    This was the one question I missed out on the exam but ethical implications are to do with people so you could probably say something to do with people being paid hardly Amy money in order to generate electricity ...forced labour maybe erm taking advantage of poorer people using them something along those lines
    People shouldn't be able to use other(poorer people's land) in order to generate electicitry maybe? Along as you mention people and how much they get paid something like people may be paid little money in order for companies to generate electricity to sell?
    And
    The size of the red-shift is not the same for all galaxies.
    What information can scientists find out about a galaxy when they measure the size of
    the red-shift the galaxy produces?

    Further away galaxies show a greater red shift than closer ones meaning that the further away galaxies are moving faster away from the earth than nearer ones

    THANK YOU!
    A few more sorry...
    Electricity is distributed from power stations to consumers along the National Grid.
    The voltage across the overhead cables of the National Grid needs to be much higher
    than the output voltage from the power station generators.
    Explain why.

    I'll join that thanks & last one...
    According to kinetic theory, all matter is made up of small particles. The particles are
    constantly moving.
    Diagram 1 shows how the particles may be arranged in a solid.

    7 (a) One kilogram of a gas has a much larger volume than one kilogram of a solid.
    Use kinetic theory to explain why.

    Particles in a solid vibrate around fixed positions and are very close to each other whereas particles in a gas move around rapidly. In a gas the binds between the particles are very weak so it can fill up any space whereas in a solid the binds between the particles are very strong so its volume is fixed.

    i must admit I completely ****ed up on this question as I wrote something out then crossed it out and then I looked at the clock and realised I hadmlikema minute left so I just gave up and closed my paper I felt like such a failure afterwards because I knew the answer but the pressure just got to me!

    Yeah but you still got A* so don't kill yourself over it

    THANK YOU SOOOOOOOOOOOOOOOOOOOOOOOOOOO MUCH!!

    . The reason it's higher would be that it decreases the current which therefore reduces energy losses in the cables which therefore improves the efficient of the whole distribution system !

    yeh I got 90 which is exactly on the grade boundary I would have preferred it to have not been that close! But your right I shouldn't be too hard on myself
