1
Atomic Structure
What happens inside the nucleus when a beta particle is emitted?
2
Atomic Structure and the Development of the Model
What observation showed the nucleus is positively charged and very small?
3
Radioactivity, Half-Life and Nuclear Uses
State one source of natural background radiation and one source of artificial (man-made) background radiation.
4
Forces
A box has a driving force of 250 N forward and friction of 180 N backward. Calculate the resultant force, including its direction.
5
Motion: Speed, Velocity and Acceleration
A ball decelerates uniformly from 18 m/s to 0 m/s over a distance of 2.7 m while being caught. Using (final velocity)^2 = (initial velocity)^2 + 2 x acceleration x distance, calculate its deceleration.
