1. Which of these best explains the student’s data? A The speed of the cart decreases as the cart rolls down the ramp because of friction between the cart and the ramp. B The speed of the cart increases as the cart rolls down the ramp because the force acting on the cart is greater than the force of gravity. C The speed of the cart increases as the cart rolls down the ramp because the forces acting on the cart are unbalanced. D The speed of the cart decreases as the cart rolls down the ramp because the forces acting on the cart are balanced. 2. A skydiver jumps from an airplane and opens his parachute. At some point during his fall, the downward force of gravity on the skydiver is equal to the upward force of drag on the parachute. Which of the following best describes the skydiver's motion at this point? A The skydiver is moving at a constant speed. B The skydiver is decreasing in speed. C The skydiver is gaining speed downward. D The skydiver is moving from side to side.

The diagram illustrates — A the cause of Earth’s seasons B the length of time of Earth’s rotation C the cause of Earth’s ocean tides D the lunar phases that are seen on Earth

1. Although atoms cannot be seen, their mass can be measured. Which subatomic particles are primarily responsible for giving an atom its mass? A Protons only B Electrons and neutrons C Neutrons only D Protons and neutrons 2. Draw a BOHR model for the element BORON

1. Serotonin is a chemical substance that acts as a neurotransmitter. It helps relay messages in the human brain. The formula for one molecule of serotonin is shown below. C 10 H 12 N 2 O How many atoms in all are in two molecules of serotonin? 2. Which two atoms are of elements in the same group in the periodic table? A Atom 1 and Atom 2 B Atom 1 and Atom 4 C Atom 2 and Atom 3 D Atom 3 and Atom 4

1. A magician performs a trick where the tablecloth is quickly removed from the table, while all of the items on the table stay in the same place. Which statement below accurately describes the reason that the items remain on the table? A The mass of the items on the table is so small that no force was applied when the tablecloth was pulled out from under the items. B The direction of the force applied to the tablecloth was down towards the ground, so the items accelerated down towards the table until they rested on the table. C The action force of the moving tablecloth caused a reaction force from the items on the table, so the forces in the items remained balanced and the items remained at rest on the table. D The moving tablecloth did not apply much force to the items on the table, so the forces on the items remained mostly balanced allowing the items remained at rest on the table.

A magician performs a trick where the tablecloth is quickly removed from the table, while all of the items on the table stay in the same place. Which of Newton’s laws best describes the behavior of the tablecloth and the glass on the table? A Tablecloth: Law of force and acceleration; Glass: Law of inertia B Tablecloth: Law of inertia; Glass: Law of force and acceleration C Tablecloth: Law of force and acceleration; Glass: Law of action-reaction D Tablecloth: Law of action-reaction; Glass: Law of force and acceleration
