Three objects, cylindrical rod (radius = 0.1 m), steel ball (radius = 0.1 m) and flat screen (length = 0.1 m) with surface temperature of 65 ℃ are exposed in perpendicular direction to water flow at 30 m/s and 30 ℃. Assume the area of all three objects are the same as 1 m2 , determine the individual values of convective heat transfer coefficient for each object, and their respective heat loss.

ASK YOUR TEACHER According to a survey conducted in a certain year by the Federal Communications Commission (FCC) of 3005 adults who were home broadband users, 31.5% of those surveyed had switched their service over the past 3 years. Of those who had switched service in the past 3 years, 53% were very satisfied, 37% were somewhat satisfied, and 10% were not satisfied with their service. Of the 68.5% who had not switched service in the past 3 years, 46%...

ASK YOUR TEACHER In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. In environmental studies, sex ratios are of great importance. Wolf society, packs, and ecology have been studied extensively at different locations in the...

My Notes Ask Your Teacher The U.S. Census Bureau reported that in 2015 the proportion of adult Americans, ages 25 and older, who have a bachelor's degree or higher is 0.325.† Consider the population of all adult Americans, ages 25 and over, in 2015 and define p̂ to be the proportion of people in a random sample from this population who have a bachelor's degree or higher. (a) Would p̂ based on a random sample of only 10 people from...

In main, create two FracList objects, ask the user how many elements to allocate for each list, read as many Fraction objects from the keyboard as specified by the user into each (using >> operator). Sort both lists using the sort member function and display them; and then search for a value read from the user in both lists and print the index of the first occurrence or that it could not be found in either list. Swap the two...

ASK YOUR TEACHER question Sociologists say that 80% of married women claim that their husband's mother is the biggest bone of contention in their marriages (sex and money are lower-rated areas of contention). Suppose that twelve married women are having coffee together one morning. Find the following probabilities. (For each answer, enter a number. Round your answers to three decimal places.) (a) All of them dislike their mother-in-law. (b) None of them dislike their mother-in-law. (c) At least ten of...
