Answer:
the extension would be less the new extension might be 3 cm
Explanation:
Answer:
Explanation: Having two separate pathways of reaction and learning from pain is crucial to our survival. ... Therefore, humans tend to avoid objects or events that would cause them pain or harm; thus, adding this to their survival advantages.
Answer: A scalar quantity has magnitude but no particular direction and a vector quantity has magnitude and acts in a particular direction.
Explanation:
A. The average kinetic energy of their particles is the same.
Explanation:
The temperature of an object is proportional to the average kinetic energy of its particles, following the relationship:
where
is the average kinetic energy of the particles
k is the Boltzmann constant
T is the absolute temperature
From this relationship, therefore, we see that the average kinetic energy of the particles in a substance depends only on its temperature: therefore, since the two pieces of iron have same temperature, they also have same average kinetic energy.
The 3003 aluminum alloy is made up of 1.25% Magnesium and 0.1% Copper. This combination is designed to increase the strength of the material over other types of alloys such as those of the 1000 series. This alloy provides a medium strength and can be educated by cold work.
The alloy is not heat treatable and generally has good formability, corrosion resistance and weldability.
However, being a material that hardens by cold work, welding a 3003 Aluminum structure will cause the body to undergo recrystallization which will generate a loss in the 'resistance' of the material and the force capable of withstanding. If this aluminum will be used for structural purposes, it should not be welded. It would be better to perform the structure with a 6061 aluminum, which has similar characteristics and is not so affected by welding.
