Practice calculating percent error: A group of students got the following values for the speed of sound during their lab. Show numbers plugged into the percent error formula. Calculate the percent error. Then circle which groups got within the +/-5% error allowed. Group 1 got 365 m/s Group 2 got 345.1 m/s

Group 3 got 300.5 m/s Group 4 got 339 m/s CAN ANYONE PLEASE HELP ME WITH THIS

Which of the following list the divisions of the geologic time scale in order from longest to shortest

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
