This question can likely be answered using the formula E=hc/w where w is wavelength, h is Planck's constant, c is the speed of light, and E is energy in Joules. 5 electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent.
Remove the hog-rings as you roll the cover up over the seat. If your seat has a hard back, there will be a series of screws along the bottom that hold the bottom of the hard back to the seat.
