A rectangular container measuring 24 cm 48 cm 55 cm is filled with water. What is the mass of volume of water in kilograms.
A block of mass 3.65kg and density 600 kg/m^3 floats in a bath of oil of density 970kg/m^3. calculate total volume of wood and metal
When 50-ml of a liquid is heated through 20 degree centigrade, its apparent expansion was 0.5 ml. If the coefficient of linear expansion of the container is 9 x 1/1000000 per K, find the coefficient of real expansion of the liquid.
The hydraulic cylinder is subjected to 3 forces. An 8kN force is exerted on cylinder at B that is parallel to the cylinder and points from B towards C. The link AC exerts the force at C that is parallel to the line from A to C. The link CD exerts ..
