Question A point charge q = 3.80 nC is 8.00 cm from a thin, flat, infinite sheet that has a uniform surface charge density. If the total electric field is zero at a point halfway between the point charge and the sheet, what is the surface charge density of the sheet? =

A rectangular coil with 9000 turns that has a resistance of 4.9Ω is coplanar with a long wire which carries a current which depends on time according to I0exp⁡(−t/τ), where I0=3 A and τ=6.3 s. The rectangular loop has a width of W=3.4 cm and length L=4 cm. The near side of the loop is a distance D=3.7 cm from the wire. a)What is the magnetic flux in ONE turn of the coil at t=3.4 s? b)What is the emf in the entire coil at t=3.4 s? For the purposes of entering a sign, let the positive direction for the emf in the loop be in the clockwise direction. c)What is the power dissipated in the entire coil at t=3.4 s? d)What is the total energy dissipated in the entire coil from t=0 to t=3.4 s?

C+ Q1. The Students' Corner Store in a university needs a program to implement its students' discount policy. The program is to prompt the user to enter the purchase total and to indicate whether the purchaser is a student. Students are eligible to receive a 20% discount on all their purchases. The discount calculation, however, must be done before addition of the 5% sales tax. This is done to ensure that the discount is not applied to the sales tax. Here are two sample output files - one for a student purchaser and one for a nonstudent purchaser. Total purchases: $ 122.00 Student's discount (20%2:24.40 Discounted total: 97.60 Sales tax (5%): $ 102.48 Total purchases: $ 24.90 Sales Tax (5%): 1.25 Total: $ 26.15

THANKS A MELON FOR MAKING MY BIRTHDAY SPECIAL! 1. A concrete column 4.30 m high with a cross-sectional dimension of 20 cm x 25 cm is resting on a concrete footing 30 cm thick x 80 cm square. If class "B" concrete is specified, find the quantity of cement, sand, gravel, and water if there are 12 columns of the same size. Use 40 kg / bag cement. Water-cement ratio is 50%. 2. Prepare bill of materials for the masonry works using CHB. Use 40 kg/bag cement - class "B" for concrete and class "C" for mortar and plastering. Take note that only the outer part of the wall will be plastered. 0.35 m. 0.70 m. 1.00 m. 0.50 m. W-2 1.20 m. 3.00 m. 1.20 m. 0.70 m. B В A 2.70 m. 2.10 m.

Shown in the figure below is a capacitor. Each plate has an area of A = 1.4e-02 m2 and has a gap d = 6.6e-04 meters. Att filled with a dielectric of constant K = 3.87. The thickness of the dielectric layer is a = 2.64e-04 meters leaving a free space Empty Capacitor Partly Filled Capacitor Area = A dielectric constant K d Write the FORMULA for the capacitance of the empty capacitor. 1 Determine the capacitance of the empty capacitor Cempty = Farads When you partly fill the capacitor, which of these best describes the new configuration: Parallel Series Both series and parallel Neither series nor parallel e-02 m2 and has a gap d = 6.62-04 meters. At the first moment, the capacitor is empty. At the second moment is it partly ayer is a = 2.64e-04 meters leaving a free space of b = 3.96e-04 meters. dielectric constant Farads - configuration: Determine the formula for the partly filled capacitor Chilled = Determine the value of the partly filled capacitor Chilled = Farads NOTE: Decide whether the partly filled capacitor acts like parallel or series by following the charge: . If the charge splits between the caps, parallel. • If the charge is the same on both caps, series, • The formula for the filled capacitor should use only the distances a and b (NOT d).
