Explain physically how one can use gauss law
(i) Explain physically how one can use Gauss's Law to find the electric field of a long (infinite) charged wire? (ii) Now do the same for a finite charged wire, explain why you can still use Gauss's Law but it's not useful to use in the case.

The number of traffic accidents in a town in 10 randomly chosen rainy days in 2012 is as follows: {4, 0, 6, 5, 2, 1, 2, 0, 4, 3). Use these data to estimate the proportion of rainy days in this town that had 2 or fewer accidents that year.
A 10-kg block is attached to spring A and connected to spring B by a cord and pulley. The block is held in the position shown with both springs unstretched when the support is removed and the block is released with no initial velocity.
Is globalization a form of Western imperialism that may homogenize non-Western values? Why or why not? Can homogenization be avoided or mitigated?
So why don't the electric fields for the infinite line and infinite sheet of charge also fall off in the same way? Hint: As the Gaussian surface gets very far from the source charge, look at what its characteristics depend on.
If the mass flow rate of steam is 50 kg/h, determine the rate at which heat is removed from the steam, in kJ/h. The rate of heat rejection to the cold reservoir, in kJ/h.
The structure of a house is such that it loses heat at a rate of 4825 kJ/h per degree Celcius difference between the indoors and outdoors. A heat pump that requires a power input of 6.2 kW is used to maintain this house at 26 degrees Celsius.
A sphere is placed in a uniform external electric field. Accurately draw the vector field lines for the situation when the sphere is a (i) conductor and (ii) then replaced with a uniformly polarizable dielectric. (iii) Briefly explain how your fie
Steam enters a turbine at 120 bars and 440 0C and expands to 1 bar. At the exit entropy is 0.650 kJ/kg. K, greater than at the inlet. The process is adiabatic and change in kinetic and potential energies may be neglected.
