Capacitors and Inductors

A 760-µF capacitor is connected in series to a 150 V power supply and a 1.5 k? resistor. At t = 800 ms, the switch is flipped such that the capacitor is in series with only the 175-mH inductor.  At the moment the switch is flipped, what is the voltage (potential) across the capacitor? How much charge is on the capacitor? After the switch is flipped, what is the frequency of oscillation? What is the maximum current in the circuit? What is the maximum energy stored in the magnetic field of the inductor?

Energy Source

Pick a source of energy (wind, solar, hydro, coal, natural gas, hydrogen, petroleum, nuclear, fusion, wave, tidal, etc.) and write two pages about it. You should include the following: – brief overview of the science behind turning this resource into usable energy – climate or other environmental impact of this energy source – current usage (how prevalent is this energy source in the US? the world?) You can of course include more than that, but I at least want to see that info. Format: 12 pt font, 1″ margins, single spaced, maximum two pictures (no more than 3.5″ on a side)

Light and Thermal Energy

By watching the video “We are Not Alone”, it is mentioned how the architects control the sunlight flow into the museum . So you are tasked to create a project ( Research and Experiment- Simulation) to compare the energy intake by human body from sunlight and food then relate it to the concept applied in the Louvre Museum..

Real World Application of Physics

In this small project, you are going to identify a “Real World” situation and analyze it using physics. The Real World situation, in this case, would be instrumental sound waves. All you have to do is,  fully describe the scenario, as well as why it matters, to you or to a broader group. Please include books, web pages, and other resources did you use to find the problem and determine why it is important. In words and in equations, how the physics we are learning (simple nothing too extreme)  impacts your scenario. Using multiple steps, explaining how you know what to do, each step of the way. You can use diagrams if need be.

Electric Potential Calculation

can you show working for these  q1: Charge Q1=+19.3 microC and of mass m=16.8 g is released from rest towards the fixed charge Q2=-57.9 microC . Find speed of Q1 at distance d=4.4 cm from Q2. Give answer is m/s. q2: Find work which is required to bring three charges of Q=9.5 microC each from infinity and place them into the corners of a triangle of side d=2.2 cm. Give answer in J. q3: An insulated spherical conductor of radius R1= 14.6 cm carries charge Q1=+10.4 mC. Second spherical conductor of radius R2=25.2 cm carries initial negative charge of Q2=-16.9 mC. At some moment these two spheres were connected with the long connecting wire. What is the charge of the sphere #1 after everything came to equilibrium? Give answer in mC.

Theory of Relativity Discussion

The Theory of Relativity is one of the most famous ideas bantered around popular culture, but what do we really understand about it? How does it apply to everyday life on Earth? For your initial post, find a reference in pop culture to the theory of relativity. Share this example and explain if your source is a good representation of the theory’s concepts..

Scientific Method Research

Conduct your own physical experiment using the scientific method. Research the scientific method and give a 1-2 page written description of each step. You will then document your process with photos and/or video. Results will also be shared by uploading such media (or the links) of your process to the discussion board in this module. Save and submit the media in this exercise along with your 1-2 page written description.
