The correct answer that would best complete the given statement above would be CARBON DIOXIDE (CO2). Plants <span>depend on the atmosphere for the largest source of carbon dioxide. Carbon dioxide is considered as an important trace gas in the Earth's atmosphere which constitutes about 0.04% of it. Hope this answer helps. </span>
I’m pretty sure it’s, B. An Electric Motor. I apologize in advance if it’s incorrect.
The density of sample is 5 g/cm3
Given:
volume of sample = 20 cm3
mass of sample = 100 grams
To Find:
density of sample
Solution: Density is the measure of how much “stuff” is in a given amount of space. For example, a block of the heavier element lead (Pb) will be denser than the softer, lighter element gold (Au). A block of Styrofoam is less dense than a brick. It is defined as mass per unit volume
density = mass/volume
d = 100/20
d = 5 g/cm3
So, density of sample is 5 g/cm3
