Answer:
C
Step-by-step explanation:
If you look closely.. You can see that one is longer than the other
I^2 = -1
so,
-99 = -1*99 = i^2*99 = 99i^2
Answer:
1. d=1 2. Y=6
Step-by-step explanation:
Answer:
the density of copper is 90.03g/cm³
Step-by-step explanation:
This problem bothers on the density of a substance, this case for a copper material
Given data
Mass of copper m = 1355g
Volume of copper block v= l*b*h
10*5*3=150cm³
We know that the density
ρ= mass/volume
ρ= 1355/150
ρ= 90.03g/cm²
The density of a substance is defined as the mass of the substance per unit volume
