how about the rest of the problem? still lost

well in that case for a you would just hang the mass from the spring, measuring the length of x before and after hanging the mass, calculate F (Mg) then divide F by x to get k. But I thought you would need at least a trial to get an accurate one?

In the laboratory, you are given a cylindrical beaker containing a fluid and you are asked to determine the density ρ of the fluid. You are to use a spring of negligible mass and unknown spring constant k attached to a stand. An irregularly shaped object of known mass m and density D(D>>ρ)...

To demonstrate standing waves, one end of a string is attached to a tuning fork with a frequency of 120 Hz. The other end of the string passes over a pulley and is connected to a suspended mass M. The value of M is such that the standing wave pattern has four "loops". The length of the string...

but i am having a little trouble figuring out how i can determine the weight using torque. Does anyone have any ideas?

"now used in a spring scale that is limited to a maximum value of 25N, but you would like to weigh an object of mass M that weighs more than 25N. You must use commonly available equipment and the spring scale to determine the weight" one spring scale but I think the torque thing is fine, thanks

A spring that can be assumed ideal hangs (vertically) from a stand. a. You wish to determine the spring constant k of the spring. i. What additional equipment do you need? ii. What measurements would you make? iii. How would k be determined from these measurements? b...

A block of mass M is resting on a horizontal, frictionless table and is attached to a relaxed spring of spring constant k. A second block of mass 2M and initial speed vo collides with and sticks to the first block. Develop expressions for the following quantities in terms of M, k, and Vo. a)...

Two 10 kilogram boxes are connected by a massless string that passes over a massless frictionless pulley as shown above. The boxes remain at rest, with the one on the right hanging vertically and the one on the left 2.0 meters from the bottom of an inclined plane that makes an angle of 60° with...

1. Which rolls to the bottom of a hill sooner, a car tire alone or the same tire mounted on a rim? a. The mounted tire, provided the tire is more massive than the rim b. The tire alone, provided it is as heavy as the rim c. The mounted tire, provided the tire is as heavy as the rim d. The...

In the figure below, the pulley is a solid disk of mass M and radius R, with rotational inertia (MR2)/2. Two blocks, one of mass m1, and one of mass m2, hang from either side of the pulley by a light cord. Initially, the system is at rest, with Block 1 on the floor and Block 2 held at height h...
