Solving Sine Waves Problem: Find Time for π Radians

Sine Sine waves Waves

AI Thread Summary

The discussion centers on calculating the time it takes for a sine wave with a frequency of 10Hz and an amplitude of 5 units to reach a phase of π radians. The equation used is y(t) = A . sin(2.π.f.t + φ). A user initially calculated the time as 0.038 seconds, but expected the answer to be 0.005 seconds. The discrepancy in the results suggests a potential error in the phase calculation or the application of the sine function. Clarification on the correct approach is sought to resolve the confusion.

A sine wave with a frequency of 10Hz and an amplitude of 5 units phases from zero to 2π radians in a complete cycle. How long does it take for the phase to reach a value of π radians?

y(t) = A . sin (2.π.f.t + φ)

0.1 = 5 x sin (2x∏x10x time + 3.14)

time = 0.038 seconds

But the answer suppose to be 0.005 and I got 0.038.

Thank you!

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...
