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.

first of paragraph? and second of statment?

don't submit such stupid questions!

c hydrophobia is the answer

1. the relationship between a pronoun and its antecedent- reference

reference refers to the relationship between mainly pronoun and another unit of grammar- noun phrase or noun.

2. a singular noun naming a collection or group- collective noun.

collective noun refers to the kind of noun which refer to the name of people, thing or anything in collective. for instance bundle of sticks, herein 'bundle' is collective noun.  

3. a modifying clause whose subject and/or verb is implied- elliptical clause

it is a clause in which words are being left out. on the other hand, the missing word is understood due to the logic or pattern of the sentence.  

4. two or more nouns and/or pronouns serving the same grammatical function and followed by a pronoun that references one or all nouns- compound antecedent

compound antecedent refers to which is made up of two or more words which are joined by 'or' or 'and.'

5. an adjective clause introduced by a pronoun- relative clause.

relative clauses are the clauses which begin with the relative pronouns such as when, where, which, that or who. the noun that precedes, relative pronouns identify or define that noun.  

6. the word, phrase, or clause to which a pronoun refers- antecedent.

antecedents refers to the phrases, clauses or words which are replaced with one of the third personal pronouns.

the correct answer is: a) every day, the children play and swim in the lake.

explanation: the topic is about the children playing and swimming everyday in the lake, the rest of the sentence is only a positive description of the outcome of such events.
