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?

Select for each of the following statements whether it is correct or incorrect. (a) in an isothermal expansion of an ideal gas. (b) the temperature remains constant. (b) the pressure remains constant. (c) there is work done by the gas. (d) there is heat added to the gas. (e) the change in internal energy equals zero.

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. in a typical strike, the chameleon's tongue accelerates at a remarkable 220 m/s2 for 20 ms, then travels at constant speed for another 30 ms.

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
