A 2 cm tall object is 22 cm to the left of a converging lens with a focal length of 12 cm. A second lens (a diverging lens) with a focal length of -4 cm is 28 cm to the right of the first lens along the same optic axis. Required:
a. Calculate the location of the image (call it I1) formed by the lens1.
b. Is image I1 real or virtual?
c. Is image I1 on left side or right side of lens 1?
d. Calculate magnification m1 of lens 1. Is image I1 upright or inverted?

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)

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
