AI Thread Summary
To calculate the frequency of a pendulum that swings for 41.35 seconds over 20 cycles, first determine the period by dividing the total time by the number of cycles, resulting in a period of 2.0675 seconds per cycle. Using the relationship between frequency and period, where frequency (f) is the reciprocal of the period (T), calculate the frequency as f = 1/T. This gives a frequency of approximately 0.483 Hz. Understanding these relationships allows for accurate calculations of pendulum motion.

Homework Statement


Ok so I am given that a pendulum swings 41.35 seconds in 20 cycles. I have to find the frequency of that pendulum


Homework Equations


i know that f=1/T where T is period b/c frequency and period are reciprocal to each other.
i also know that f = N/t where t is the time for i think 1 cycle? but i don't know N


The Attempt at a Solution


Im not given Period so i have no idea how to solve for this. Please help! and please be specific on how u got your answer. Thx

Period is the time for ONE cycle.
You are given the time for 20 cycles.
Can you find the time for one?

You know the relationship between period and frequency.
 

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 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
