Why are copper straps ( rather than iron straps or bent over nails used to hold household copper wire lines in place?
Homework Answers
Copper wire straps are more resistant towards corrosion. The iron wire straps used in the household wires are exposed to oxidation readily. They readily form iron oxide. Hence, reducing its lifetime. The copper straps are thus, preferably used for better conductance, least resistance towards corrosion and more longivity.

A roof plate of iron is held down with rifled steel nails. Over the roof blows sharp winds, at 60 m / s. If each nail can handle 0.5 kN of pull force, estimate how many nails are needed per square meter to hold the plate firm.

1. Copper and aluminum, rather than lead, shields are used to protect against beta particle radiation because: Lead does not absorb beta particles Beta particle beams are not energetic Copper and aluminum shields scatter beta particles, as well as absorb them. Copper and aluminum shields produce less Bremsstrahlung radiation
