The inductance of a solenoid is defined to be l = î¦b/i, where î¦b is the total magnetic flux passing through the solenoid due to its own b field when a current i flows through it. show that the inductance of a solenoid is equal to l = âµon 2 la, where n is the number of turns per length, l the length, and a the cross sectional area of the solenoid. [5 marks] (2b) a 2000-turn solenoid made of aluminum wire with radius 0.370 mm has length 1.50 m and diameter 5.00 cm. show that the total resistance of the wire making up the solenoid is 20.1 â¦. [5 marks] (2c) this soleoid is connected to a 40.0 v emf through a switch. find the time constant of the resulting rl circuit, ïrl = l/r. [5 marks] (2d) find the current flowing through the solenoid when the switch is just closed, and the magnetic field in the solenoid a long time after the switch is closed. [5 marks] (2e) sketch the magnetic field inside the solenoid as a function of time after the switch is closed.

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
