Explanation:
Metallic bonds hold metal atoms and freely moving valence electrons together, while Van der Waals forces hold nonpolar molecules together. OD. Metallic bonds hold metal atoms and freely moving valence electrons together while Van der Waals forces hold atoms together when they share valence electrons.
They will remain parallel because mirrors don't refract light
His atomic theory is pretty fascinating how we never knew that atoms are the smallest non-living thing and it can for any shape or size in water trees and so much more!
Answer:
926 N
Explanation:
Metric unit conversion:
R = 18 cm = 0.18 m
r = 5 cm = 0.05 m
The pressure exerted by the F = 12000N car on the wider arm would be ratio of the gravity over area

The pressure must be the same on the smaller pressure for it to be able to start lifting the car. We can calculate the force f acting on it:
