It is required to find the volume of a rectangular block , A vernier calipers is used to measured values are found to be 1.37 cm, 4.11cm and 2.56 cm , respectively . How should we report the result ?

The coefficient of viscosity of a liquid flowing through a narrow tube is given by eta=(pipr^(4))/(8Vl) where r and l are the radius and the length of the tube p is the pressure difference between its two ends and V is the volume of liquid flowing per unit time. Here the values of p,r,V and l are 75 cm Hg, 0.35 cm, 1.5 cm^(3)//s and 20.5 cm. respectively , the errors in their measurement are 0.1 cm Hg. 0.01 cm, 0.1 cm^(3)//s and 0.1 cm. respectively. Estimate the percentage error in the computed value of eta .

The length breadth and thickness of a rectangular strip of metal are 3.335 m,1.025 m and 3.05 cm respectively. Find the area and volume of the strip to correct significant figures.

The length , breadth and height of a rectangular paralelopiped are 11 cm , 9 cm and 6 cm respectively . How many coins of diameter 3 cm and height 1/4 cm can be made from this rectangular paralelopiped ?

The radius of two circles are 2 cm and 4 cm respectively, Let's write the length of their diameter without measuring.

A student performs an experiment of measuring the thickness of a slab with a vernier calliper whose 50 divisions of the vernier scale are equal to 49 divisions of the main scale. He noted that zero of the vernier scale is between 7.00 cm and 7.05 cm mark of the main scale and 23rd division of the vernier scale exactly coninides with the scale. the measured value of the thickness of the given slab using the calliper will be

Thermal capacities of mercury and glass of the same volume are equal. Densities of mercury and glass are "13.6 g.cm"^(-3) and "2.5 g.cm"^(-3) respectively. If the specific heat capacity of mercury is "0.03 cal.g"^(-1).^(@)C^(-1) . Find that of glass.

A solid toy is in the form of a right circular cylinder with hemispherical shape at one end and a cone at the other end. Their common diameter is 4.2 cm and the height of the cylindrical and conical portions are 12 cm and 7 cm respectively. Find the volume of the solid toy. (Use pi= (22)/(7) )
