Intramolecular and intermolecular forces hold together which of the following? A. atoms within a molecule B. molecules within an object C. charged particles within a salt crystal D. the atoms within compounds E. all of the above

A technician builds an RLC series circuit which includes an AC source that operates at a fixed frequency and voltage. At the operating frequency, the resistance R is equal to the inductive reactance XL.

How are the mass and weight of an object related? Weight equals mass plus the acceleration due to gravity. Mass equals weight multiplied by the acceleration due to gravity. Mass and weight are the same.
