You're on a roll — here are the solutions to the exercise questions: A. Darken the circle for correct option in OMR Sheet: 1. d) Face Explanation:* Finger, hand, and foot were historical units of length. "Face" is not a unit of length. 2. c) 0.025 km Explanation:* 2.5 m = 2.5 × 100 cm = 250 cm 2.5 m = 2.5 × 1000 mm = 2500 mm 2.5 m = (2.5)/(1000) km = 0.0025 km Therefore, 0.025 km is not equal to 2.5 m. 3. d) rectilinear motion Explanation:* Motion along a straight track is specifically called rectilinear motion. 4. b) random Explanation:* A kite's movement in the sky is often unpredictable and irregular, fitting the description of random motion. 5. a) periodic Explanation:* Periodic motion is defined as motion that repeats itself after a fixed interval of time. B. Fill in the blanks: 1. The early people used modes of transport to help them move from one place to another. 2. The invention of the wheel proved to be a revolution in our means of transportation. 3. One metre is equal to 1000 millimetre. 4. Rest and motion are relative terms. 5. When you push a box on the floor, it undergoes translatory motion. C. Write 'T' for True and 'F' for False statements: 1. When you travel by a train or a car, the person sitting next to you is at rest with respect to you. T 2. The motion of a swing is an example of rectilinear motion. F Explanation:* The motion of a swing is oscillatory, not rectilinear. 3. The motion of a spinning top is an example of rotatory motion. T 4. The motion of a pendulum is an example of oscillatory motion. T 5. The motion of a wheel of a moving car is an example of rotatory motion.
