11.10 A large amount of energy E is suddenly released in the air as in a point of explosion. Experimental evidence suggests that the radius r of the high-pressure blast wave depends on the t as well as the energy E and ⍴ the density of the ambient air. Using the Buckingham method, find the equation for r as a function of, t, ⍴, E. Show that the speed of the wave front decreases as r increases.
