2. You are hanging out with your friend Angel, and you decided to warm up some snacks in the microwave. Angle then tells you that he doesn't microwave his food because he read in an article that microwave radiation is even more dangerous than being exposed to UV light because of the high levels of energy in microwave radiation. You disagree with you friend and determine the energy of both types of electromagnetic radiation to prove him wrong. Assume that microwaves have a frequency of 520 MHz and that UV light has a frequency of approximately 780 THz. A. Could you tell if Angel is wrong without any mathematical process, given only the frequencies above? Explain B. Calculate the energy of photons of each type.

smoke particles in air typically have masses of the order of 10^-16 kg. The rapid, irregular motions of these particles caused by collisions with air molecules can be observed with a microscope. Assume a particular type of smoke particle has a mass of 3.00 x10^-16 kg and is in a room with a temperature of 300 K. a) if instead you were considering a hydrogen gas molecule (m= 3.34x10^-26 kg) at 300 K, would the average translational kinetic energy be larger than, smaller than or equal to that of the smoke particle? b) would the rms speed of the hydrogen atom be larger than, smaller than, or equal to that of the smoke particle?
Dimensional Analysis is a way of doing numerical "book-keeping" when converting quantities or performing calculations. • When converting quantities from one unit to another, conversion factors are used. Solving with Dimensional Analysis and Multiple Units: If I am in Canada where the price of gas is $1.022 USD·L1, how much will it cost me to fill up my gas tank if I travelled 125 km? • Let's also assume that my car gets an average of 30.0 miles/gallon.
