QUESTION: 6

When a current flows through a conductor its temperature

Solution:

As we know,

Power=I^{2}R

Therefore, this power is released in the form of heat in the conductor and this heat increases the temperature of the conductor.

Hence, temperature increases.

QUESTION: 14

On the horizontal surface of a truck (μ=0.6), a block of mass 1 kg is placed.If the truck is accelerating at the rate of 5 m/sec^{2} then frictional force on the block will be

Solution:

If the block has to move, it should overcome static frictional force which is μmg = 0.6×10 = 6N

As the truck is moving with an acceleration, a pseudo force acts on the block which is ma = 1×5 = 5N

As this force is not enough for the block to move, an equal frictional force acts in the opposite direction which is equal to 5N
