Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

How to tell if a molecule is polar or nonpolar with electronegativity

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
