Question:

Multiple-choice Physics Q! To produce a magnet from a piece of iron. Never alive materials can be dated.?

1. How does one produce a magnet from a piece of non-magnetic iron?a. It is not possible to produce a magnet from a piece of iron.b. All iron is magnetic so the question is moot.c. Magnets are a natural occurence and cannot be changed.d. One aligns a cluster of atoms in a magnetic field by the use of a strong permanent magnet.2. Materials that were never alive can be dated by usinga. uranium-238. b. carbon-14. c. carbon-12.d. cesium-137.3. Which of the following nuclear particles are least difficult to protect oneself against?a. Gamma and alpha particlesb. Gamma and beta particlesc. Beta and alpha particlesd. None of the above are difficult to protect oneself against.

Answer:

2 chamber flow masters dumped
A really loud legal system would be headers, 3in pipes, and the most unrestrictive Flowmaster mufflers on the market.
I have a 95 Z71 with dually's and Continental glass packs that purr when idling but bark like crazy when I open them up. Just leave your stock exhaust Manifolds in place, replace all existing exhaust pipes with 3-inch stainless steel pipes and either Continental or Cherry Bomb mufflers. Guaranteed to catch anyones attention.
(1) D. You can make a magnet from a piece of iron by wrapping a wire around it several times and running a current through it. The wrapped wire is a solenoid, and it produces a magnetic field when there is a current. This magnetic field aligns the cluster of atoms. (2) B. Carbon-14 has a half-life of about 5,700 years. Scientists detect the amount of carbon-14 is present in an object to estimate its date. (3) B. An alpha particle can be stopped with a piece of paper. A beta particle can be stopped with a sheet of aluminum. And large slabs of lead or concrete or any other dense material is used to absorb gamma radiation.
