B) A generator supplies 100 V to a transformer's primary coil, which has 50 turns. If the sec- ondary com has 500 turns, i wiat is the secondary voltage? If the load, with resistance of 312, is
connected on the secondary coil, what current will flow on (ii) secondary, and (iii) primary coils? (iv)
Based on your answers in (i) (ii) and (iii), what type of transformer is in question? (5 marks

Asmall metal bar, whose initial temperature was 10° c, is dropped into a large container of boiling water. how long will it take the bar to reach 70° c if it is known that its temperature increases 2° during the first second? (the boiling temperature for water is 100° c. round your answer to one decimal place.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)
