The density of balsa wood is 0.170 g/cm3.  What is the mass if the volume is 12.0 mL?

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

density = 0.17 g/cm³

1 mL = 1 cm³

12 mL = 12 cm³

So we have

mass = 0.17 × 12

We have the final answer as

Hope this helps you

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

i think its c if i'm wrong
