Dimensional Analysis Practice Problems With Answers Exercises Problem 1.7.1.11 1.7.1. 11. make the conversion indicated in each of the following: (a) the men's world record long jump, 29 ft 4.5 in, to meters. (b) the greatest depth of the ocean, about 6.5 mi, to kilometers. (c) the area of an 8.5 by 11 inch sheet of paper in cm 2. There are two types of quantities used in dimensional analysis: an intrinsic quantity (e.g., 5 kilometers) a relationship, either given or known (e.g., 24 hours per day, 10 pens per box) proportions. relationships can be turned into proportions, because: 24 hours = 1 day. **divide both sides by 1 day**.
Dimensional Analysis Practice Worksheet With Answers Pdf вђ Askworksheet Answer. question 2. the velocity v of a particle depends upon the time ‘t’ according to the equation. determine the units of a, b, c and d. what physical quantities they represent. all have si units. answer. question 3. mass of the sun is 2.0 ×1030 2.0 × 10 30 kg and radius of sun is 7.0×108 7.0 × 10 8 m. Dimensional analysis exercise solutions 1. nondimensionalize the differential equation: d2x dt2 = −gr2 (x r)2, x(0) = 0, dx dt (0) = v 0 in this example, [x] = l, g is the acceleration due to gravity, r is the radius of the earth, and v 0 is initial velocity. note that this is the same one as in the text try to do it without referring back. 5. state true or false: dimensional analysis helps to know if the physical quantity is a vector or a scalar quantity. true. false. answer: b) false. explanation: dimensional analysis offers no information on whether a physical quantity is a scalar or vector. 6. match with the same dimensional formula quantity. force a) latent heat. The appropriate unit or value for d, e, f and g in the given dimensional analysis problems are as follows: d = 1 grame = 1000 milligramsf = 1 gramg = 0.25 kilogram. to solve dimensional analysis problems, we use conversion factors that relate two different units of measurement. here, we need to convert feet to miles in the first problem.
