A charge of 661 nC and mass m = 11 g is suspended from a 1.1 m long string. When the string makes an angle of 16o to the vertical, the charge is in equilibrium. The charge is acted upon by another charge of 622 nC fixed in space. What is the tension in the string?

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.
