Compression of human bone. The bulk modulus for bone is 15 GPa. (a) If a diver-in-training is put into a pressurized suit, by how much would the pressure have to be raised (in atmospheres) above atmospheric pressure to compress her bones by 0.10% of their original volume? (b) Given that the pressure in the ocean increases by 1.0 × 10 4 Pa for every meter of depth below the surface, how deep would this diver have to go for her bones to compress by 0.10%? Does it seem that bone compression is a problem she needs to be concerned with when diving?

6. 6. There are 1000 turns on the primary side of a transformer and 200 turns on thesecondary side. If 440 V are supplied to the primary winding, what is the voltageinduced in the secondary winding? Is this a step-up or step-down transformer?
7. 80 V are supplied to the primary winding of a transformer that has 50 turns. If thesecondary side has 50,000 turns, what is the voltage induced on the secondary side?Is this a step-up or step-down transformer?
8. There are 50 turns on the primary side of a transformer and 500 turns on thesecondary side. The current through the primary winding is 6 A. What is the turnsratio of this transformer? What is the current, in milliamps, through the secondarywinding?9. The current through the primary winding on a transformer is 5 A. There are 1000turns on the primary winding and 20 turns on the secondary winding. What is theturns ratio of this transformer? What is the current, in amps, through the secondarywinding?
