The demand for dental services is unit elastic. The elasticity of demand is measured by the price elasticity of demand, which is defined as the percentage change in quantity demanded divided by the percentage change in price. The formula for price elasticity of demand is: In this case, the quantity of dental services demanded increases by 10 percent when the price falls by 10 percent. Therefore, the price elasticity of demand is: Since the absolute value of the elasticity is 1, the demand is unit elastic. This means that the percentage change in quantity demanded is exactly equal to the percentage change in pri

What is the effect of a lump-sum franchise tax of t on the quantity at which a firm's after-tax average cost LOADING... curve reaches a minimum? (Assume that the firm's before-tax average cost curve, AC Subscript BTACBT, is U-shaped.) Part 2 Determine the average tax per unit of output. Part 3 The average tax per unit of output, q, is average taxequals=StartFraction t Over q EndFractiontq. (Properly format your expression using the tools in the palette. Hover over tools to see keyboard shortcuts. E.g., a fraction can be created with the / character.) Part 4 For example, if the firm sells only 1 unit of output, then its average cost in taxes is equal to tt. Part 5 If the firm sells 250250 units of output, then its average cost in taxes is equal to enter your response here. (Properly format your expression using the tools in the palette.)

Question 2: (8 marks) a) Design a combinational circuit with three inputs, x, y, and z, and three outputs, A, B , and C. When the binary input is even (0, 2, 4, or 6) the binary output is two greater than the input. When the binary input is odd (1, 3, 5, or 7) the binary output is one less than the input. Write the simplified output equations. (5 marks) b) Implement the following Boolean function: F(A, B, C) = \prod(2, 5, 6) with a 2 \times 1 multiplexer. (3 marks)

5.) Bohr's model of the hydrogen atom included a derivation in which he found the wavelengths emitted should follow the equation $\frac{1}{\lambda} = \frac{2 \pi^2 m k^2 e^4}{ch^3} \left[\frac{1}{n'^2} - \frac{1}{n^2}\right]$ where the group of constants before the brackets is the Rydberg constant found decades before. a) Use the front cover of your textbook or the internet to find each constant to 5 significant figures and then calculate the Rydberg constant to 5 significant figures. b) Determine the wavelength (in nm) of the transition from n = 4 to 3 using this constant. 6.) Determine the deBroglie wavelength of an electron traveling 2.2 million m/s. In what situation might the wave characteristics of this electron be "noticeable"? 7.) How many neutrons are in the most abundant Isotope of Gold? (Appendix B should provide information to solve this problem and the next problems) 8.) A mineral sample contains some radioactive Polonium-210 which decays by the alpha mode. a) What is the daughter (product) isotope of this decay? b) Is the daughter radioactive or stable? 9.) A sample of radioactive Silicon-31 is being monitored in a laboratory. a) What type of radiation is being emitted from the sample? b) What is the daughter isotope of the radioactive decay? c) Is the daughter isotope stable? d) What is the mass difference (in u) of the parent and the daughter isotope? e) How much energy do the decay products possess? f) If the level of radiation near the sample is 4 times above the "safe level", how long should the lab workers stay clear of the sample?
