Derive the formula for the electric field e to accelerate the charged particle to a fraction f of the speed of light c. express e in terms of m, q, d, f, c and v0. – (a) using the coulomb force and kinematic equations. (8 points) – (b) using the work-kinetic energy theorem. ( 8 points) – (c) using the formula above, evaluate the strength of the electric field e to accelerate an electron from 0.1% of the speed of light to 90% of the speed of light. you need to look up the relevant constants, such as mass of the electron, charge of the electron and the speed of light.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
