3. (d) A system has output x and input y. Output varies with time and input y is given by 5 * (d ^ 2 * x)/(d * t ^ 2) + 20 * (dx)/(dt) + 12x = 13y (iii) Express the system output as a function of time. (ii) What is the damped angular frequency?

Fluids at rest possess no flow energy. a)- true b)- false

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.
