1. A flux of 1.5 mWb, linking with a 250 turn coil, is uniformly reversed in a time of 0.02 s. Calculate the value of the emf so induced.
2. A coil of 2000 turns is linked by a magnetic flux of 400 μWb. Determine the emf induced in the coil when
(a) this flux is reversed in 0.05 s, and
(b) the flux is reduced to zero in 0.15 s.
One of the firm's suppliers discounts prices for larger quantities. The first 1000 parts are $13 each. The next 2000 are $12 each. All parts in excess of 3000 cost $11 each. What are the average cost and marginal cost per part
