Coordinate systems all centred at the same origin x = y = z = 0: b=-p-20+2, c=37 +30-2φ where i, j, k are cartesian, ρ, φ,2 are cylindrical, and t, θ, φ are spherical. (a) draw a picture with all three vectors. what are their magnitudes? (b) what are the dot products a. b, a c, and b c? (c) what are the cross products a × b, a × c, and b x c?

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
