Hey, for the first part price in the long run equilibrium will be minimum of average cost. So minimize 0.5q10+w/q wrt q. U get q=root(2w). Min AC comes out to be root(2w)10. This is the price. From here get quantity demanded in terms of w. Quantity supplied is 0.25w.root(2w). Equate them to get w. U can get the other variables from there. Now see if u can do the other parts.
