1) The electric field inside a conducting wire causes electrons to drift left. This leads to a right flowing conventional current. Answer 2) Conventional current flows into a device at point A and out of the device at point B. The electric potential at point B is larger than the potential at point A Answer 3) The resistance of a wire is measured at an initial temperature. If the experiment was repeated at a higher temperature then...

2. A capacitor with only air between the plates is charged until the electric field strength is 10000 V/m, and it is then disconnected from the charging source. When a slab of solid material is inserted between the plates, the electric field is reduced to 2000 V/m. (a) What is the dielectric constant of the material in the slab? (b) Does the charge on the capacitor plates increase, decrease, or remain the same. If it changes, by what factor? Explain...

An electric field of 8.50 times 10^5 V/m is desired between two parallel plates, each with an area of 35.0 cm^2 separated by 3.00 mm of air. What charge must be on each plate? How does the energy stored on a parallel plate capacitor change if: The potential difference applied between the plates is doubled? The charge on each plate is doubled? The separation between the plates is doubled, as the capacitor remains connected to the same battery? The separation...

I would really appreciate if someone answer these question. Thank you. A charged particle moving in the presence of both an electric and magnetic field moved in a closed path (i.e. a path that begins and ends at the same point). If the energy of the particle at the end of the closed path is 2.0J greater than its energy when it began the path, which of the following statements is correct? a. The magnetic field performed 2.0 J of...

a) What is the total net charge of double-stranded DNA that is 500 basepairs (bp) in length? b) In agarose gel electrophoresis, two parallel and oppositely charged electrodes are situated at opposite ends of the gel. The surrounding solution is a “buffer”, an aqueous salt solution maintained at constant pH. The gel is made in the same buffer, with a small concentration of agarose. Because the concentration of agarose is small , everything between the electrodes can be considered to...
