A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

asthenosphere and convection

probably not if net force is zero

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

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
