A plate on square base made of brass is of length x cm and width 1mm. The plate weighs 4725 gm. If 1 cubic cm of brass weighs 8.4 gram, then the value of x is :

A plate has a length ( 5pm 0.1 ) cm and breadth (2pm 0.01) cm . Then the area of the plate is

A rectangular marble stone 28cm wide and 5cm thick weighs 112kg. If 1 cubic cm of marble weighs 25gm, then the length of given stone is

Two wires of diameter 0.25 cm, one made of steel and the other made of brass are loaded as shown in figure. The unloaded length of steel wire is 1.5 m and that of brass wire is 1.0 m. Compute the elongations of the steel and the brass wires .Young's modulus of steel is 2.0 xx 10^(11) Pa and that of brass is 9.1 xx 10^(11) Pa.

A hollow iron pipe is 21 cm long and its exterior diameter is 8 cm. If the thickness of the pipe is 1 cm and iron weighs 8g//cm^(3) , then the weight of the pipe is (Take pi = (22)/(7) )

A hollow iron pipe is 21cm long and its external diameter is 8cm. If the thickness of the pipe is 1cm and iron weighs 8g/cm3, then the weight of the pipe is (a) 3.6kg (b) 3.696kgquad (c)36kg (d) 36.9kg

Two wires of diameter 0.25 cm , one made of steel and other made of brass, are loaded as shown in the figure. The unloaded length of the steel wire is 1.5 m and that of brass is 1.0 m . Young's modulus of steel is 2.0 xx 10^(11) Pa and that of brass is 1.0 xx 10^(11) Pa. Compute the ratio of elongations of steel and brass wires. (/_\l_("steel"))/(/_\l_("brass"))=?

A hollow copper pipe is 22 cm long and its external diameter is 28 cm.If the thickness of the pipe is 3 cm and iron weighs 8.5 g/ cm^3 , then the weight of the pipe is closest to:

If length and breath of a plate are (40 +- 0.2)cm and (30 +- 0.1 ) cm , the absolute error in the meaurement of area is
