You have been given 1.326071 g of copper from which you are to fashion a wire whose resistance is 2.2619253 ohms. the density of copper is 8900 kg/m 3 and the resisitivity of copper is 1.7 x 10^-8 ohm m. what will the diameter of the wire be that you fashion?

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.

How can you measure the amplitude of a longitudinal wave?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
