A900 kg car is traveling west at 25 m/s. an suv with a mass of 1,500 kg is traveling at 10 m/s east, heading straight for the car. the car and suv collide and stick together.
a.) momentum of the car before collision=
b.) momentum of suv before collision=
c.) determine the speed of the car and suv after the collision.

Frank just graduated from eighth grade. assuming exactly four years from now he will graduate from high school how many seconds does he have until his high school graduation

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?

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
