<h2>Answer:</h2>
786Ω and 20.32Ω respectively.
<h2>Explanation:</h2>(a) Given a number of resistors each with its own resistance, the largest resistance can be obtained when these resistors are connected in series.
From the question, the resistors have the following resistances;
36.0-Ω, 50.0-Ω , and 700-Ω
Now, when they are connected in series, the total resistance (R) obtainable is given by the sum of these individual resistances as follows;
R = 36.0-Ω + 50.0-Ω + 700-Ω
R = 786Ω
Therefore, the largest resistance that can be obtained by connecting a 36.0-Ω , a 50.0-Ω , and a 700-Ω resistor together is 786Ω
(b) Similarly, given a number of resistors each with its own resistance, the smallest resistance can be obtained when these resistors are connected in parallel.
From the question, the resistors have the following resistances;
36.0-Ω, 50.0-Ω , and 700-Ω
Now, when they are connected in parallel, the total resistance (R) obtainable is given by using the relation as follows;

R = 20.32Ω
Therefore, the smallest resistance that can be obtained by connecting a 36.0-Ω , a 50.0-Ω , and a 700-Ω resistor together is 20.32Ω
It can be noted that the directions west and north are perpendicular to each other. hence we can use the right angle formula for calculating total distance in these directions. Also South is just negative north. This technique is called euclidean distance norm. It is the basis of Cartesian coordinate system.
Total distance = 3.22 N + 4.75 W +1.90 S
= 1.32 N + 4.75 W
D =
D = 4.93 Km
direction = atan(N/W) = 15.53 deg north of west
