Chapter 04 Homework 12. Market equilibrium and disequilibrium The following graph shows the monthly demand and supply curves in the market for combs. Use the graph input tool to help you answer the following questions. You will not be graded on any changes you make to this graph. Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly. The equilibrium price in this market is per comb, and the equilibrium quantity is combs per month. Complete the following table by indicating at each price whether there is a shortage or surplus in the market, the amount of that shortage or surplus, and whether this places upward or downward pressure on prices.
Choose the correct vector as a result of applying the rotation matrix to v, shown in the graph to the right. [2-sqrt(3), 1+sqrt(3)] [-4, -2] [-2, 4] Rotation Matrix [-1 0, 0 -1]
Multiple Choice Question A wheel is free to rotate about a line passing perpendicularly through its center. Only one torque is applied to the wheel. From your point of view (looking along the axis of rotation), the torque causes the wheel to rotate faster in the clockwise direction. What is the direction of the torque exerted on the wheel? Vertically downward Away from you Toward you Vertically upward To your left To your right Need help? Review these concept resources.

From your point of view (looking along the axis of rotation), the torque causes the wheel to rotate faster in the counterclockwise direction. Identify the direction of the torque exerted on the wheel. Vertically upward Vertically downward Away from you To your right Toward you To your left Need help? Review these concept resources.
Velma conducted a study with 49 coffee drinkers who add chicory and found the sample mean of the amount of caffeinated coffee they drink to be 14.36 ounces, with a sample standard deviation of 2.46. She wants to test if this is less than the accepted average of 15 ounces. At a significance level of α = 0.04, what is the p-value for this test? Round to 4 decimal places.
Given the following velocity vs. time graph, describe (in words) how you would move to match the motion described by the graph. Use words like faster, slower, toward, away, etc. Assume that a positive velocity is "forward" and a negative velocity is "backward".
Figure 9: Instrumentation amplifier. Consider the circuit in Figure 9, which represents an instrumentation amplifier (A1, A2, A3) with additional functionality (A4, A5). All operational amplifiers are assumed to be ideal. (a) [5 points] Derive the transfer function H1(s) = (V2-V1)/(Vint-Vin). Hint: Set up independent equations that involve Ig, the current through Rg and eliminate Ig. Use your knowledge about ideal operational amplifiers. (b) [5 points] Derive an expression for (V01)/(Vout) of the sub-circuit with A 5 and for (V02)/(Vout) of the sub-circuit with A4. Calculate the transfer function H2(s) = (V02-V01)/(Vout). (c) [4 points] Set up the circuit equations for operational amplifier A3: Find a relationship between VN and VP, then set up circuit equations for V1, Vol, V2, and Vo 2 to derive the transfer function H3(s) = (V02-V0)/(V2-V1).
Duas caixas de massas iguais são puxadas ao longo de um piso áspero pela força F mostrada na figura abaixo. As caixas têm uma aceleração resultante de 2,5 m / s^2 para a direita. Qual das seguintes afirmações compara corretamente as forças que as caixas A e B exercem uma sobre a outra? Escolha 1 resposta: (A) A força exercida na caixa B pela caixa A é maior porque deve ser somada à força F aplicada. (B) As caixas exercem a mesma força, uma sobre a outra, porque este é um par de ação e reação. (c) A força exercida na caixa A pela caixa B é menor porque há apenas uma força atuando na caixa A. (D) A força exercida na caixa A pela caixa B é menor porque a caixa B está puxando apenas metade da massa do sistema.

A 55.0 kilogram (kg) block of metal has an original temperature of 15.0°C and 0.45 J/g°C. What will be the final temperature of this metal if 75500 J of heat energy is absorbed by the metal?
A gas sample has an initial pressure of 547 mm Hg and an initial volume of 0.500 L. What is the pressure (in atm) if we decrease the volume of the sample to 225 mL? Assume the temperature and number of moles remain constant.
