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

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
