What is the capacitance of this capacitor : A capacitor can be made from two sheets of aluminium foil separated by a sheet of waxed paper. If the sheets of aluminium are 0.37 m by 0.33 m and the waxed paper, of slightly larger dimensions, is of thickness 0.040 mm and dielectric constant? = 2.5..

Which can not be explained by first quantized string theory : In the strong coupling limit of kind IIA and heterotic E8 string theory, we get 11 dimensional M-theory in which we have no strings. Instead, we have M2 brines. Are there any other backgrounds in string theory which can't be explained by first quanti..

Consistent by what is typical of static electricity : Common transparent tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force can be great enough to support the top piece's weight.

A pressure measure at the top of an oil well : A pressure measure at the top of an oil well 18,000 ft deep registers 2,000 psig. The bottom 4,000-ft portion of the well is filled with oil (\rho = 43.68 lbm/ft3). The remainder of the well is filled with natural gas (T= 60 °F, compressibility facto..

Obtains negative charge and other get positive charge : It is always told as a fact without explaining the reason. Why do two objects get charged with rubbing? Why one object obtains negative charge and other get positive charge?

What is the net charge on the shell : A charged particle is held at the center of a spherical shell. The figure gives the magnitude E of the electric field versus radial distance r. The scale of the vertical axis is set with Es = 8.00×107 N/C. Approximately what is the net charge on the ..

What should be the linear mass density of the cord : In the figure below, a cord is attached to an oscillator and wrapped around a light pulley where it is attached to a block with a mass, m = 4.0 kg. The length of the cord among point P and the pulley is L = 1.5 m. When the vibrator is set to a freque..

Concave mirror and converging lens : Concave mirror and Converging lens. f=2cm, h_o = 1 cm, and d_o = 1. Complete ray tracing (for 3 rays), compute d_i, m, and h_i. Is the image virtual or real, invert or upright?

Discover the net work done on the gas and v min : An ideal gas with =1.4 occupies 3.0L at 300 K and 100kPa pressure and is compressed adiabatically until its volume is 2.0 L. It's then cooled at constant pressure until it reaches 300 K, then allowed to expand is thermally back to state A.
