Alarge 75-kg lighting fixture can be hung from wires of identical size and shape made of aluminum, brass, or copper. the values of young's modulus for these metals are 0.70 × 1011 pa (aluminum), 0.91 × 1011 (brass), and 1.1 × 1011 (copper). which wire would stretch the least distance? a. aluminumb. brassc. copperd. they will all stretch the same distance

C. Copper

Explanation:

F = Force on string

= Intial length of string

A = Area of string

E = Young's modulus of material

Change in length is given by

It can be seen that the change in length is inversely proportional to the Young's modulus of the material.

Here

So, copper will stretch the least.

i was thinking more like reflects green light, just not sure

b would be the answer
