2. The dimensions of length (L) are expressed into G*ch?, where G,c and h are the universal gravitational constant (G), speed of light (c) and plank's constant (h). Identify values of x,y and z. [Note: Take dimensional values of G = M-1L³T=2 ,c = L'T¯1 "י דוH '"זח ןידEj"

0 5 10 40 35 30 25 20 Answer: 5 10 40 35 30 25 20 Suppose that you measure the length of an object by using a mictometer caliper and read the measured length as shown in the figure. Write down the value you read from the figure in units of mm. Pay attention to use the correct number of significant figures.

Problem 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 = ______
