Question was 1.5v battery is replaced with one with significant internal resistance. explain why the value on the voltmemter at A and B doesnt change
No basically the voltage in parallel is the same therefore the potential difference between the two sides will always be 0 as the volts are equal in parallel. Even if it is replaced by a battery with significant internal resistance the difference in volts will still equal 0, because in parallel the voltage is the same

I guessed that one and just put it'll always be zero think I'll get a mark? That was the only question I was unsure on
I put A and D, as an elevator wire cannot stretch. And D because a bungee wire cannot plastically deform, and must stretch easily
I put A for the lift too, but thinking about it I don't think you could use a brittle material. Theres a reason why the cables aren't made from ceramic...

Pretty sure it was B for lift and C for Bungee.
A is too brittle, will snap the second someone steps in lift, needs to strain a little to accoint for weight, but not to much.
C for Bungee as it strains and won't snap easily. Also wont strain so much thay the person hits the ground, which is what would happend with D
