a) The diagrams shown below are the result of executing an algorithm that has one parameter, N, which must be a non-negative integer and alphabet boxes on a 10<10 grid. For values of N from O to 5, the algorithm produces the following patterns:

This question came in 2018 in my University's semester final. And I have no idea how to solve this or how to approach this 6 mark question. Please help me and thank you in advance.

Q=An amplifier uses a GaAs HBT device having the following scattering parameters (Zo = 50 Ω). S11 = 0.61< −170◦, S12 = 0.06< 70◦, S21 = 2.3< 80◦, and S22 = 0.72< −25◦. The input of the transistor is connected to a source with Vs = 2 V (peak) and ZS = 25 Ω, and the output of the transistor is connected to a load of ZL = 100 Ω. (a) What are the power gain, the available power gain, the transducer power gain, and the unilateral transducer power gain? (b) Compute the available power from the source, and the power delivered to the load.

1. Identify the potential (possible) market, establish customer needs, and then set
up design objectives, design constraints (limitation), and criteria (measure) for
design evaluation for the following devices:
a. Cellphone charger powered by kinetic energy
b. Automatic floor cleaner

dy/dx=2(3x+y)^2-1 when x=0,y=1

please use bernoulli's equation to solve
