A person measures the depth of a well by measuring the time interval between dropping a stone and receiving the sound of impact with the bottom of the well. The error in his measurement of time is δT = 0.01 seconds and he measures the depth of the well to be L = 20 meters. Take the acceleration due to gravity g = 10ms–2 and the velocity of sound is 300ms–1. Then the fractional error in the measurement, δL/L, is closest to Read more on Sarthaks.com – https://www.sarthaks.com/48473/person-measures-the-depth-of-a-well-by-measuring-the-time-interval-between-dropping-stone

A screw gauge with a pitch of 0.5 mm and a circular scale with 50 divisions is used to measure the thickenss of a thin sheet of aluminium. Before starting the measurement, it is found that when the two jaws of the screw gauge are brought in contact, the 45th division coincides with the main scale line and that the zero of the main scale is barely visible. What is the thickness of the sheet if the main scale reading is 0.5 mm and the 25th division coincides with the main scale line?
