- Show that at 3000°K, the chemical potential μ for aluminium differs from μ0 by less than 0.1 percent. (μ0=11.7 eV)#14: The Cassini spacecraft that visited Saturn and its moons did more than take pretty pictures; it also returned physical data. Saturn’s moon Titan has a substantial atmosphere, and Cassini went close enough to detect atoms and molecules from Titan’s atmosphere. It measured the atmospheric composition with a time-of-flight mass spectrometer. Ionized atoms and molecules were accelerated through a 30 kV potential difference and then sent through a chamber of length 18.8 cm. The time to travel the length of the chamber was measured, with heavier particles taking longer times. What is the travel time for a singly ionized molecule of water?A specimen of a 4340 steel alloy having a plane strain fracture toughness of 45 MPa sqrt(m) (41 ksi sqrt(in)) is exposed to a stress of 1000 MPa (145,000 psi). Will this specimen experience fracture if it is known that the largest surface crack is 0.75 mm (0.03 in.) long? Why or why not? Assume that the parameter Y has a value of 1.0.
