A resistance R is measured using the connection shown in the below figure. The current measured is 10 A on ranges 100A and the voltage measured is 125 V on 150 V range. The scales of the ammeter and voltmeter are uniform. The total number of scale divisions of the ammeter is 100 and that of the voltmeter is 150. The scale division can be distinguished. The constructional error of the ammeter is ± 0.3% and that of voltmeter±0.4%. The resistance of the ammeter is 0.25 Ω. The possible error in the measurement of R is?

Mr. John is conducting elevator experiments. Bobby stands on a weigh scale and reads the scale while ascending and descending the building. Bobby’s mass is 80 kg. He notices that the scale readings depend on what the elevator is doing. Angular velocity of hour hand watch is double than that of Earth’s rotation. What is the scale reading when John accelerates upward at 0.40 m/s2?
Which of the following statements is/are NOT true with reference to the measurement of earthquakes?  Statements:  I. The Mercalli scale measures the intensity of earthquakes on levels ranging from 1 to 9. II. The Richter scale assigns a numerical value to quantify energy released during an earthquake. III. The Moment magnitude scale is used to determine the size of an earthquake.
Which of the following statements is correct regarding the map scale? I. Representative fraction method of representing the scale is completely independent of unit of measurement. II. Vernier scale and diagonal scale are types of map scales.
Assertion A): U-shaped long-run average cost curve is based on the assumption that economies of scale prevails at small levels of production and diseconomies of scale prevails at larger level of production. Reason R): Decreasing returns to scale arises primarily because as the scale of operation increases, it becomes even more difficult to manage the firm effectively. In the context of the above two statements, which one of the following codes is correct?
