2. An experiment is performed to measure the spring force constant (k) of an unknown spring. When a 100g +/- 1g mass (m) is hung from the spring stretches a length (x) 5cm+/-0.2cm. Based on these measurements, what is the uncertainty in the k? Suppose the experiment had been done with a 300g +/-1g mass. How would this affect (if at all) the uncertainty in k due to the stretch? How would this affect (if at all) the uncertainty in...

nalysis: Your lab report should include the following: In the "Calculations" section: 1. Using your measurements of the dimensions of the room, calculate lume of the room. Also calculate the uncertainty in the volume given your estimated uncertainties in the length, width and height. 2. Determine the area of the table for both sets of measurements (ruler and meter stick), and calculate the uncertainty in the area using both sets...

3) In lab 11, you found the relationship between the force exerted by a spring and its length to determine the spring constant. You could also do this using simple harmonic motion. a. Describe an experiment you could do to find a spring constant using simple harmonic motion. What would you measure, and how would you average your measurements? b. Pretending you did the lab this way, make up reasonable measurements and compute the spring constant for those measurements.

In a lab involving a pulley, a block, and a spring scale to measure force, imagine the following scenario: You tie one end of a meter-long string to something fairly solid like a doorknob. You put the pulley over this string, so the sheave of the pulley is on top of the string, and the other end of the string goes straight back up. Then, the block is hung directly from the pulley. Q1: Predict, using Newton’s second law and...
