A pizza parlour will deliver a pizza take-away order to the customer if s/he lives within a 5 kilometre radius from the pizza parlour. If the customer lives within this radius, it is found that the time taken to receive the pizza is normally distributed with a mean time of 45 minutes and a standard deviation of 8 minutes. If the time to receiving the pizza exceeds a particular time period, the customer gets the pizza free of charge. What should the approximate time limit (to the nearest minute) until delivery for the pizza be if the pizza parlour wants no more than 10% of the customers to get a free pizza?
A string is 7.63 m long with a mass of 8.56 g. The string is held taut with a tension of 457 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?

Application limitations and strength of Mossbauer spectroscopy
Working principle of Mossbauer spectroscopy
A wave is modeled with the function y(x,t) = (0.8m) cos((1rad/m)x − (0.62rad/s)t + π/3). Find the wave speed.
An insulated cup contains 330 g of water at 20 °C. A 100 g sample of an unknown material at 76 °C is added. The final temperature of the water and metal is 47 °C.
Specific heat capacity of water = 4160 J/kg-°C
What is the specific heat capacity of the unknown material {_1} J/kg-°C
A body of mass 4 kg, projected at an angle of 65° from the ground with an initial velocity of 36 m/s, acceleration due to gravity is g = 9.81 m/s2, determine:
a) time of flight
b) maximum horizontal distance covered
c) maximum vertical distance covered
In a machine, an effort of 50 N lifted a load of 350 N. If effort lost due to friction at this load is 12.5 N. Find
a) Ideal Effort
b) Mechanical Advantage
c) Velocity Ratio
Use a single-subscripted array to solve the following problem. A company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9 percent of their gross sales for that week. For example, a salesperson who grosses $3000 in sales in a week receives $200 plus 9 percent of $3000, or a total of $470. Write a C program (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assume that each salesperson’s salary is truncated to an integer amount):
a) $200–299
b) $300–399
c) $400–499
d) $500–599
e) $600–699
f) $700–799
g) $800–899
h) $900–999
i) $1000 and over
