For the solar pannel one, yousee the value was 1000kwh in a year.so wat i did was For one hour you therefore had to divide this by the no. of hours in a year. Then divide this by 3600 to get per second

i thiught that exam was pretty good but i did physics this morning because of a reschedule, before aqa told my school about that question 9 thing to cross out and i spent about 8 mins trying to do that question, just guessed in the end but theyll just ignore it anyway

Did you get 2.7mm then? If so how did you do it?

As their were 2 lines before the 0

For the mass of a fuel decreasing, did people put A- less friction. I simply thought M1 mechanics here.

I was thinking that with the reaction force decreasing but the max acceleration would also increase as this is when the motive power is max and drag is zero i.e. when the car has just started its journey. So since m is lower but F is constant F/m decreases maybe?
