For the functions below:

i)G (W,X,Y,Z) = Σm (1, 4, 7, 8, 9, 11) + d (0, 3, 5)

ii)F (A, B, C, D) = Σm (7, 9, 12, 13, 14, 15) + d (4, 11)

iii)F (A, B, C, D) = πM (2, 8, 11, 15) + d (3, 12, 14)

iv)F (W, X, Y, Z) = πM (0, 2, 6, 11, 13, 15) + d (1, 9, 10, 14)

a)Identify the essential prime implicants

A projectile launcher is used to launch a 0.5 kg ball into the air. The

launcher is connected to a 1-kg mass and starts from rest with the spring compressed to a

length of 15 cm. The unstretched length of the spring is 75 cm. When the launcher is

released from rest, the 1-kg mass will impact the ball and the ball will project in the air.

Determine a suitable spring constant and angle θ for the ball to reach a maximum height of

20 m (measure from the current position of the ball). The Coefficient of restitution between

1-kg mass and ball is 0.8. (Note: first determine an arbitrary angle and find the spring

constant for that)

Simulation 1 Aim: Determine the true power dissipated in the load of a single-phase half-wave rectifier fed from a 220 V 50 Hz supply. The load resistor is equal to the last two numbers of your student number + 10 ohm. [25] 

Calculate the mass moment of inertia for the thin parabolic plate about the x-x axis as shown in the figure below.

In slurry reactor pure reactant gas is bubbled through liquid containing suspended catalyst particles. Initially the reactant gas which enters the liquid must diffuse through the liquid film surrounding the catalyst particle. At the surface of particle reactant yields product according to first order kinetics .Draw the concentration profile of gaseous reactant in slurry reactor and derive an expression for the rate of reaction in terms of resistances encountered in the reactor.

find response (deflection) y (x,t) of The Vibrating string Length (L=𝜋), end fixed

c²=1 if The initial displacement and Initial Velocity are:

y (x,0) = o , 𝑦'(x,0) =0.1 Sin2x.

y (x,0) = o , 𝑦'(x,0) =0.01x , if 0 ≤ 𝑥 ≤𝜋/2

𝑦'(x,0) =0.01(𝜋 -x) , if 𝜋/2≤ 𝑥 ≤ 𝜋

y (x,0) = 0.1 Sinx , 𝑦'(x,0) = - 0.25 Sinx.
