Question 18. [-12 Points] DETAILS SERCP11 22.7.P.044. MY NOTES ASK YOUR TEACHER A boy floating on a pond watches a fish swim away from him as in the figure below. If the fish is 2.35 m beneath the surface, for what maximum distance d in m) will he be able to see the fish? Neglect the height of the boy's eyes above the water. HINT 2.35 m m Need Help? Read It

2.An object is pushed from rest across a sheet of ice, accelerating at 5.0 m/s2 over a distance of 80.0 cm. The object then slides with a constant speed for 4.0 s until it reaches a rough section which causes it to stop in 2.5 s. *(a) What is the speed of the object when it reaches the rough section? [3 marks] – . (b) At what rate does the object slow down once it reaches the rough section? [2 marks] – .(c) What total distance does the object slide throughout its entire trip? [2 marks]

The circuit below shows a filter commonly used as the output stage of a power supply. In this application, Vin(t) is switched between 0 and a DC input supply voltage (12V in this case). The filter smooths the switched input so that it is close some desired output from 0-12V. In this exercise, you are interested in determining the start-up behaviour of the system. To this end, do the following: a) Find the transfer function Your C). You may assume that the capacitor and inductor are initially de- Vin) energised. b) Att = 0, Vin(t) is switched to 12 V (i.e. Vin(t) = 12u(t) ). Find the time response Vout(t) = [-!{Vout($)}. Please use partial fraction expansion and the Laplace Transform table to conduct the inversion(s), showing all of your work and explaining your logic clearly to receive full credit. c) How long will it take for Vout(t) to reach 6V? You may use computer tools here, but please clearly explain your logic for full credit. d) Sketch (by hand) the Bode plot for G(s) with the parameter values from part b. As a part of this, please carefully compute and label: i. All asymptotes (e.g. low-frequency & high frequency) ii. All corner frequencies ii. The frequency and magnitude (in dB) of any resonances (if they exist) 50 x 10-3H 000 0.252 Vin(t) 0.2F 11 Vout(t) Figure 2: System for Question 3

the worst case. 4: Show that there are at most [n/2h+1] nodes of height h in an n-element heap

Receivables amount to P150,000. Receivable turnover is \( 10 \mathrm{x} \) and inventory is maintained at a level equal to 15 days' sales. Selling price per unit is P100 and has gross profit ratio of \( 40 \% \). A proposal has been made to change the term credit to \( \mathrm{n} / 60 \) to result to an increase in sales volume by one-third or by 5,000 units. Under this proposal, bad debts losses are estimated at \( 1 \% \) to \( 3 \% \) of sales but inventory turnover shall remain the same. How much is the increased accounts receivable? How much is the increased inventory? Compute for the increased operating income.

thank you😃, this will also help me in understanding the concept on this topic😃 2. Express the following absolute voltage gain to decibel power gain assuming that the resistance level are the same at the input and output. a. Av 2 b. Av = 21 C. Av = 0.2 d. Av = 10 =
