2) This is a kind of electroscope student made in science class to study charges
Student Procedure:
-Tear off two pieces of tape, each 4 inches (10 cm) long.
-Press each piece firmly on the work table leaving one
end of each tape piece sticking up as a handle.
-Quickly pull the tapes from the table and stick one piece
on the arm of a straw in one film canister, and the other
piece on the arm of a straw in the other
film canister.
--Move the canisters so the two pieces of tape are face to
face, about 6 inches apart.
-Slowly move the canisters closer together.

B) Pushing forces can work at a distance
Like charges exert a pull from a distance.
Eliminate

Arowboat passenger uses an oar to push the boat off the dock by exerting a force of 40n for 3.0s. what impulse acts on the boat.

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .
