As the captain of the scientific team sent to Planet Physics, one of your tasks is to measure g. You have a long, thin wire labeled 1.64 g/m and a 1.20 kg weight. You have your accurate space cadet chronometer but, unfortunately, you seem to have forgotten a meter stick. Undeterred, you first find the midpoint of the wire by folding it in half. You then attach one end of the wire to the wall of your laboratory, stretch it horizontally to pass over a pulley at the midpoint of the wire, then tie the 1.20 kg weight to the end hanging over the pulley. By vibrating the wire, and measuring time with your chronometer, you find that the wire's second harmonic frequency is 200 Hz. Next, with the 1.20 kg weight still tied to one end of the wire, you attach the other end to the ceiling to make a pendulum. You find that the pendulum requires 314 s to complete 200 oscillations. Pulling out your trusty calculator, you get to work. Part A What value of g will you report back to headquarters?

one of your tasks is to measure g. You have a long, thin
wire labeled 1.64 g/m and a 1.20 kg weight. You have
your accurate space cadet chronometer but, unfortunately,

then attach one end of the wire to the wall of your
laboratory, stretch it horizontally to pass over a pulley at the
midpoint of the wire, then tie the 1.20 kg weight to the end
hanging over the pulley. By vibrating the wire, and

Large quantities of dust should have been left behind after the creation of the solar system. Larger dust particles, comparable in size to soot and sand grains, are common. They create shooting stars when they collide with the earth's atmosphere. But very small dust particles are conspicuously absent. Astronomers believe that the very small dust particles have been blown out of the solar system by the sun. By comparing the forces on dust particles, determine the diameter of the smallest dust particles that can remain in the solar system over long periods of time. Assume that the dust particles are spherical, black, and have a density of 2000kg/m^3. The sun emits electromagnetic radiation with a power of 3.9×10^26W.

how would you solve this? Light is emitted from the light source, reflects from mirror surface X to the plane mirror, and then to the position of surface Z. By the time the light moves from the X to Z position, mirror surface X will have moved to the position of mirror surface Z. The light then continues to the observer. The distances from the light source and the observer to the rotating mirrors are negligible. The distance from the rotating mirrors to the plane mirror is 35.0 km.If the mirrors are rotating at 480 rev/s, the speed of light calculated from the given information is a 7.44 10–9 m/s b 1.34 108 m/s c 2.98 10–8 m/s d 3.36 107 m/s
