Question

b) As compared to a small electric motor, what improvements are made to enhance the
power in commercial motors? (Any2)​

Answer 1

Answer:

The power of the commercial motors is increased in the following ways: (i) Permanent magnet is replaced with electromagnet. (ii) The conducting material of the current carrying coilis manufactured with large number of coils. (iii) The coil is wound on a soft iron core.

Answer 2

The sample space has 6 possible outcomes-

S={1,2,3,4,5,6}.

Let all outcomes are equally likely(fair dice).

Hence Probability of any one outcome occurring= 1/6.

The event that we get that an even number on tossing the die can occur in 3 possible ways.

Let E denote this event.

E={2,4,6}

Now P(E)= 3×1/6=1/3
