AI Thread Summary
To determine the force constant of a rubber band using a 100g mass, a stopwatch, and a meter stick, two methods can be applied. The first method involves measuring the period of oscillation using T = 2π√(m/k), where k represents the force constant. The second method utilizes Hooke's Law, F = -kx, by applying a known force and measuring the resulting extension of the rubber band. Clarification is provided that the 'force constant' indeed refers to the 'spring constant.' These methods effectively allow for the calculation of the rubber band's force constant.

Describe two different ways to determine the force constant of a rubber band only a 100g mass, a stopwatch, and a meter stick.

I don't really understand what its asking but I don't have many formulas to choose from so I don't really know where to begin. I have like f = 1/T y = A * cos (2pi/T * delta T) etc... T = 2pi * sqrt(m/k) and F = -kx. Is it referring to the force constant or SPRING constant? Can someone give me a hint? It should be very easy but I'm having a really hard time here :cry:

I think that the 'force constant' is referring to the 'spring constant'. If this is the case you can use two of your formula's above.
 
T = 2pi * sqrt(m/k) and F = -kx? ok thanks!

They're the one's :smile:
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
