One day Prema went to her friend's house. As she was climbing the stairs, she saw that a person was hypnotising a lady with a pendulum moving to and fro. The lady in haziness was giving her gold bangles to that person. Prema immediately went towards them and scolded the person who was robbing the lady. She threw his pendulum, called the police and handed him over to the police. The lady when came out from the state of hypnotism thanked Prema. (i) Mention the length of a simple pendulum which ticks seconds. (ii) State the moral that you get from the incident. (iii) Name the type of motion that pendulum shows.

Suppose some electricity is flowing through a long straight wire without any insulating coating that gives an electric shock to a person at rest relative to the wire on touching it. Is there a speed with which if the person runs along the wire in the direction of current flowing such that he/she does not experience any shock?
It is an excellent, thought-provoking question! Suppose a person runs along the direction of electron motion with the same speed of an electron. Then for him, electrons are at rest means zero current in...
