Er for this question, you can't really explain it over XPC..
Thing is you have to first solve the whole question , which requires drawing lines and measuring angles..
But basically for that part they're asking , if the mirror is moved at an angle of theta (which is 10 degrees, it's given in the question.. they ask you to reflect it at an angle of 10 degrees) will the reflected ray move twice as much, so 20 degrees. It all depends on what you get for part (iv).
Yea i get that but it says that the load is submerged in water ? is it related to water's pressure acting on the load?All right so basically there asking, if you use a longer piece of metal with the same mass , would the extension be the same?
Obviously not, it would be greater.
The next part asks if the density would be the same, and since according to the formula they have provided if E2 increases, so does your density x)
Hope you got it!

ohno i mean from a diagram give XD
its O/N 8 1dWhat was the question again?
i kinda got it . thanks bro

Alright thxSorry, didn't know how to explain that , but your welcome :z
I don't think so, if it were related to water pressure then the extension would be less as it ISN'T completley submerged..
Look at your answers for the previous load, before it is submerged you get 3.1cm, after it is submerged you get 2.4.
There's a decrease in it's extension for being FULLY submerged in water, since the taller load wasn't fully submerged you can conclude it's extension would be greater. That's how I'd answer it x)
its O/N 8 1d
lol yes it isThat is quite a tricky question....
yesnotes 4m smwr in XPC
thank sweetiepie
lol yes it is
its O/N 8 1d
which paper?That is quite a tricky question....
haha YES THANKYUH VERY MUCHBut you got why the answer is that right? RIGHT?!? XD
