A cylindrical container has a tiny hole at the bottom. The container is initially filled to its brim with water. If T is the time taken for it to be completely emptied, the graph of the height of the water column as a function of time is closest to which shape?
- 1A parabola opening upwards, reaching zero height at t = T with zero slope✓
- 2A curve that is concave upwards (decreasing rate of height drop)
- 3A step function
- 4A linear decreasing line
Correct answer
A parabola opening upwards, reaching zero height at t = T with zero slope
