Finding the density of solids requires a method of measuring the volume of the solid. If the solid has a regular geometric shape, the volume can be calculated from a measurement of the dimensions of the shape. Consider the Object B below. Given that its mass is 108.510 g and its dimensions are: diameter = 2.90 cm, height = 3.20 cm, what is the density of Object B (cylinder)?

Explanation:

volume of cylinder is equal to A(area )h( height)

so 2.90*3×3.20=78cm*3

mass equal to 108.510g

so the density is

108.510/78=1.4g/cm/3

distance, luminosity, brightness, radius, chemical composition, and temperature

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
