Question
How does the sound produced by a vibrating object in a medium reach your ear?
✓
Answer
When an object vibrates, it forces the neighbouring particles of the medium to vibrate. These vibrating particles then force the particles adjacent to them to vibrate. In this way, vibrations produced by an object are transferred from one particle to another till it reaches the ear.

In an experiment to measure his power, a student records the time taken by him in running in a flight of steps on a staircase. Use the following data to calculate the power of the student: Number of steps = $28$ Height of each step = $20cm$ Time taken = $5.4s$ Mass of student = $55kg$ Acceleration = $9.8ms^{-2}$ Due to gravity.
