AI Thread Summary
To calculate the speed of a longitudinal wave with a frequency of 20 Hz and a wavelength of 0.4 m, the formula used is v = wavelength times frequency. Substituting the values, the calculation is v = 0.4 m * 20 Hz, resulting in a speed of 8 m/s. The calculation appears to be correct based on the provided parameters. This method is a standard approach for determining wave speed in physics. The discussion confirms the accuracy of the calculation.

1. A periodic longitudinal wave that has a frequency of 20.0 Hz travels along a coil spring. if the distance between successive compressions is 0.4m, what is the speed of the wave?


2. v= wavelength times frequency



3. v= wavelength times frequency
= 0.4 * (20)
= 8 m/s ------ I'm not sure if this is right.

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}...
