example problems of work and measurement of work

Let us now discuss the conditions to be satisfied for work to be done. From the above examples, it is clear that work is said to be done when a force acts on an object and the point of application of the force moves in the direction of force. Hence, the essential condi..

Work is said to be done when a force acts on an object and the point of application of the force moves in the direction of force. Conditions to be satisfied for work to be done: Some force must act on the object The point of application of force must move in the direction of for..

The transference of energy may take place as work if the system and surroundings have different pressures. For e.g., suppose a gaseous system is enclosed in a cylinder fitted with a movable piston. If pressure of the system is higher, the piston will be pushed up until the pressure of th..

H 2 and O 2 are bubbled through a porous carbon rod into concentrated NaOH. Catalysts are present in the electrodes. ..

The various forms of biomass are mixed with an equal quantity of water in the mixing tank. This forms the slurry. The slurry is fed into the digester through the inlet chamber. When the digester is partially filled with the slurry, the introduction of slurry is stopped and the plant is left..

When the circuit is completed, a deflection is observed in the (G) towards the zinc electrode indicating that the e - are flowing from the Zn electrode to Cu electrode. Al the Zn electrode, oxidation takes place. The 'e' removed or lost or retained by the metal move through the material of the ..

Ammonium chloride, splits into ammonium and chloride ions. The chloride ions (Cl - ) migrate to the zinc rod and deposit their negative charge at the zinc rod. Hence zinc becomes negatively charged and the reactions takes place in which zinc is converted to zinc chloride. The ammonium ions migrate..

The plane of the coil is horizontal and the split ring S 1 touches the brush B 1 while the split ring S 2 touches the brush B 2 . The brush B 1 is connected to the anode of the d.c. battery while the brush B 2 is connected to the cathode. The current flows in the coil in the direction ABCD. The arm..

Slurry (mixture of equal quantities of biomass and water) is prepared in the mixing tank. The prepared slurry is fed into the inlet chamber of the digester through the inlet pipe. The plant is left unused for about two months and introduction of more slurry is stopped. During this period..
