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

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
