Your teacher wants to create a density bottle with three solutions called a, b, and c. Calculate the densities and complete the model of how the three liquid layers will appear once settled show all your work! your teacher put 45 mL of solution a with a mass of 65 grams. Then, put 15 mL of solution b with a mass of 23 g into the bottle. Lastly, they put 100 ml of solution c with a mass of 130 g in the bottle

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)
