How do periods and masses relate in oscillating springs?

AI Thread Summary
The discussion focuses on the relationship between the period of oscillation and mass in a spring-mass system. Participants emphasize the need for the correct equation that connects the period to the spring constant and mass, rather than using the phase constant equation. There is a debate on how adding mass affects oscillation speed, with some suggesting it slows down oscillations while others argue it reduces time. The correct approach involves deriving or identifying the appropriate formula linking these variables. Understanding this relationship is crucial for solving the problem effectively.

Welcome to the PF.

The Relevant Equation that you list is not applicable. Look for an equation that relates the period of oscillation of a spring+mass system to the spring constant K and the mass m. (or else just derive the equation yourself from what you know about how springs and masses work...) :-)
 
Now that I look at it closely. The answer has got to be C because each oscillation is the same as the previous.

I don't think so. Adding mass will slow down the oscillations...
 
I see so the answer has got to be E since we know its the same cylinder it would reduce the time by twice.

No. You need the equation which relates period and mass.

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}...

Thread 'Struggle to understand the concept of the 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...
