A projectile moves down a tube with a velocity of 400. m/s. Calculate the velocity of the normal shock that would precede the projectile. Assume the pressure in the undisturbed air to be 1.00 atm and the temperature to be 25.5 oC. Then determine how fast would the projectile have to be moving in order for the shock velocity to be twice the projectile velocity

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

multiply 2kg by latent heat of vap

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
