Answer:
Spring constant = YA / L
Explanation:
Let F be the force being applied on cross sectional area A of metal bar due to which an extension of ΔL is obtained in the wire of length L then
stress = F / A
strain = ΔL /L
Young's modulus = ( F / A ) / (ΔL /L)
Y = ( F L / A ΔL )
( F / ΔL ) = ( YA / L )
Spring constant = ( F / ΔL )
Spring constant = YA / L

The National
Fire Protection Association (NFPA) states that the furthest reaches of human
temperature viability is 212°F, well beneath temperatures found in most
noteworthy structure fires that are past the development (early) stage. In the
present fire conditions, temperatures higher than 500°F can be effortlessly gotten
inside three to four minutes. Flashover, which happens at roughly 1,100°F, can
grow well under five minutes.2 If a space isn't legitimate for firefighters,
caught casualties aren't probably going to survive either. Set aside the
opportunity to make it safe and keep your firefighters from going for broke.

casualties were found to have been presented to warm (most at temperatures over
200°F; some were beneath) and mugginess for six to seven minutes (remote from
the fire range).</span>
It won't make much of a difference, but since gravity is dependant of the distance between the 2 masses, the closer you are the more force. So in the bottom of a valley you will weight a little less.
What happens when you put them together is you will make a stronger magnet that will pick up alot of metal
