0.

true

The displacement method for measuring volume:

1. is not always accurate 2. may yield incorrect results if the matter is soluble in liquid

The two methods used for determining mass are:

1. measuring directly on a balance 2.calculated by measurements of w and g

A piece of metal has a mass of 200 g and a volume of 2 cm3. What is its specific gravity?

100

An object weighs 55.54 newtons. What is its mass if a gravitometer indicates that g = 9.83 m/s2?

5.65 kg

An object has a mass of 12 kg. On Planet A, the object weighs 69 N. The force of gravity on Planet A is:

5.75 m/s2

In a lab, the mass of object A is 65 kg. Object A weighs:

637 N

If the weather forecaster tells you that the pressure is falling, what is the air density doing?

decreasing

A gas has no volume.

false

The standard metric units of density are:

g/cm3

An equal-arm balance is used to measure:

mass

Density equals:

mass/volume

On the surface of the earth, weight is calculated by:

multiplying mass and gravity

The gravitational force between two objects:

will increase if the objects are moved closer together
