What Happens to a Loudspeaker When the DC Power is Cut Off?

AI Thread Summary
When DC power is cut off from a loudspeaker, the speaker coil, which is held in an equilibrium position, will begin to return to that position. Initially, the sudden loss of power can cause the speaker cone to move due to inertia, resulting in a brief vibration or oscillation. This movement occurs as the coil reacts to the abrupt change in magnetic field. Eventually, the speaker will come to rest in its equilibrium position. Understanding these dynamics is crucial for analyzing loudspeaker behavior during power interruptions.

When a loudspeaker is connect to a direct current the force is in the same direction right, and no vibration will occur... But what would happen if the batter was quickly switched off? I can't seem to work this question out... PLEASE help!

The speaker has an equlibrium position maintained by the mounting of the speaker coil. When the DC is switched off, it will return to that position, eventually. What do you think is likely to happen before it finally comes to rest?
 

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}...
