The great attractor is enigmatic space anomaly that is attracting millions of galaxies toward a dark and mysterious place. our galaxy milky way is moving in its direction with velocity of 75 thousand meters per seconds. milky way's center of mases is =5[gm]i+6[gm]j-1gm]k relative to wilkes university where the unit here is [gm] gazillion meters. the great attractor is acting on milky way with force of f = -71& n]i - 3[gn]j-5[gn]k where the unit is [gn] gazillion newton. find a) the torque due to this force in units of [g2nm] [gazillion square newton meters] b) the angle between force f and the direction of

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?

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)

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration
