If you are on the top of a mountain and drop an apple, it will fall
to the ground, even though the apple is gravitationally
attracted to you. Why?
Earth is larger and has a much stronger
gravitational pull
b Apples always fall down
Centrifugal forces pull the apple to the Earth and
that is stronger than your gravitational pull
None of these

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions

In a hydrogen molecule there are a total of four charges, 2 protons in the two nuclei, and 2 electrons. how many unique charge-pairs are there (without double counting)?

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
