If an object moves in a circular path with uniform speed, he motion is called uniform circular motion. Exercises 1. An athlete completes one round of a circular track of diameto 200 m in 40 s. What will be the distance covered and the displacement at the end 2 minutes 20 s ? 2. Joseph jogs from one end A to the other end B of a straight 300 m road in 2 minutes 30 seconds and then turns around Views: 5,142 3 : 8. If a sample of CO 2 ​ contains .

Q. Why was Thomson’s Model of an atom failed? i. It could not explain the screening of negative charges from that of positive ii. It did not tell about the presence of electrons iii. It did not give an idea about the position of the nucleus iv. It explained the atom as a whole to be electrically neutral.
