Name: Problem 2. (Option # 1 ) Five half wavelength dipole antennas are used as sources to form a linear phased array antenna, as shown below. These elements are all excited by sinusoidal current source of equal amplitude and phase followed by phase shifters. (9 pts.) a) If d 2, write the expression for array factor of the linear array. (9 pts.) b) Find total field at observation point P: (r, 0, 6) at far-field (i.e., kr>1). (8 pts.) c)...

Problem 2. (20 pts) As shown in the figure, uniform generation occurs inside the spherical core with a radius n due to reactive heating at a rate of q 10 W/m3. The thermal conductivity of the reactive material is 20 Wm. K. The spherical shell 1Sr is made of stainless steel (s.s.) with a thermal conductivity k2 -15 W/m K. Given 0.5 m and k2 72=0.6 m, water flows outside to cool the s.s. shell at To-25°C and h =...
Given: A(amplitude)=6.13 cm; x(0)= -5.4 cm; T(period) = 1.7s; a(0)=73.8 cm/s^2; v(0)= 10.7 cm/s I need a solution to the following problem: As you can see I already requested the answer so I don't know how to solve it. Also what do they mean by 'phase'? i thought the phase constant is constant so this is confusing. Part D What is the phase,expressed in degrees, at each of three different times: the first time is one-third of a period, t...
Java maze problem: Given a maze represented by a 2-dimensional array with 0’s (wall) and 1’s (open path), the goal is to find the path from a given initial location (rowIni, colIni) to a final location (rown, coln) using recursive backtracking. A move can be made to a location only if there is 1 in the neighboring coordinate. A position that is part of path should be marked with the character +. When a path from initial location to final...
A 3-phase, 1000-MVA, \(20-\mathrm{kV}, 60-\mathrm{Hz}\) synchronous generator is connected to an infinite bus as shown below. All impedances are given in pu values. The generator delivers \(0.9\) pu power at unity power factor to the infinite bus whose voltage is at 1 pu.If phase 'A' of circuit 2 (CCT 2) between buses H1 and H2 is suddenly opened at point ' \(\mathrm{F}\) ' near bus H1 due to the opening of a circuit breaker, determine:(a) [10 marks] The internal voltage...
