A Geiger-Mueller tube is a radiation detector that consists of a closed, hollow, metal cylinder (the cathode) of inner radius ra and a coaxial cylindrical wire (the anode)of radius (see figure below) with a gas filling the space between the electrodes. Assume that the internal diameter of a Geiger-Mueller tube is 1.95 cm and that thewire along the axis has a diameter of 0.190 mm. The dielectric strength of the gas between the central wire and the cylinder is 1.25 x 106 V/m. Use the equationain2πrle= to calculate the maximum potential difference that can be applied between the wire and the cylinder before breakdown occurs in the gas.€0AnodeCathode148XYour response differs from the correct answer by more than 10%.

You are using a microscope to view a particle of lycopodium powder suspended in a drop of water on a microscope slide. As water molecules bombard the particle, it "jitters" about in a random motion (Brownian motion). The particle's average kinetic energy is the same as that of a molecule in an ideal gas (K = 3KBT). The particle (assumed to be spherical) has a density of 250 kg/m³ in water at 17ºC. 2 (a) If the particle has a diameter d, determine an expression for its rms speed in terms of the diameter d. (Enter your answer as a multiple of d-³/2. Assume is in m/s and d-3/2 is in m-3/2. Do not include units in your answer.) Vrms d-3/2 Vrms (b) Assuming the particle moves at a constant speed equal to the rms speed, determine the time required for it to travel a distance equal to its diameter.

Given: a sample of copper has a mass of 48.62 g when measured in air and a mass of 43.19 g when measured completely submerged in water. Copper has an atomic number of 29 and an atomic mass of 63.546. You only need to determine the density of the sample and determine the radius of the copper atom.
Please answer all parts: Problem 3: There are lots of examples of ideal gases in the universe, and they exist in many different conditions. In this problem we will examine what the temperature of these various phenomena are. Part (a) Give an expression for the temperature of an ideal gas in terms of pressure P, particle density per unit volume ρ, and fundamental constants. T = ______ Part (b) Near the surface of Venus, its atmosphere has a pressure fv= 91 times the pressure of Earth's atmosphere, and a particle density of around ρv = 0.91 × 1027 m-3.

Part (c) The Orion nebula is one of the brightest diffuse nebulae in the sky (look for it in the winter, just below the three bright stars in Orion's belt). It is a very complicated mess of gas, dust, young star systems, and brown dwarfs, but let's estimate its temperature if we assume it is a uniform ideal gas.

There are two important isotopes of uranium, 235 U and 238 U ; these isotopes are nearly identical chemically but have different atomic masses. Only 235 U is very useful in nuclear reactors. Separating the isotopes is called uranium enrichment (and is often in the news as of this writing, because of concerns that some countries are enriching uranium with the goal of making nuclear weapons.) One of the techniques for enrichment, gas diffusion, is based on the different molecular speeds of uranium hexafluoride gas, UF6 . (a) The molar masses of 235 U and 238 UF6 are 349.0 g/mol and 352.0 g/mol, respectively. What is the ratio of their typical speeds vrms ? (b) At what temperature would their typical speeds differ by1.00 m/s? (c) Do your answers in this problem imply that this technique may be difficult?
