A 100 nC charge is placed at the origin. A -50 nC charge is placed at x= 5 cm and a 200 nC is placed at x= -10 cm.
b. What is the net electrostatic force acting on 200nC charge?
- How do you invoke a function with named arguments? Illustrate with an example.
- Can you split a function invocation into multiple lines?
1. A voltage of 12 V is placed on a capacitor with C = 85 pF. (a) What is the charge on the capacitor? (b) How much energy is stored in the capacitor?
2. In open-heart surgery, a much smaller amount of energy will defibrillate the heart. (a) What voltage is applied to the 7 F capacitor of a heart defibrillator that stores 60.0 J of energy? (b) Find the amount of stored charge.
3. Calculate the energy stored in a 5 μF capacitor charged to 30 V.
3. A series combination of two uncharged capacitors are connected to a 15 V battery, 300 μJ of energy is drawn from the battery. If one of the capacitors has a capacitance of 5.0 pF, what is the capacitance of the other?
The number of atoms of chlorine present in 5.85g of Nacl is ?( Na =23 Cl=35.5)(Avogadro's number=6.02*10
- Three capacitors with individual capacitances of 2 μF, 5 μF, and 10 μ respectively are connected in series with a 12V battery. What are the total capacitance and total charge in the network?
- Same capacitors in number 1 connected in a parallel. If the combined charge in the network is 50 μC, what are the total voltage and total capacitance in the network?
(H3O+) = 1.9x10%-3
A flywheel has a moment of inertia of 4.8 kg-m2 . What constant force is required to increase its
frequency from 3 rev/s to 6 rev/s in 7 revolutions?
1. Add code to the HTML file to reference the script.js file using best practices. Other than this, do not modify either the HTML or CSS file. 2. In the script.js file set strict mode for JavaScript. 3. Create a new h3 element with your name in it and insert it before the first paragraph. 4. In the footer, add a cite element with the text "Information and photos from Wikipedia" where "Wikipedia" is a link to the page "https://en.wikipedia.org/wiki/Bumblebee". 5. console.log the number of paragraphs with some descriptive text (open the browser console to see the output). 6. Add the class "special" to the second h2 element. 7. Select all the figcaptions and make the font italic. (This will require a for loop.) 8. Once complete, use Zip to compress the whole folder (including all files) and submit the zip file.
1. Why is the word capacitance sometimes called a “misnomer”?
2. We sayu that power is “dissipated” in a resistor. To dissipate is to use, or to waste, or to squander. What is “used” when charge flows through a resistor?
3. When demand for electric power is high, power companies sometimes reduce the voltage, thereby producing a “btrown –out”. What is being saved?
