- Each of the following equations was given by a studentduring an examination: (a) 1/2 mv2= 1/2 mvo2 + √mgh (b) v= v0 +at2 (c) ma =v2 Do a dimensional analysis of each equationand explain why the equation can’t be correct.If you make multiple measurements of your height, you are likely to find that the results vary by nearly half an inch in either direction due to measurement error and actual variations in height. You are slightly shorter in the evening, after gravity has compressed and reshaped your spine over the course of a day. One measurement of a man's height is 6 feet and 1 inch. Express his height in meters, using the appropriate number of significant figures.A person running through the forest with equation: y(x, t) = (1.1 m)cos(3.1x – 7.1t) for which x has units of meters and t has units of seconds.

- Consider the table where the primary dimensions of several variables are listed in the mass– length–time system. Some engineers prefer the force–length– time system (force replaces mass as one of the primary dimensions). Write the primary dimensions of three of these (density, surface tension, and viscosity) in the force– length–time systemd²y Let 4 - 5y = 0, suppose the solution has the form y = e1x. - dx2 dx Find the Characteristic Equation of å and find the roots of the equation.Suppose your hair grows at the rate of 1/34 inch per day.
