Part Two Question One: True or False. Correct the false statements. (615 90 Points 1.1 There is only one system of measurement. 1.2 Units of measurements are essential to produce accessible result of measurement by different users and devices in different places and times. 1.3 The dimensions of acceleration are: M L1 T 1.4 75,642,000,000 in scientific notation is expressed as: O.75642 E11 1.5 25.21, 25.91, 25.87, and 25.47 are of high accuracy and less precision. 1.6 29.3, 28.9, 21.8, and 25.47 are of high precision and less accuracy C) Question Two: (30 Points) Knowing that 1 m 100 cm & 1 kg 1000 g &1 hr 3600s, convert Kg.m2 hr2 to g.cm2s Question Three: Choose the correct answer(s) (3 10 30 Points) 3.1 9,056,000,000,000 Hz can be expressed in SI prefixes as 3.2 0.0000239 in scientific notation is expressed as: 3.3 On measuring a rod of length 17 cm, the set of readings 13.5, 20.2,9.1, and 11 are: a. 9,056,000 M b. 9,056 KM c.9.056 kG d.9.056 T a. 0.00 239 E-2 b. 0.239 E-4 c. 2.39 E-6 d. 2.39 E-5 a. Of high accuracy and low precision. c. Of both high accuracy and precision. b. Of high precision and low accuracy. c. Of neither accuracy nor precision. Question Four: Change the given quantities to required forms 4.1 5.0 x 10-7m. to nano metre. 4.2 1 x 10 s. to prefix format 4.3 12300000 Hz. to GHz 4.4 236000 J to MJ 4.5 1 M W to KW 4.6 1nm into pm. (6*10 60 points)Explanation / Answer
1.1) false, there are various systems of measurements like MKS, SI, FPS CGS etc
2) true
3) false, acceleration dimension is MLT^-2
4) false, it should be 7.56427 10^10
5) false, it is example of high accuracy and high precision
6. False, as the maynitudes of values are too apart from each other hence there is a case of accuracy but there is no precision.

Plz post other problems seperately.
Commemt in case any doubt.. good luck
