The table re[resents the forces on four objects, with directions.

Object F1 ↑ F2 → F3 ← F4 ↓
W 30 N 20 N 20 N 30 N
X 15 N 35 N 25 N 15 N
Y 60 N 0 N 0 N 60 N
Z 45 N 0 N 22 N 45 N
Which best explains the forces acting on the objects?

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

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?

Which is a substance that can be separated by physical means and is not the same throughout
