Joan and Dick spent 2 weeks (14 nights) touring four cities on the East Coast: Boston, New York, Philadelphia, and Washington. They paid $240, $450, $170, and $100 per night for lodging in each city, respectively, and their total hotel bill came to $4200. The number of days they spent in New York was the same as the total number of days they spent in Boston and Washington, and the couple spent 3 times as many days in New York as they did in Philadelphia. How many days did Joan and Dick stay in each city? (Let x, y, z, and w denote the numbers of days spent in Boston, New York, Philadelphia, and Washington, D.C., respectively.)

Consider the following synthetic target below, shown in its 3D ball and stick representation. In the diagram, a gray ball indicates a carbon atom, a white ball indicates a hydrogen atom and a red ball indicates an oxygen atom. Assuming the product was made via an aldol condensation, identify the starting material necessary to generate this product. Aldol Condensation

*Please help with MULTISIM SIMULATION section. Please provide thorough explanations. Page 1 provided for reference only. THANK YOU Field Effect Transistors During this lab you will experiment with n-channel and p-channel Field Effect Transistors (FETs), and for this purpose you will be using an MC14007UB CMOS array. Figure 1: MC14007UB pin assignment Figure 2: MC14007UB schematic Voltage-Current Characteristics Figure 3: Circuit for measuring MOSFET's output characteristic Connect the circuit shown in Fig. 3. With VDD at 10 V and V_(G) at 0 V initially, raise VGG until a small drain current (a few microamps) flows. Measure the threshold voltage VGG. Raise VGG to 2 V . Measure ID while lowering VDD in steps of 1 V . Repeat the above step with V_(G) set at 3V,4V, and 5 V . Draw a graph of I_(D) vs. V_(DS) with V_(GS) as a parameter. Having measured several V_(GS),V_(DS), and I_(D) values, find the parameter k_(n)^(')((W)/(L)) Multisim Simulation Select an NMOS transistor of your choice in Multisim. Use a similar circuit as in Figure 2, and follow a similar procedure in Multisim as you did in the lab to find the MOSFET characteristics (the threshold voltage, and the k_(n)^(')(W//L) value). Simulate a common source amplifier using very large coupling and bypassing capacitors. Use an input voltage of your choice (make sure it is not very large) and measure (in the simulation) the gain of the amplifier. Also, calculate the gain using the information you found in part M1 by analyzing the small signal circuit (you also need to find gm, thus the Q point).

Sketch and Explain: If the basketball were dropped from 15 cm below the motion detector, and bounced a few times, how would the potential energy vs. time, kinetic energy vs. time, total energy vs. time graphs look. Try this, and sketch the three graphs below, but don't hit the motion detector with the ball. Is the total energy of the ball still conserved? Sketch: Include units and labels on both axes. Explain the shape of each of the three graphs: **please draw out and explain ******
