Consider an oblique shock wave with a wave angle of 36.87◦. the upstream flow is given by m1 = 3 and p1 = 1 atm. calculate the total pressure behind the shock using a. p0,2/p0,1 from appendix b (the correct way) b. p0,2/p1 from appendix b (the incorrect way) compare the results.

neither accurate nor precise.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

a skateboard rolling across the street - apex

option number c is the right answer.
