A moving coil instrument has a resistance of 70 Ω and gives full scale deflection of 100 scale divisions for a current of 1 mA. The instrument is connected in parallel with a shunt of 30 Ω resistance and this combination is then connected in series with a load and supply. Determine the current in the load when the instrument gives an indication of 80 scale divisions.

Four students are looking at a map of India with scale of 1 cm = 100 km. Student 1: Let's draw a large scale map our colony now. Student 2: Why do you feel we need a large paper to draw our colony? A small one is enough. Student 3: Large scale does not mean large paper. We need to change the scale. Let's make it 1 cm = 500 km. Student 4: No no, since we only need to draw our colony, a centimeter can show much less distance. Arrange the four students in increasing order of the conceptual clarity (i.e. from least clear to most clear)
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 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?
