The precision scientific instrument company manufactures thermometers that are supposed to give readings of 0degreesc at the freezing point of water. tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below 0degreesc (denoted by negative numbers) and some give readings above 0degreesc (denoted by positive numbers). assume that the mean reading is 0degreesc and the standard deviation of the readings is 1.00degreesc. also assume that the frequency distribution of errors closely resembles the normal distribution. a thermometer is randomly selected and tested. a quality control analyst wants to examine thermometers that give readings in the bottom 4%. find the temperature reading that separates the bottom 4% from the others. round to two decimal places

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
