In an experiment, a metal ball is dropped into a viscous liquid. The terminal velocity of the ball in the liquid is measured. The experiment is repeated four times. For each repeat, a change is made to one of the following. 1 the density of the metal of the ball 2 the height from which the ball is dropped 3 the density of the liquid 4 the depth of the liquid Which two changes separately affect the terminal velocity of the ball in the liquid?

1. A1 and 2
2. B1 and 3
3. C2 and 4
4. D3 and 4
