Read each question carefully. For a multiple-choice question, determine the best answer to the question from the four answer choices provided. For a griddable question, determine the best answer to the question. Then fill in the answer on your answer document.
1 An atom is shown below.
Which statement below best describes where subatomic particles are located in the atom?
A Electrons are in the nucleus and have a negative charge.
B Protons and neutrons are in the nucleus and both are positively charged.
C Neutrons are in the nucleus and provide no mass to the atom.
D Protons are in the nucleus and provide a positive charge to the atom.
2 Becky was trying push a box to the other side of her bedroom. Her sisters, Janice and Alex, decided to help her.
Are Janice and Alex helping Becky?
F Yes, because Janice and Alex's added forces will help push the box further faster.
G No, because Becky's force will push the box further faster towards Janice and Alex's forces.
H Yes, because Janice and Alex's forces cancels out the mass of the box.

Answer the following question in the box labeled "Short Answer 1" on your answer document using complete sentences.
Immediately following an earthquake, some large buildings may continue to rock for a period of time. More massive buildings continue to move for longer than smaller buildings. Which Newton's law does this demonstrate? Define the law and justify why this law best explains what is going on in the example.
