Suppose a disk drive has the following characteristics: • 8 surfaces • 843 tracks per surface • 256 sectors per track • 256 bytes/sector • Tract-to-track seek time of 8.3 milliseconds • Rotational speed of 7,200 RPM. a) What is the capacity of the drive? b) What is the access time?

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?
