Awire, of length l = 4.1 mm, on a circuit board carries a current of i = 1.96 μa in the j direction. a nearby circuit element generates a magnetic field in the vicinity of the wire of b = bxi + byj + bzk, where bx = 4.9 g, by = 2.3 g, and bz = 2.4 g.
a. calculate the magnitude of the magnetic field b, in gauss, in the vicinity of the wire due to the circuit element.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?
