Why is angular velocity negative?
Why is angular velocity negative? First definition Angular velocity is positive when the rotation is counterclockwise and negative when it is clockwise. Second definition: Angular velocity is positive when the angular displacement is increasing and negative when the angular displacement is decreasing. Does radius affect angular velocity? Linear/tangential velocity, in a circlular path, increases with […]
Does HCN have a dipole moment?
Does HCN have a dipole moment? (d) HCN is a linear molecule; it does have a permanent dipole moment; it does contain N, however the nitrogen is not directly bonded to a hydrogen. Therefore dispersion forces and dipole-dipole forces act between pairs of HCN molecules. Is HCN a strong acid? Strong acids are 100% ionized […]

What is meant by order of magnitude?
What is meant by order of magnitude? Orders of magnitude are used to make approximate comparisons. If numbers differ by one order of magnitude, x is about ten times different in quantity than y. If values differ by two orders of magnitude, they differ by a factor of about 100. How many seconds are present […]
