This is a chemical reaction.
VOLUME= 5cm*10cm*2cm =100cm^3
but density of iron=7.874g/cm^3
mass=7.874g*100 =787.4g
mass of that block = 787.4g
The correct option is C.
The density of an object refers to its mass per volume. Water and ice have different densities. The differences in their densities is due to the empty spaces which exist in the structure of ice. Because of the empty spaces, the structure of ice occupy more volume than that of water, hence it is less dense than water.
There are nine essential amino acids for humans (histadine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine) that must come from your … food.
These artificial homes preserve the resources in the animal's environment and increases population size.
<h3>What is Population size?</h3>
This is defined as the number of organisms in a population at a given place and time.
Since the resources used are artificial, they are preserved with an increase in the population due to reproduction.
