Asquare loop of wire with side length 10 cm is moving to the right with constant speed of 16 m/s. the loop has total resistance of 0.8 ohms. it begins in a region with no magnetic field, then enters a region of magnetic field (wider than 10 cm) with a strength of 0.5 t pointing out of the page. finally it leaves the field. 1. when totally in the field, what is the magnitude of the magnetic flux through the loop? 2. as the loop enters the field, what is the magnitude of the induced emf around the loop?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
