Ball 2 momentum after collision: 4 kg m/s This table shows the exchange of momentum for Ball 1, which was traveling at 10 kg m/s when it hit Ball 2, which was stationary. The momentum of Ball 1 after the collision is A) 4 kg m/s. B) 6 kg m/s. C) 10 kg m/s. D) 14 kg m/s.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

the correct choice is a .

do not post any more test or exam questions on

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
