An airliner is cruising at a ground speed of 450 knots. A flight attendant, serving drinks, accidentally knocks a bottle off her cart. The distance from the top of the cart to the deck is 3.5 ft. Using the Earth as the frame of reference, how many feet does the bottle travel between the moment it falls off the cart, and when it hits the airplane's deck? Report your answer to the nearest three decimal places.
A parallel plate capacitor has a left plate with a positive charge of +Q and a right plate with a charge of -Q. The magnitude of the electric field between the plates is 100 V/m The plates each have an area of 2.0x10-3 m2 with a spacing of plate..
