If you choose to drive to school tomorrow, you will inevitably have to make a right or left turn along the way. Say you're coming to school via Melrose avenue, heading West toward Fairfax.

As you reach Orange Grove Ave the coast is clear and you turn left into the driveway, but you notice that you're going too fast and the huge bump in the middle of the driveway may end up damaging the underside of your new Honda Civic. You decide to slow down. This decision is most adequately characterized as a...achange in accelerationbchange in displacementcchange in velocitydchange in speed

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)
