Would two 50w bulbs flashing alternately for an hour use the same power as one 50w bulb on constantly for an hour?

Probably not. It would depend on several factors. I would expect that the filament resistance is somewhat dependent on temperature. So if you had a longer duty cycle between switching events the filament would cool down more and perhaps have less resistance. Theoretically if you had a temperature controlled resistance and could do perfect switching then you could probably get it to where the power usage was the same.

How many 75 watt bulbs can be placed on track lighting with 20 amp breaker?
Theoretically a 75 watt bulb at 120 volts draws .625 amps. You would add the individual currents to determine maximum amperage. That would be 32 bulbs. However, you would then be right on the edge and breaker would likely trip often. You should de-rate to 80% of the breaker rating or 16 amps in this case. That would be 25 bulbs. You should also check to see if there is a maximum amperage or wattage rating on the track. Twenty Five bulbs will create quite a heat source.

Why is the right turn signal on a 2002 trail blazer flashing fast?
You have one of two issues. The first is one of the front or rear bulbs are burned out. the second is the flasher is bad. I would bet it is the first one. Watch the bulbs that are flashing on the left side, then you will know which bulb is out on the right side.

How often do you have to replace the bulbs on tanning beds and how expensive is it to maintain a tanning bed?
It depends on how often the bulbs are used. Tanning bulbs last a lot longer when they are not constantly on. Tanning beds in general are expensive to maintain. You will have a high electric bill and bulbs are expensive.

Where is the turn signal relais in a Chevrolet Suburban 1995 problem turn signal is constantly on when activated no flashing thanx?
Check the bulbs first. This is usually an indication of a bad bulb. If all the bulbs light, turn on the headlights and check again. The bulb that won't light has no ground connection. With the headlights off, the circuit was completed through the headlight. The turn signal switch might also be bad. But the flasher is good, since it works on the left.
