Question: Catalina Highway stretches 25 miles (40 km) and the entire mountain range is one of Tucson's most popular vacation spots for cycling, hiking, rock climbing, camping, birding, and wintertime snowboarding and skiing. Near the top of Mt. Lemmon is the town of Summerhaven. In Summerhaven, visitors will find log houses and cabins, a general store, and various shops, as well as numerous hiking trails. Near Summerhaven is the road to Ski Valley which hosts a ski lift, several runs, a giftshop, and nearby restaurant.
Try to answer this question if possible: What is in Ski Valley?
Answer: a ski lift, several runs, a giftshop, and nearby restaurant
Question: Rumors began swirling with regards to bringing the AFL back to Austin and San Antonio, Texas. Both cities have hosted franchises in the past (Austin Wranglers, San Antonio Force and San Antonio Talons), but an AFL spokesman, BJ Pickard, was quoted as saying, "News to me." Announcements have yet to be made on any sort of expansion plans. An expected "big announcement" on Friday, October 30 at a San Antonio Spurs game never came to fruition.
Try to answer this question if possible: Along with the San Antonio Talons, what AFL franchise did San Antonio host at one time?
Answer: San Antonio Force
Question: While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.
Try to answer this question if possible: What is a disadvantage of using inert gas in a light bulb?
Answer: unanswerable
Question: Niels Bohr introduced the first quantized model of the atom in 1913, in an attempt to overcome a major shortcoming of Rutherford's classical model. In classical electrodynamics, a charge moving in a circle should radiate electromagnetic radiation. If that charge were to be an electron orbiting a nucleus, the radiation would cause it to lose energy and spiral down into the nucleus. Bohr solved this paradox with explicit reference to Planck's work: an electron in a Bohr atom could only have certain defined energies En
Try to answer this question if possible: Who modeled the molecule in 1918, challenging Rutherford's model?
Answer:
unanswerable
