Drops of water from a cracked gutter fall past the window of an IGCSE Physics students room,
Question:
Drops of water from a cracked gutter fall past the window of an IGCSE Physics student’s room, as shows in the diagram.
The student uses a digital stopwatch to find the time between one drop and the next. To do this he
- sets the stopwatch to zero, then,
- starts the stopwatch as a drop comes into view at the top of the window, then,
- stops the stopwatch 40 drops later
The appearance of the stopwatch after 40 drops is shown below.
a. State the reading on the stopwatch (in s).
b. Calculate the time interval between one drop and the next.
c. Explain why it is better to time 40 intervals than to time just 1 interval.
d. Using the first diagram, estimate the time for a drop to fall from the top of the upper window to the ground.
e. The first diagram shows that the drops get further apart as they get closer to the ground. Explain why this happens.
Step by Step Answer:
a The reading of the stopwatch is 136 Sec b It takes 136 Sec for 40 drops to f...View the full answer
