Only the best--physics(unit analysis) question 1. The problem statement, all variables and given/known data Ok, this is under the unit analysis section: -----------> We can express the radius of the fireball (resulting from a bomb) R in terms of t, ρ and E as R= const2x E^(1/x)t^(-y/x)ρ^(−z/x). Verify the relationship between R and t (That is R is proportional to t^(–y/x)) by plotting log (R) vs log (t) using the information provided in the pictures. Fit the data of log (R) vs log (t) with a straight line. What is the slope of the fit? What does the slope mean? Can you see why we are plotting log (R) vs log (t) instead of R vs t? --Basically, the pictures show the fireballs of a bomb with the diameter(m) at certain times(ms): 6ms--80m 120ms--110m 53ms--180m 2. Relevant equations - Is it me, or is the question too vague? I am trying to understand what it's asking and how I should answer. 3. The attempt at a solution In the previous question, I have found z= 1 y= -2 and x= 5 for the values in the R=.... equation. However, I don't know what they mean by plotting the log and fitting the data. I have tried graphing log (x) and log (x^(2/5)) but it doens't seem correct. Thank you in advance.
