A) If you want to increase the capacitance by changing the shape and size of the capacitor, how would you do that?

B) If you want to increase the capacitance but NOT change the shape and size how could you do it? Explain in some detail why your idea will increase the capacitance.

C) You connect a 4 microfarad capacitor to a 10 volts battery. You then disconnect this capacitor from the battery. You then connect this 4 microfarad capacitor to an uncharged second capacitor. When you measure the voltage across the 4 microfarad capacitor it has dropped to 7.7 Volts. What’s the capacitance of the second capacitor?

Expert Solution

q=cv => yxhob x 10 { =) YO MC qoq Charge will flow Hall 9-20 potential of bottes from first capacitor to to unchanged capacitor due to potential difference Given v = 7.7 wit se ve 9-20 = 7.7 YO-20 = 7.7 Port yo- 3008 = 9.2 Mc finally voltage of both will be some because change will How until they both have some potential. rev=20 c'e 20 a 9.2 c=1-2 MF

1. Radios often utilize a variable capacitor (capacitance is changed by either changing the distance between plates or amount of dielectric between plates) in series with an inductor to tune the circuit to a particular frequency. In a particular shortwave radio, the value of the inductor is \(L=1.09 \mu H .\) What must be the capacitance (in \(\mathrm{pF}\) ) of the circuit so that the radio is tuned to a frequency of \(\mathrm{f}=6.95 \mathrm{MHz}\) ? 2. A conducting coil, with...

You want to see graphically the effect of changing the standard deviation of a Normal distribution. Let μ = 100 for both distributions, but let σ = 10 for one and σ = 16 for the other distribution. Recall that for each distribution the first value should be 3σ below the mean of 100, and the last value should be 3σ above the mean of 100. When MINITAB creates the X values for you, for both distributions this time set...

You are an aspiring biologist and you want to document the size of a sea turtle population over time. Starting with the vital rates, describe the different factors that will directly impact the size of the population over time (3pts). What else could impact a population (directly and indirectly) size over time (list at least 5 things based on what we have chatted about in class) (7pts).

First, I want you to pick something that you have been thinking about changing in you life (maybe a major decision) but have been on the fence in doing it or unsuccessful in getting to it. Something that you are willing to talk about in class that's appropriate. It must be meaningful (Not something like -- I have been thinking about changing the shower curtain). It may be something that you have attempted to change in the past or maybe...

If the size and shape of two objects A & B are the same, but object B has a smaller mass: (a) for which object would the beta factor be larger? Justify your answer. (b) Which object would have a larger terminal velocity? Justify your answer. (c) Using a-b: if you dropped styrofoam ball and a steel ball of the same size/shape off a tall building, which would land land first, discounting air resistance? How about including air resistance? beta=...

1. True or false? If a sample size is large, then the shape of a histogram of the sample will be approximately normal, even if the population distribution is not normal. 2. True or false? If a sample size is large, then the shape of the sampling distribution of the average will be approximately normal, even if the population distribution is not normal. 3. True or false? A sample histogram will have a normal distribution if the sample size is...
