Additional information:
The 10% cumulative, convertible preference shares were issued at the beginning of 2017. Each preference share is convertible into two ordinary shares. On 1 July 2018, 50,000 convertible preference shares were converted into ordinary shares.
Both convertible bonds were issued in 2017. Each bond has a face value of RM1,000 and is convertible into 25 shares of ordinary shares. In 2018, interest expense for convertible bonds (Issue A) is RM200,000 and interest expense for convertible bonds (Issue B) is RM90,000.
Shares options were granted at the beginning of 2017 to purchase 200,000 ordinary shares at RM20 per share. During 2018, the average market price of the shares was RM25 per share.
The board of directors authorized a 3-for-1 share split which became effective on 1 September 2018. The rate of conversion for convertible securities and the right under shares options are adjusted for the share split.
Income tax rate is 26%.
Preference dividends were not declared in 2018.
Net income in 2018 was RM7,500,000.

2. Using the Henderson-Hasselbalch equation, calculate the concentration ratio ([sodium acetate]/[acetic acid], the amount (number of mole)of acetic acid and sodium acetate, and the volume of 0.1 M acetic acid and 0.1M sodium acetate solutions needed to prepare 110 mL each of the following buffer solutions with concentration of 0.1M: a. Buffer 4, pH 3.76 Same approach as Buffer 1. Refer to the summary table for the preparation of buffers (Table 4). b. Buffer 5, pH 4.76 Same approach as Buffer 1. Refer to the summary table for the preparation of buffers (Table 4). c. Buffer 6, pH 5.76 Same approach as Buffer 1. Refer to the summary table for the preparation of buffers (Table 4).
A hydro-electric station has an average available head of 100 meters and reservoir capacity of 50 million cubic meters. Calculate the total energy in kWh that can be generated, assuming hydraulic efficiency of 85 % and electrical efficiency of 90%.
A reaction mixture was spotted on a TLC plate and the plate was developed. The starting material had one spot at Rf 0.65 (sample Y) and the reaction mixture had a spot at Rf 0.45 (sample X) ----- XY no reaction had occurred. one product with Rf 0.45 was formed one or more products were present, and all have Rf = 0.45 one product was formed but there was still starting material.

Y15) Fig. 4, Closed-loop system with parameters K and p Problem 8 Arc welding is one of the most important areas of application for industrial robots. In most manufacturing welding situations, uncertainties in dimensions of the part, geometry of the joint, and the welding process itself require the use of sensors for maintaining weld quality. Several systems use a vision system to measure the geometry of the puddle of melted metal, as shown in Fig. 5. This system uses a constant rate of feeding the wire to be melted. Calculate the maximum value for K for the system that will result in a stable system.

The goal of vertical takeoff and landing (VTOL) aircraft is to achieve operation from relatively small airports and yet operate as a normal aircraft in level flight. An aircraft taking off in a form similar to a missile (on end) is inherently unstable. A control system using adjustable jets can control the vehicle, as shown in Figure 2. (a) Determine the range of gain for which the system is stable. (b) Determine the gain K for which the system is marginally stable and the roots of the characteristic equation for this value of K.

A 100 mm by 50 mm Venturi meter is installed in a 100 mm diameter pipe to measure the flow of a certain liquid (sp gr 1.20). A differential gage connected with the inlet and throat contains a substance (sp gr 1.5) in the lower part of the tube, the remainder of the tube being filled with the certain liquid. The difference in height of water columns in the two legs of the tube is 75 cm. If the coefficient of the meter is 0.97, compute the actual discharge. A Venturi meter 45 cm by 20 cm has its axis inclined upwards 300 from the horizontal. The distance measured along the axis, from the inlet to the throat is 1.20m. The differential manometer shows a deflection of 25 cm of mercury. If the flowing fluid has specific gravity of 2.0, find the discharge if C = 0.96. A 50 mm venturi meter (C = 0.98) is installed in a 75 mm diameter horizontal pipe carrying oil having specific gravity of 0.83. If the recorded flow in the meter was 25 liters per second, what could have been the deflection of water in the differential manometer connected between the inlet and the throat?
