Okay,i'm worried on this question? in the materials one,what was the labelling of X? limit of proportionality? or elastic limit?
i guess it was the limit of proportionality. coz i think the second point bfor ultimate tensile strength is spouse to b elastic limit. lol i guess almost evry bdy mixed up stuff there :barefoot:.

it was that cylinder with metal ball being dropped in
oh yes!!! i ticked the option saying ''smaller size ad greater in mass'' coz greater mass il obviously coz the downward force to increase so it will travel in lesser time plus the smaller in size means lesser surface area ad bcoz of this less drag force wil act. therefore the magnitude of total unbalanced force downward il b greater
