Identify the areas of physics involved in each of the following tests of lightweight metal alloy proposed for use in sailboat hulls. a. testing the effects of collision on the alloy b. testing the effects of extreme heat and cold on the alloy c. testing whether the alloy can affect a magnetic compass needle

Explanation:

A - Testing the effects of collision of the alloy : the area of physics involved here is the strength testing which is a part of mechanics.

B - Testing the effect of extreme heat and cold on the alloy : the area of physics involved here is the Thermodynamics which deals with the relationship between all forms of energy.

C - Testing whether the alloy can affect a magnetic compass needle : the area of physics involved here is the magnetic properties of any substance. If the alloy posses magnetic characteristics then the needle of compass will deflect in its presence.
