Answer: C. The Number of Molecules
Explanation: I just took the test, it's correct.
If your choices are the following:
A. 1-inch IMC.
B. 1-inch rigid conduit.
C. 3/4 inch IMC.
D. 1/2 inch EMT.
Then the answer is C.
The electromagnetic force is attractive for unlike charges and repulsive for like charges
V=abc
a = 2,3cm
b=12,2mm = 1,22cm
c = 0,75inch = 1,905cm
V = 2,3cm*1,22cm*1,905cm ≈ 5,35cm³
Answer:
Density (ρ) = 5 kilogram/cubic meter
Explanation:
Steps:
ρ =
