AS Edexcel Physics answering & explaining Unit 1 Jan 2021 by: Dr. Ahmad Al Faris

for number 5, C is the correct answer, for a material the young modulus, breaking stress, density is independent of dimensions so they're going to be constant if the material used is same. The stiffness is going to vary with the dimension, so think of it in an easier way, if you take 2cm of a wire and another wire of the same material, same cross sectional area, just of a longer length for example 10 cm, which one will be more easier to bend? the 10cm one right? it's because the stiffness is less in the wire with a greater length. The more flexible a material is, the lesser the stiffness. hope it helps :)
