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. Unscrew these, and then pull open the hard back slightly to determine if the hardback needs to be slid up or down to be removed.
Making the world better, one answer at a time. If you don't have the special tools, then you first have to remove the big nut on the back of the hub after you've removed the wheel and brake drum of course. Put the nut 3/4 of the way back onto the hub threads.You can tap on that to move the hub out of the bearing (careful not to damage threads).o to the outside and behind the lug nut bolts you'll have more room to see the C clip or retaining ring. I pried out an end of the ring and with a couple of screw drivers worked my way around to remove that ring. From the back side you can use a pipe as I did and pound out the bad bearing.
