Which of the following is a disadvantage of using face-to-face communication over other communication channels? A) There is lag time between transmission and reception of the message. B) It is often difficult to schedule a time to meet face-to-face. C) Face-to-face communication reduces your ability to hold the receiver's attention. D) It is more difficult to develop effective relationships with individuals when you use face-to-face communication.

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x, y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
