Find the pressuer exerted on the skin of a balloon with a force of 2.1 N usint (a) your finger of (b) a needle. Assume the area of your finger tip is 1.0xx10^-4m^2 , and the area of the needle tip is 2.5xx10^-7m^2 . (c ) Find the maximum force necessary to burst the balloon with the needle given that the balloon bursts with pressure of 3.0xx10^5(N)/(m^2) . What insight you gain from the results obtained?
