You are working as a physics lecture demonstration supervisor at a university. One of the professors wants you to build a device that will pass current in an axial direction along the metal sides of a soft drink can so that it will crush from the pinch effect. This effect is due to the fact that the small element of current in one section of the can is attracted to the current elements in all the other sections, because all the currents are in the same direction. The professor wants this demonstration to be used in a lecture on currents through plasmas, where the pinch effect is observed to cause particles of the plasma to bunch together. The professor has told you that a pinch effect pressure of 3.22 atm should crush the can. Before determining if the professor's request is feasible, you need to determine what axial current (in A) you need to pass through the 2.98 cm radius can. (Hint: Start by finding the pressure on a very thin strip of the can parallel to the axis.)

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

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.
