Laila and Majnu are on a boat for a picnic. The boat is initially at rest. Laila has a big watermelon which she throws towards Majnu. The man catches the melon and eats half of it. He throws back the remaining half to Laila. She eats the half of the melon that she receives & throws the remaining part to Majnu. Majnu again eats half of what he receives and returns the remaining part back to Laila. This continues till the melon lasts. The two are sitting at the two ends of the boat which has a length . Combined mass of the boat and the two lovers is and the mass of the water melon is M. Assume that the boat can move horizontally on water without any resistive force. Find the displacement of the boat when the watermelon gets finished.

The great importance of periodic sine and cosine functions is due to a resuit provexpressed as ? mathematician, Jean Baptiste Joseph Fouriers (Any periodic function can ite coefficients). Example 3: Which of the following functions of time represented (a) periodic and (b) non-periodic motion? Give the period for each case of peniodic motion ( is any positive constant) (i) (ii) . Solution: (i) is a periodic function. It can be written as \[ \begin{aligned} & \sqrt{2}\left(\sin \omega t \frac{1}{\sqrt{2}}-\cos \omega t \frac{1}{\sqrt{2}}\right) \\ = & \sqrt{2}\left(\sin \omega t \cos \frac{\pi}{4}-\cos \omega t \sin \frac{\pi}{4}\right) \\ = & \sqrt{2} \sin \left(\omega t-\frac{\pi}{4}\right) \\ = & \sqrt{2} \sin \left(\omega t-\frac{\pi}{4}+2 \pi\right) \\ = & \sqrt{2} \sin \left[\omega\left(t+\frac{2 \pi}{\omega}\right)-\frac{\pi}{4}\right] \end{aligned} \] The periodic time of the function is (ii) The function increases monotonically with time . It, therefore, never repeats its value and is a non-periodic function. As diverges to . It, therefore, cannot represent any type of physical displacement.

You want to assess the exposure to fine particles of the population near the edge of the city; this problem will walk through some of the steps necessary to approach this objective. One way to model the dispersion of pollutants around a city is to discretize (separate the territory into squares of 1 km on each side, and represent the air above up to 500 m above ground (precise dimensions). These boxes (control volumes) are then considered as CSTR. In Montreal, there are approximately A dwellings/km. You are interested in determining the effects (risk) on air quality if all dwellings had a wood fireplace, knowing that a wood fireplace emits B mg/sec of fine particles. These particles can settle out of the atmosphere at a first-order rate of C hour^(-1). Consider two adjacent 1 km regions: one at the edge of the city (i.e., clean air is flowing into it), and the other one immediately downwind from the first one. Consider also that the wind is horizontal and perpendicular to the face of the control volume, and at a speed of D m/sec.
  1. What do you expect to be the steady-state concentrations of fine particles (in mg/m^3) in each region?
  2. If you start without any fine particles in suspension, how long would it take to reach precisely 95% of the steady-state in the first region (give the time in min)? Since steady state is only reached at an infinite time, this time is when the system is considered to have reached steady state.
  3. Without additional calculations, do you expect the second region to reach steady state at the same time, before, or after the first region? In case of a time difference, is this difference significant compared to the initial concentration at t=0?
  4. Knowing that people heat only at night for approximately 12 hours, you decide to simplify your exposure calculations by assuming that the steady-state concentrations occurred for the entire 12 hours. Is this assumption justifiable based on the answer in (b and c), and based on your knowledge of a CSTR? Consider that this analysis already has a number of assumptions with various degrees of precision.
