An incandescent bulb has a thin filament of tungsten that is heated to high temperature by passing an electric current. The hot filament emits black-body radiation. The filament is observed to break up at random locations after a sufficiently long time of operation due to non-uniform evaporation of tungsten from the filament. If the bulb is powered at constant voltage, which of the following statement(s) is(are) true?

• The temperature distribution over the filament is uniform

• The resistance over small sections of the filament decreases with time

• The filament emits more light at higher band of frequencies before it breaks up

• The filament consumes less electrical power towards the end of the life of the bulb

Metals are good conductors of electricity because

• they contain free electrons
• the atoms are lightly packed 
• they have high melting point
• all of the above

Large transformers, when used for some time, become very hot and are cooled by circulating oil. The heating of the transformer is due to

• The heating effect of current alone
• Hysteresis loss alone
• both the heating effect of current and hysteresis loss
• intense sunlight at noon

The absorption of ink by blotting paper involves 

• Viscosity of ink
• Capillary action phenomenon
• Diffusion of ink through the blotting
• Siphon action

It is easier to roll a stone up a sloping road than to lift it vertical upwards because

• work done in rolling is more than in lifting
• work done in lifting the stone is equal to rolling it
• Work done in both is same but the rate of doing work is less in rolling
• work done in rolling a stone is less than in lifting it
