A 3 kg cart (cart A) is released from the top of a ramp, as shown below. The cart travels down the curved part of the ramp (section 1) and travels on a frictionless horizontal surface (section 2). Cart A then collides with a second cart (cart B), which has a mass of 2 kg. Cart A Section 1 Cart B Section 2 Section 3 (a) Is the impulse of cart A positive, negative, or zero as it travel down the ramp in section 1? Briefly justify your answer.

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?
