Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

find the resistance of a piece if wire. The piece of wire is my dependent variable throughout the investigation. I changed the length of the wire in order to measure the resistance of each length. Plan In this investigation‚ a simple circuit will be set up to read the voltage and current when the length of the wire changes. The length will range from 10cm-80cm with intervals of 10cm. The length of the wire will be changed by moving the crocodile clip across the wire and checking the measurements with

Mary Emeny’s poem‚ "Barbed Wire‚" depicts war as a negative force‚ destroying every decent aspect of human existence. Written during the Vietnam War‚ the work displays Emeny’s negative views on war. In one way or another everyone experiences and identifies with the presence of war. Although some wars are fought for justifiable reasons‚ every war tears into the lives of those undeserving. The tragic effects of war consume the innocent creating an unconquerable path of entanglement. The physical
