When installing surface mounted cable the best method of ensuring that it is kept straight is by?
When installing surface mounted cable the best method of ensuring that it is kept straight is by using more fasteners that is required by the electrical code. Another way is to install it into a conduit chase. The conduit can be fastened to the building using a level to keep it straight. The cable can then be pulled into the conduit.
How far apart should straps be place on electrical metallic tubing conduit?
Assuming your local jurisdiction adopts the NEC as code, EMT must be fastened within 3 feet of each termination point (box, cabinet, conduit body, etc.) and every 10 feet of conduit run. Where the (horizontal run) EMT passes through a hole in a framing member is allowed to count as a support in lieu of a strap. You can place fasteners closer if you want, but not further apart. There are two exceptions. #1 You can increase distance "within 3 feet of a termination" to 5 feet where structural members do not readily permit fastening within 3 feet. #2 For concealed work in finished buildings or prefinished wall panels where such securing is impractical, unbroken lengths (without couplings) of EMT shall be permitted to be fished. Reference 2005 NFPA 70 (NEC) 358.30(A)(B) Of course if you do not live in the US, or if your local municipality has adopted a different code or adopted the NEC with ammendments, your local law could be different. Check with the local building department to be sure.
How far are electrical services required to be from windows on a residential home in USA?
In the USA the National Electrical Code prohibits the "point of attachment" of an overhead electric service to be within 36 inches of an openable window, doorway, or porch... in other words they do not want a person to be able to reach out of a building opening and be able to touch exposed live power wires. I believe this rule applies to all buildings not just residential. The "point of attachment" is the area near the top of the building's electrical conduit where the building wires are spliced to the utility company wires. This is the only area where there should be exposed power wires. There is no distance limitation from windows and doors for the remainder of the electrical service that has no exposed power wires, such as the conduits, meters, panels

What generates the high temperatures within the sun?
Nuclear fusion.
Can roaches survive a nuclear blast?
Yes if they are sheltered from the initial extreme temperatures which would toast them. The remaining effects due to radiation are within the roach (species) toleration although individual roaches may die. That's how evolution works.

If you have a motor that must remain adaptable to several sizes of belts what is the maximum length of flexible metal conduit you can use before the conduit requires fastening?
Adding an extra length of shaft on the existing shaft to take extra pulleys will put an extra load on the bearings supporting the shaft. In the long term this would shorten the life of the bearings. The makers might be able to supply more information like the side-load specification for the bearings. If in doubt support the outer end of the shaft.
