Calculate the expected frequency, t_high, and t_low for the 555 timer as configured with external 470 ohm resistors and 1000 μF capacitor. Show the equations and your math. Does the timing seen in your circuit match the predictions of the equations?

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
