A 512 Hz tuning fork is placed over a long tube that is submerged in a column of water. The speed of sound in the air during this experiment is 343 m/s. The tube is place at one position and resonance is heard. It is raised to a new position and resonance is heard. Calculate the distance between the two resonances.

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
