A honey bee of mass 135 mg has accumulated a static charge of +1.6 pC. The bee is returning to her hive by following the path shown in the figure. Because Earth has a naturally occurring electric field near ground level of around 100 V/m pointing vertically downward, the bee experiences an electric force as she flies. What is the change in the bee’s electric potential energy, Δ?electric, as she flies from point A (0 m,0.3 m) to point B...

1.An ionic compound made Mg and F must be MgF2. Why is this case? In your answer consider the charge on Mg and F, based on their potion in the periodic table. 2. The correct name for Cu2+ and Cl- forming CuCl2 is Copper (II) Chloride, however Ba2+ and Cl- forming BaCl2 is not written barium (II) Chloride (instead written as just barium chloride). Why? (Hint- think about where copper is in the periodic table. 3. Notice question 2 above,...

A penny, which has a mass 2.5 grams and is made of zinc, is released from rest just beneath the surface of some 80 proof vodka. (80 proof means 40% ethyl alcohol and 60% water, by volume). If the height of the vodka in the bottle is 25cm, how long will it take for the penny to reach the bottom? (Ignore drag and other frictional effects. Assume the only effect of the fluid is buoyancy.)
