AI Thread Summary
To solve the homework question on wave period, frequency, and velocity, it's essential to understand the definitions and units of these terms. The period is the time it takes for one complete wave cycle, measured in seconds. Frequency is the number of waves that pass a point in one second, expressed in hertz (Hz), while velocity refers to the speed of the waves, typically measured in meters per second (m/s). Given that two waves arrive every five seconds, the period is 5 seconds, the frequency is 0.4 Hz, and the velocity can be calculated using the wave separation distance. Understanding these concepts is crucial for accurately answering the questions posed.

Here is the Question.

You observe water waves coming to shoreon a large lake. You obseve that every five seconds, two more waves come in, and that the waves are seperatedby four meters.

a) What is the period of the waves?
b) What is the frequency of the waves?
c) What is the velocity of the waves?

Where do I start?

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}...
