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.

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.

 J    No, because Janice and Alex's added forces is pushing against Becky's force which will push it towards Becky.
