Question

e. How long will it take for a boy cycling at 5 m/s to cover a distance of 250 metre. 4. a. What are the factors affecting potential energy of an object placed at a height and how they affect? b. Define interconversion of energy c. State law of conservation of energy d. Two blocks of masses 30 kg and 50 kg are placed at the same height above the ground. Which of the two has greater potential energy and why? e. What is the full form of CNG?​

Answer 1

e.it takes 50secs to cover 250 metres by the boy .4. the potential energy from height also includes gravitational pull.d.the block of 50kgs will have greater potential energy because the heavier the object is the more the gravitational pull /energy acts e. CNG- compressed natural gas
