What is the relationship between supernovae and star formation? -Matter ejected into space during supernovae forms new stars.
-Stars are born when supernovae initiate nuclear fusion within clouds of space dust and
gas
-Supernovae mark the absolute end of a star; the star's matter is destroyed during the
explosion, so that no more stars can form from it.
-Supernovae produce black holes, in which clouds of space dust and gas are exposed to
tremendous pressure; these clouds eventually condense to form new stars.

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

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?
