A worker is pushing a cart along the floor. At first, the worker has to push hard in order to get the cart moving. After a while, it is easier to push and he keeps it going at a uniform speed. Finally, the worker has to pull back on the cart in order to bring it to a stop before it hits the wall. The force exerted by the worker on the cart is purely horizontal. Take the direction the worker is going as positive. Below are shown graphs of some of the physical variables of the problem. Match the graphs with the variables in the list at the left below. AND PLEASE EXPLAIN WHY YOU CHOSE THIS. You may use a graph more than once or not at all. (Note: the time axes are to the same scale, but the ordinate ("y-axes") are not, and t = 0 is just as the cart starts moving.)1) Friction On The Cart. 2)Force exerted by the worker on the cart. 3) Net force experienced by the cart. 4) Acceleration by the cart. 5) Velocityy on the cart

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?
