Without air resistance, a kicked ball would reach a
maximum height of 6.7 meters and land 38 meters
away. with air resistance, the ball would travel
(1) 6.7 m vertically and more than 38 m
horizontally
(2) 38 m horizontally and less than 6.7 m
vertically
(3) more than 6.7 m vertically and less than

The correct answer would be

(4) less than 6.7 m vertically and less than 38 m horizontally

In fact, air resistance points always against the direction of motion of the ball. This means that air resistance causes a deceleration both on the vertical and the horizontal axis: due to this deceleration, the maximum height on the vertical axis and the maximum distance on the horizontal axis will decrease.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
