(b) A piece of stretched rubber exerts a force of 5 N. How much work (in J) has to be done on the rubber to stretch it one centimeter?

5.ine burns a stoichiometric mixture of fuel (liquid hydrogen) in oxidant (liq The combustion chamber is cylindrical, 1.2 m long and 80 cm in diameter, and the combustion process produces 306 kg s' of exhaust gases. 2H2(I) + O2(I) = 2H2O(g). The reactor volume and me in which reaction takes place are identical. If combustion is complete, value of the rate of reaction of oxygen in kgmol m3 sl? Note:
