A scientist wants to do this experiment but modifies it by filling the balloon with 0.66 moles of neon gas, which behaves as an ideal gas. If the balloon initially holds 0.4 L of the gas and expands to 1.7 L after being ...
Explain, in qualitative terms, how Gauss' Law is modified if two point charges were extremely close together, their separation being less than the wavelength of an electron (about 386 femtometers).
For large integers K and N, what fraction of all binary error correcting codes of length N and rate R = K/N are linear codes? [The answer will depend on whether you choose to define the code to be an ordered list of 2 K ...

1. How many intrinsic electrons and holes are there in a thermal de Broglie cube at 300K in Si corresponding to an energy equal to k B T? What is the thermal fluctuation in carrier density In this cube? Can the intrinsic ...
Estimate how many binary low-density parity-check codes have self-orthogonal duals. [Note that we don't expect a huge number, since almost all low-density parity-check codes are ‘good', but a lowdensity parity-check code ...
A 162 g mass is hung on a spring. As a result the spring stretches 19.5 cm. If the object is then pulled an additional 3.0 cm downward and released, what is the period of the resulting oscillation? Give your answer in se ...
