How Do You Calculate Frequency and Period for a Mass on a Spring?

AI Thread Summary
To calculate the frequency and period of a mass on a spring, the frequency (F) is determined by dividing the total number of vibrations by the total time, resulting in F = 25 vibrations / 50 seconds = 0.5 Hz. The period (T), which is the time for one complete vibration, is the reciprocal of frequency, so T = 1/F = 1/0.5 = 2 seconds. The user is confused about the formula for period involving the spring's length (L) and gravitational acceleration (g), which are necessary for further calculations. The key formulas are F = 1/T and T = 2π√(L/g). Understanding these concepts is essential for solving the problem accurately.

Waves and Sound Vibrations Question Urgent Please Help??

Homework Statement


A mass suspended from the end of a spring vibrates up and down 25 times in 50s. What ar ethe frequency and period of the vibration.


Homework Equations


F = 1/T
T = 2(pie)3.14(squrroot)L/g


The Attempt at a Solution


F = 1/T
or is it:
F = 50/25
F = 2Hz?

T = 2(3.14)(sqrroot) but what is the L?

I'm very confused and I need to finish this soon!:confused::frown::cry:

Frequency = number of vibrations per second.
Period T = time for one vibration = 1/f
 

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 .

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...
