- Hi! Can you help me now? I need to review today for our exam tomorrow, I hope you can help me ASAP. Round off the final answer to 3 decimal places.Answer must be in standard form scientific notation with SI units that do not have prefixes ( except for kg.) all angles and directions must be calculated to the nearest 0.1 deg. (Tenth of a degree) and entered in standard form scientific notation.Calculating lung volume in humans. In humans, oxygen and carbon dioxide are exchanged in the blood within many small sacs called alveoli in the lungs. Alveoli provide a large surface area for gas exchange. Recent careful measurements show that the total number of alveoli in a typical pair of lungs is about 480 x 10 6 and that the average volume of a single alveolus is 4.2 x 10 6 cubic micrometer.
- solve 2c using engineering notationProblem 13: In this problem, the symbols M, L, and T represent the dimensions mass, length, and time, respectively. Consider the physical quantities s, v, a, and t with dimensions [s] = L, [v] = LT-1, [a] = LT-2, and [t] = T. (Here, the square bracket means “the dimensions of” so, for example, [s] represents the dimensions of the quantity s.) Part (a) What is the simplest expression involving only a and s that has the same dimensions as v2? expression = ______ Part (b) What is the simplest expression involving only v and t that has the same dimensions as a? expression = ______ Part (c) What is the simplest expression involving only v and t that has the same dimensions as s? expression = ______ Part (d) What is the simplest expression involving only a and t that has the same dimensions as s? expression = ______calculate the following and express the answer in the proper number of significant figures: (3.245x0.035x9.0023)/(4.076x2.01x42.3)
