Answer:
B) 2.7 g of aluminium has a volume of 1 cm^3
Explanation:
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;

If the density of aluminum is 2.7 g/cm³, it simply means that 2.7 g of aluminium has a volume of 1 cm³
Check:
Given the following data;
Mass = 2.7 grams
Volume = 1 cm³
Substituting into the formula, we have;

Density = 2.7 g/cm³
Answer:B
Explanation:
Galilean transformation are only approximately correct,while Lorentz transformation are more exact
Answer:
T=0.827s
Explanation:
The period of a spring can be calculated with the equation

But we know as well that w is given by,

Replacing,

So we have that

A) reactants interact to form products with different chemical and physical properties
