In the standing waves experiment, the string has a mass of 31.2 g and a length of 0.7 m. The string is connected to a mechanical
wave generator that produce standing waves with frequency of f. The other end of the string is connected to a mass holder (mholder = 50.0 g) that carries a weight of 5.00x10^2 g. Calculate the linear density of the string.
The mass of an object always stays the same since it is really just the amount of matter in an object so no matter the force applied, as long as the object does not lose or gain matter, the object stays the same
