"Detail the solution to the question with an explanation of the integration." The normalized radiation intensity is given by: 1 0≤0≤30 U(0,) cos(0) 30 ≤0≤90 0.866 0 90 ≤0≤180 Determine the maximum directivity, HPBW

2. Define two variables: alpha = 5a/8, and beta = /8. Using these variables, show that the following trigonometric identity is correct by calculating the values of the left and right sides of the equation. sina cosß = [ sin(a – B) + sin(a + B)] %3D

What is the phase angle between two 60-hertz voltages generations separated by a time interval of three milliseconds? Carry the answer to one decimal place. Hint: Theta = 360 *t *f

A workshop is 12m by 6 m by 4 m high and has workbenches 1 m high. Discharge lamps, each with an output of 3700 lm, are to be fitted in aluminium industrial reflectors at ceiling level. The surfaces have reflectances of 0.7 for the ceiling and 0.5 for the walls. The light loss factor is 0.7. The illuminance required on the workbenches is 400 lx. (a) Find the Utilisation Factor for the room. (b) Calculate the number of lamps required.

When the time basis signal is set to div/1usec, find the time required to scan the screen.
