A) In an experiment to determine the unknown impedance of a microwave antenna, a slotted section of transmission line is first connected to a short-circuit load. In this case, adjacent voltage minima are found 23.6 and 35.4 cm away from the load. Afterreplacing the short circuit with the antenna, the location of minima shifted to points 27.8 and 39.6 cm, respectively, away from the load with the VSWR value equal to 2.6. Assuming that the slotted transmission line is lossless of characteristic impedance Z 0 = 50 0 and the velocity of propagation u =c, determine the following: i) Operating frequency ii) Unknown impedance of microwave antenna. B) It is required to match the antenna in part a to a section of transmission line of characteristic impedance Z. = 50 12. C) It is suggested that we insert a length d of a 50 12 lossless transmission line between the antenna and the side A-A of the double stub tuner. Find the minimum length of such a transmission-line section and the lengths d, and d2 of the stubs required to achieve matching.

halloween: it’s my favorite holiday

halloween is one of the best holidays for some people but it can also be scary for others. halloween is a holiday where some people believe spirits and soul of the dead that haven’t moved on will come back again to haunt the lives of the living. this is why many people dress up in costumes to disguise themselves as someone else. some people like us wish to be something that we would benefit in life from. like angels of god. some dress up just to be unique from the others. many families stay home and watch scary movies and others dress in their tremendous costumes and knock on each door to either get a trick or a treat.

personally everybody loves halloween because i could be someone else one day out of the year. it’s fun and entertaining, especially for kids. halloween also has a lot of history. many myths and beliefs say that witches and warlocks are alive and living among us. is this a trick or a truthful treat?

halloween may have secrets and scary things behind the door but we love halloween and it is beautiful to see how happy children are when each door opens full of treats and goodies. it makes everyone happy. happy halloween day.

happy to .

pls mark as brainliest.

the answer is most likely c. it shows us that the rules that the pigs make can change on a whim whenever it suits the pigs purpose.

hope this

an interrogative sentence is a type of sentence that asks a question, as opposed to sentences that make a statement, deliver a command, or express an exclamation. interrogative sentences are typically marked by inversion of the subject and predicate; that is, the first verb in a verb phrase appears before the hope i
