(2) Differentiate between speed and velocity. At least 3points?
(3) What is retardation? A 200m long train crosses a 400 m bridge with a
velocity of 36km/h. Find the time taken by the train to cross the bridge?
14) What are the characteristics of matter. At least 4points?.
please help me for all 3 questions
