A car at the top of the hill with 200 J of energy, and rolls down a frictionless surface. The isolated system consists of the car, hill, and earth. What happens to the energy of the system as the car moves down the hill?
1- the total energy stays the same but is converted from being stored as kinetic energy into elastic potential energy as it moves.
2- The total energy decreases and is converted from being stored as elastic potential energy into kinetic energy as it moves.
3- The total energy stays the same but is converted from being stored as gravitational potential energy into kinetic energy of the car as it moves
4- The total energy decrease and is converted from being stored as gravitational potential energy into kinetic energy as it moves.

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
