Dimensional Analysis: When multiplying several quantities
a. the quantities can have any combination of units.
b. the quantities must all have exactly the same units.
c. the quantities must all be dimensionless.
Homework Answers
Ans) the quantities can have any combination of units.
for example if we want to calculate the force, we have to multiple mass and acceleration with units kilogram and meter per second square. in the case of addition both should have same units

Dimensional Analysis: Often, we can almost derive formulas (up to an overall constant) just by knowing the units of the relevant quantities. Under the assumption that the pendulum's period can only depend on the pendulum's length L, m, maximum angle 0, and the strength of gravity g (with units [g]=m/s2), explain why we must have a relation like mass L T f(0) (Note that 0 counts as a unitless parameter here.) Asserting f(0)~ f(0) in this formula is the small...

While dimensional analysis is incredibly attractive, if you leave out even one important parameter or variable, you can have serious errors in your design and analysis. t turns out that you can develop similarity laws starting from the governing equations of a fluid motion. I challenge you to do that here. Show all of your work and your thinking 1) For a two-dimensional incompressible Newtonian fluid, non-dimensionalize the conservation of mass and conservation of momentum equations (shown below) ax in...

In this unit, we learned about measurements and dimensional analysis, which is referred to as conversion factors. Answer the questions below. Note: each question may have more than one part, so be sure thoroughly answer each part. You must provide a logical explanation with sufficient detail to demonstrate mastery of the chemistry concept related to the question in order to pass. Although there is not a length requirement, answers less than 250 words will likely not offer sufficient detail to...

Consider two countries, A and B. Each country produces only two goods with 1,000 production units: Wine and Cheese. Country A can produce 400 bottles of wine or 200 pounds of cheese or any combination of two goods. At the same time, country B can produce 1200 bottles of wine or 300 pounds of cheese or any combination of two goods. Suppose that both countries maximize their utility when they consume wine and cheese in equal proportions. 1. a) Absolute...

Purpose: The purpose of this lab is for you to design and implement several classes that use Inheritance. The problem: The program must handle a collection of different 2-dimensional shapes: triangles, rectangles and circles. All shapes have a color (use a Stringl and are either filled or not (use a boolean). All shapes must calculate and return their perimeter, and area. toStrina) for all shapes must implement the standardized formatting for inheritance. You are required to implement each of the...

The only quantities of good 1 that Barbara can buy are 1 unit or zero units. For x1 equal to zero or 1 and for all positive values of x2, suppose that Barbara's preferences were represented by the utility function (x1+12)(x2+8), and the price of x2is normalized to be 1. Then if her income were $36, what is the highest price would she pay for x1? (a) $3.38. (b) $6.77. (c) $1.50. (d) $4.50. (e) $0.57
