The angle of 1' (minute of arc) in radian is nearly equal to

In an experiment, four quantities a, b, c and d are measured with percentage error 1%, 2%, 3% and 4%, respectively. Quantity P is calculated as follows:

$P=\frac{a^3{b}^2}{cd},\%$ error in P is

A student measured the diameter of a small steel ball using a screw gauge of least count 0.001 cm. The main scale reading is 5 mm and zero of circular scale division coincides with 25 divisions above the reference level.

If screw gauge has a zero error of -0.004 cm, the correct diameter of the ball is

In an experiment, the percentage of error occurred in the measurement of physical quantities A, B, C and D are 1%, 2%, 3% and 4%, respectively. The maximum percentage of error in the measurement X, where

$X=\frac{A^2{B}^{1/2}}{C^{1/3}{D}^3}$ , will be

A screw gauge has least count of 0.01 mm and there are 50 divisions in its circular scale. The pitch of the screw gauge is

Time intervals measured by a clock give the following readings: 1.25 s, 1.24 s, 1.27 s, 1.21 s and 1.28 s 

What is the percentage relative error of the observations?

A screw gauge gives the following readings when used to measure the diameter of a wire

Main scale reading : 0 mm

Circular scale reading : 52 divisions

Given that 1 mm on main scale corresponds to 100 divisions on the circular scale. The diameter of the wire from the above data is

The errors in the measurement which arise due to unpredictable fluctuations in temperature and voltage supply are

A metal wire has mass $(0.4\pm 0.002)$ g, radius $(0.3\pm 0.001)$ mm and length $(5\pm 0.02)$ cm. The maximum possible percentage error in the measurement of density will nearly be

Taking significant figures into account, what is the value of 9.99 m-0.0099 m?
