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.

A flashlight is used to propel an 85 kg reflective load in space. If the flashlight emits 1W of light in a parallel beam for 1 hour, and the entire beam falls on the surface of the load, find how far the load will have moved at the end of the hour. Assuming it started at rest. (Hint: the force, mass, and acceleration are related through F=m*a; you should also use the physics equation relating position, velocity, and acceleration).

Humans are unable to convert radiant energy from the sun into stored energy that can be usedto do work. Plants, however, obtain their energy from photosynthesis – sunlight is used toconvert carbon dioxide and water into sugars (stored as an energy source) and oxygen.Consider a leaf with a surface area of 2.5 cm2. On a sunny day it might receive sunlight withan average power per unit area of 350 W/m2. Of this incident light, only about 40% is usefulfor photosynthesis. (a) If the process was perfectly efficient (i.e. all the useful radiation was converted tostored internal energy), calculate the increase in internal energy of the leaf in aperiod of one hour. (b) In practice, the overall efficiency of the process (percentage of energy storedrelative to the total incident energy reaching the surface of the leaf) is only about6%. Discuss, in relation to the First Law of Thermodynamics, what happens to theremaining energy?
