Why isn’t pluto currently considered a planet?

a. pluto’s orbit around the sun is larger than that of any of the eight planets.

b. pluto is smaller than all of the eight planets.

c. pluto has a moon, charon, which is more than half its size and larger than other planets’ moons.

d. pluto’s gravity is too weak to pull in smaller debris, so it hasn’t cleared its orbital path.

What should the power status of a circuit be when measuring resistance with an ohmmeter?

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)
