Para asegurar un ajuste perfecto, los remaches de aluminio usados en los aviones se fabrican ligeramente más gruesos que los orificios y se los enfría con hielo seco (CO2sólido) antes de ser introducidos en los orificios. Si el diámetro de un orificio es de 20 mm . Cuál debe ser el diámetro del remache a 20 ºC para que su diámetro sea igual al orificio cuando se enfría a -78 ºC que es la temperatura del hielo seco. coef. del aluminio= 24x10-6ºC-1.

What are the theoretical properties of a gas at a temperature of 0 kelvin?

Looking at this barometer, is the air pressure high or low? what type of weather would you expect? high, bad low, bad high, good low, good

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
