Identify the areas of physics involved in each of the following tests of a lightweight metal alloy proposed for use in sailboat hulls:
a. testing the effects of a collision on the alloy
Would this be relativity since relativity includes particle collisions?
b. testing the effects of extreme heat and cold on the alloy
My answer is thermodynamics dealing with temperature.
c. testing whether the alloy can affect a magnetic compass needle
ummmmm....... electromagnetism? because it says "magnetic"?
Testing the "effects" of collision involves strength testing, which involves forces and deformations. Mechanics.
Effects of heat and cold: Mechanics again, with thermodynamics.
im wondering if me and my boyfriend are getting back together.
Tom has a mass of 28.9 kg, as Tom paddles, a force of 9.9 N acts in a direction due east. In addition, the current of water exerts a force of 3.6 N on Tom in a direction 53o south of east. When these forces begin to act the initial velocity of the Tom is 20 m/s in a direction due east. Find the ydirection displacement of the Tom in 8 s.
