which tool would be likely to provide the most accurate measurement of time in a laboratory experiment involving sprinting times of students?\n○ a wall clock\n○ an egg timer\n○ a stopwatch\n○ a calendar
Answer
Brief Explanations:
A stopwatch is designed for measuring short - duration time intervals precisely, which is suitable for measuring sprinting times. A wall clock is not precise enough for short - time measurements in a sprint experiment. An egg timer is usually for a set time and not adjustable for exact sprint times. A calendar is for long - term timekeeping and not relevant for short - time measurements in an experiment.
Answer:
a stopwatch
