Find the equivalent capacitance in the following figure. What is the total charge? Also find the charge and voltage on 1µF and 8 µF capacitors.    

In a double-slit experiment the distance between slits is 4.1 mm and the slits are 1.0 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 470 nm, and the other due to light of wavelength 640 nm. What is the separation in meters on the screen between the m = 3 bright fringes of the two interference patterns?

The coefficient of linear expansion of steel is 11×10–6 per C°. A steel ball has a volume of exactly 100 cm3 at 0° When heated to 90°C, what is the new volume? 

A coil consists of 200 turns of wire. Each turn is a square of side d =18 cm, and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. If the field changes linearly from 0 to 0.50 T in 0.80 s, what is the magnitude of the induced emf in the coil while the field is changing?

Two equal charges (Q = + 1.00 nC) are situated at the diagonal corners A and B of a square of side 1.0 m. What is the magnitude of the electric field at point D? (C and D are the another diagonal corners).The Coulomb constant is k = 9.0×109 N×m2/C2.
