1. Assume that our asteroid is in the shape of a sphere and that it has a diameter of 2.00 meters and a mass given at 1850 kg.

b. Draw a picture of this spherical asteroid, label the diameter and radius of the asteroid. On your drawing, write the values of mass in kilograms (kg) and grams (g), the diameter and radius in meters (m) and centimeters (cm).

Useful information: 1 kg = 1000 g, 1 m = 100 cm. Remember: the radius of a sphere is equal to half its diameter.

c. Determine the density (in grams per cubic centimeter) of this asteroid. Show all work.

Useful information: Volume of sphere = 4/3 r³.

2. Density comparison and flotation. Explain your answers to the questions below.

a. What is the density of water in grams per cubic centimeter? Is your calculated density of the asteroid greater than, less than, or the same as that of water?

b.. Would you expect this asteroid to float or sink in water based on your calculation and the shape of the asteroid? Explain.

c.If you knew the density of the asteroid but had no information about its shape, would you be able to give the same answer as you gave above? Explain.
