1) Calculate f and its uncertainty. Watch the units, and be sure to show all your work. Do not use sum of percentage method for the uncertainty. Use the Derivative method.

a) Calculate x*y

x=44.65±0.05cm

y= 27.35±0.05cm

b) Calculate d/t

d=64.25±0.05cm

t=21±2s

c) Calculate (x-y)/t

x=24.65±0.05cm

y=30.25±0.05cm

t=40±4s

d) Calculate m/(pi*r^2*h)

m=321.15±0.05g

r=2.15±0.05cm

h=8.15±0.05cm

Write a C++ program to demonstrate thread synchronization. Your main function should first create a file called synch.txt. Then it will create two separate threads, Thread-A and Thread-B. Both threads will open synch.txt and write to it. Thread-A will write the numbers 1 - 26 twenty times in nested for loops then exit. In other words, print 1 - 26 over and over again on separate lines for at least 20 times. Thread-B will write the letters A - Z...

​​​​​​ Below are ten functions. Find the first derivative of each. All of the derivatives can be found by using combinations of the constant rule, power function rule and sum-difference rule.   Do not use the product rule. It is not needed. The degree of difficulty (more or less) increases from (a) to (j). Be sure to show intermediate work. Five points are awarded for correctly developed derivatives. There is no partial credit, because an incorrect derivative is useless. For example,...
