please answer all questions, thank you! (c) If ε-115 V, find the required resistance R (in Ω). 5. (12pts) Two parallel wires separated by 1.m carry currents. One 2 A going froght; the other wire is short (with length of 20 cm), with current of 2 A going from right to left. See schematic below: (a) What is the direction of B field at point P 7 You can directly draw it on the schematic. (b) Find the magnitude of...
13-4 Consider the two circuits shown in Figure 13-5. All currents lie in the same plane. C' is infinitely long. The sides of the rectangle of length b are parallel to C'. Find the total force on C. Is it attractive or repulsive? Figure 13-5. The circuits of Exercise 13-4.
(a) d d A B C (b) d' d' А B с Consider three identical atoms (A, B, C) which are equally separated with a large interatomic distance d as shown in FIG. 2 (a). In this case, each atom has an electronic state, 04), TUB), c), each of which is well-localized at atom A, B and C, repectively (that is, there is no tunneling between different states). Assume that these three states have the same energy E.. Now, suppose...
2. Consider a simplified model of a triply ionized beryllium-9 atom (Be): four protons plus five neutrons in the atom's nucleus, "orbited" by just one electron at a constant distance of 5.75 × 10-12 m. (Note: This is not the actual distance, but it is the correct order-of-magnitude.) 6 pts.) You can solve (a) & (b) in either order. Label your work clearly: a. What is the strength (magnitude) of the attractive electric force between the nucleus and the electron?...
Orthogonal projections. In class we showed that if V is a finite-dimensional inner product space and U-V s a subspace, then U㊥ U↓-V, (U 1-U, and Pb is well-defined Inspecting the proofs, convince yourself that all that was needed was for U to be finite- dimensional. (In fact, your book does it this way). Then answer the following questions (a) Let V be an inner product space. Prove that for any u V. if u 0, we have proj, Pspan(v)...

(c) Use above result to evaluate JeFdr, where C is a smooth curve that begin at the point (2, 1) and ends at (0, 3). (cost, sint) from -2 to t = 줄 particle that moves along the curve. (Write the value of work done without evaluating d) Find the work...
CHEMISTRY 171: PROBLEM SET #1 (9/27/19) DUE: Friday, October 4, 2019 Give the valence shell configuration for: a) Kr. Xe and Rn; b) Br. I and At; c) Se?, Te? Po?:) Mna: e) FI (Flerovium), f) Gd 1. 2. The following are several electronic configurations that may be correct for the nitrogen atom (Z - 7). Arrows represent electrons whose direction indicates the value of the spin quantum numbers. The three circles for the p orbitals indicate the possible values...
need to use the appropriate appendlx table or r this question. Find the t value(o) for each of the following cases. (Round your answers to three decimal places.) (a) upper tall area of 0.025 with 18 degrees of freedom (b) lower tall area of o.0s with 54 degrees of freedom (c) upper tail area of 0.01 with 30 degrees of freedom where 90% of the area falls between these two t values with 29 degrees of freedom and both t...
Problem 4. Radiation from the black hole accretion disk.] In this problem you will find the temperature of an accretion disk surrounding the black hole, and the wavelength of maximal radiation from the disk. Note that the calculation is super-simplified - if you take more advanced astronomy courses, you will do the same calculation more carefully. In this problem 'BH' means black hole. We will consider the BH of mass equal to twenty solar masses MBH = 20 MSun. (a)...
Help with Part C. Please show all your work. I have already tried d=V/E= 7/[(2.9x10^-9)/2(8.85x10^-12) A very large sheet of insulating material has had an excess of electrons placed on it to yield a surface charge density of -4.00 nC/m2. (a) As the distance from the sheet increases, does the potential increase or decrease? (e) increase O decrease Can you explain why without any calculations? The electric field points in the direction of increasing potential while pointing away from negative...
