Question
A student tries to use the force table with masses: 100 g, 200 g, and 500 g but is unable to put central ring in equilibrium. What has gone wrong? (a) The angles are not set to the right values. (b) All the pulleys are on the same half of the force table. (c) The two lessor masses set opposite the greater mass result in a net force on the ring. (d) The force table was not leveled properly. (e) None of the above. Which of the following are measurement? (a) (9.9 plusminus 3.1) cm^2 (b) (19.0 plusminus 4) seconds (c) (500. plusminus 6) kg/m (d) (5.30 plusminus 0.40)m/s^2 (e) 2.23 m plusminus 0.01 All of the following measurements have 4 significant figures except: (a) 35.70 sec (b) 0.003 kg (c) 1.003 kg (d) 1.300 kg (e) 3000 miles plusminus 1 mile All of the following measurements have 3 significant figures except: (a) 0.300 kg (b) 0.060 cm (c) 4.70 times 10^4 J (d) 4.70 times 10^6 J (c) 3000 miles plusminus 10 miles Which of the following measurements are in their most appropriate form: (a) 7.425 plusminus 3.2 m (b) 9.876, 543, 210 plusminus 21, 648 years (c) 6.541 times 10^3 plusminus 43 seconds (d) 2.222 times 10^-3 plusminus 2.2 times10^-5 radians (e) (0.00 plusminus 0.04) kgExplanation / Answer
