A substance could have physical characteristics and chemical ones too, which are unique to the certain substance.
Color, odor, and how hard the substance, are all examples of physical characteristics of a substance.
Toxicity, flammability, and acidity, are all examples of chemical characteristics of a substance.
There are a couple of things happening while the coaster goes from the top of the hill to the bottom:
- The coaster loses gravitational potential energy.
- The coaster's loss in potential energy becomes its gain in kinetic energy.
- The coaster's gain in kinetic energy causes it to speed up.
- Maybe the coaster is also losing some of its newly gained kinetic energy to friction due to contact between the coaster's internal components and air resistance.
Density can be calculated using the following rule:
Density = mass/volume
We are given that:
mass = 41 grams
volume = 5 cm^3
Substitute with the givens in the above equation to get the density as follows:
Density = 41/5 = 8.2 g/cm^3
Based on the above calculations:
answer : 8.2
units : g/cm^3
Answer:
C sedimentary rocks is the answer.
