Agate at the bottom of a dam is 10 ft tall by 30 ft wide. the specific weight of the water is 62.4 lbf/ft3. if the water is 50 ft deep, the total force on the gate is most nearly:

Determine the maximum r-value of the polar equation r =3+3 cos 0

Describe uniform velocity and variable velocity in short

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?
