Homework Statement
Ok. here's the deal. since i have started physics, i have been having problems with this concept. when you have an equation that has two sides to it, such as sqroot(F/m/l)=freq(wavelength) and they adjuct one side, how do you know what to do the other side?
For example, the question is "An object is attached to a spring and its frequency of oscillation is measured. Then another object is connected to the first object, and the resulting mass is four times the original value. By what factor is the frequency of oscillation changed?"- the answer is 1/2 but how?!
I keep getting these problems wrong on tests and it seems like everyone gets it except me! PLEASEEEEEE help :(
