What is the unit vector along ⃗ = hat − hat + hat ?

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

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.

i already answered it by 34/s

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
