When metals and nonmetals combined, first there is a complete transfer of charge to form cations and anions to complete their valence shell and increase stability. Then bonds are formed by electrostatic attraction.

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.

Both speed and velocity measure how fast something is moving. however, since speed is not a it does not require a(n question 6 options: a) quantity , unit b) magnitude, unit c) scalar, direction d) vector, direction
