Questions at a Glance.
Q11. Diagram shows a fast train. The train moves fast by levitating on the track. The levitation is due to the magnetic forces produced between the electromagnet at the base of the train and the electromagnet on the track. The fast train changes its speed from 0 kilometre per hour to 360 kilometre per hour in 10 s. Calculate the final speed, the acceleration and the distance travelled by the train. You are also required to investigate the characteristics of a fast train, Explain the suitability of each characteristic of a fast train and determine the most suitable fast train which can move with highest speed.

Q12. Diagram in part (a) shows a bat using ultrasonic waves to detect obstacle in front of it. (ii) Explain how the ultrasonic waves are used by the bat to detect the distance of the obstacle. (b) A beam of sonar with speed 1450 m/s sent to a shoat of fish underneath a fishing boat. You are required to calculate the depth of the shoal of fish when the echo returns after some time and the wave length of the sonar waves for a fix value of frequency. (c) Three classrooms in your school are combined to become a lecture hall. You are asked to investigate the design of the sound system to produce better quality of sound. Explain the suitability of each characteristics of the sound system and by giving reasons for your choice, determine the most suitable sound system.
