Lithium hydride, 7LiH, is a potential fuel for fusion reactors because it is one of the few compounds of very light elements that exists as a solid, and is therefore more dense than gaseous fuels even under extreme conditions. LiH in the gas phase has a pure rotational spectrum consisting of lines spaced by 15.026 cm-1.
(a) calculate the bond distance of LiH;
(b) Determine the first four absorption lines in the pure rotational spectrum of LiH in units of GHz;
(c) Determine the most populated level, Jmax for a sample of LiH at 298 K and 1000 K.
During a particular car crash, it takes just 0.18 sec for the car to come to a complete stop from 50 km/hour. At what rate is the car accelerating during the crash
the motion of a 25.0kg mass on the end of a string is uniform motion. the magnitude of the tangential velocity of the mass is 5.0m/s. calculate the angular momentum of the mass
A mass m1 = 1 kg rests on top of a mass m2 = 5 kg which is attached to a spring (k = 50 N/m), Determine the maximum amplitude of the motion such that the top mass does not slip

Two divers jump from a 5-m platform. One jumps upward at 1.90m/s , and the second steps off the platform as the first passes it on the way down. By how much does the first diver hit the water first (seconds)
An object falls because of gravity at the rate of -920 cm/s2 (- sign is indicative of a downward direction) for 10.00 Seconds. If it starts from rest (vo = 0) and its position starts from do= 0.0, where is it 10.00 Seconds later.
