Write an expression for B⃗ (d), the magnetic field a distance d above the xy plane of the sheet. Use μ0 for the permeability of free space. Express the magnetic field as a vector in terms of any or all of the following: d, I, N, a, μ0, and the unit vectors i^, j^, and/or k^.

if they have a finite resultant

do you have a formula possibly

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
