Read this excerpt from The Riddle of the Rosetta Stone by James Cross Giblin. Champollion spent almost a year and a half in Egypt. On his return home to Paris, he began the huge job of deciphering and organizing all the material he had gathered. Sad to say, he did not live to see the fruits of his labor. On March 4, 1832, while preparing the results of the expedition for publication, he collapsed and died after a series of strokes. He was only forty-one.

Based on the excerpt, what was the effect of Champollion’s visit to Egypt?

Champollion died at the age of forty-one.
Champollion returned to Paris.
Champollion published a book.
Champollion gathered more knowledge.

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct
