Which statement correctly describes the location, charge, and mass of the neutrons in an atom?

• The neutrons are outside the nucleus, have no charge, and have no mass.

• The neutrons are inside the nucleus, have no charge, and have mass.

• The neutrons are outside the nucleus, have a negative charge, and have no mass.

• The neutrons are inside the nucleus, have a negative charge, and have mass.

Which statement best describes the movement of the grocery cart?

• The cart moved at a constant rate of speed of .5 m/s

• The cart was stationary and had no velocity.

• The cart moved at a constant rate of speed of 5 m/s.

• The cart had two different velocities during the 20 seconds.

Opposing forces are applied to a 45 kg box as shown. Which statement best describes the acceleration of the box?

• The box does not accelerate, because neither force is strong enough to move the box.

• The box accelerates at 1.33 m/s2 to the right, because the net force is 60 N to the right.

• The box accelerates at 1.0 m/s2 to the right, because the net force is 30 N to the right.

• The box accelerates at 45 m/s2, because the greater force is to the right.
