Question 5 (8 marks) The cart in Figure 1 moves at constant velocity V, and takes...
A semi-infinite body of liquid, with constant density and viscosity, is bounded below by a horizontal surface. Initially, the fluid and solid are at rest. Then at time t = 0, the solid surface is set in motion in the positive x direction with a constant velocity vo = 10 m/s, as shown in Figure 4-1. y y = 5 cm t< 0 y = 0 cm Fluid at rest у y = 5 cm t = 0 y =...

QUESTION 2: (20 MARKS) +5 V X2 71 QA X2 ×10 5 V Figure Q2.1 The circuit shown in Figure Q2.1, is a multistage amplifier with a differential input stage It uses a folded cascode involving transistor Q3. Note that transistor Q5 operates in class B mode and is off at the quiescent point, while Q4 is ON at the quiescent point with QD sinking its bias current. All transistors have Vad-0.7V, VA-200 V, and β-100 a) Perform a dc...
GROUP ASSIGNMENT QUESTION- DUEDATE IS ON 29 MAY 2019 (5 P.M.) A research group from FKM, UTeM developed a Rain Harvesting System as shown in Figure 1 to minimize the flood in Sekolah Menengah Kebangsaan Iskandar Syah (SMKIS) with the help from teachers and students from the school. The heavy rain especially during the Northeast and Southeast Monsoon resulted in overflow of the existing drainage system in the school and causes soil erosion as shown in Figure 2. Instead of...
