Physics topics Edexcel 2019 higher:
Sources of background radiation,how to find the critical angle,Big bang theory cmbr and red shift(six marker ),how to measure radiation (Geiger muller tube), loads and loads of equations that I don’t even remember ,how are gamma rays and radio waves produced (6 marker),label a light ray diagram of glass to air,centripetal force,speed & velocity,graphs to find calculations,why infrared remote controls don’t work when covered but radio wave remote controls do,half life equation ,tracers,state one idea about the solar system that has changed over time,scenario of trolley going up a hill, and another scenario of clapping distance and how to improve results . That’s all I remember and it’s quite a lot of the paper so I hope that’s useful to anyone ,Good luck!

okay physics: 6 marker on big bang (cmbr and red shift) another 6 marker on how radio waves and gamma rays are produced. a TON of maths- rearranging and graphs. half life question was 17100
U remember anything else my mock is literally on Tuesday get back to me fast please!!!

What do u mean by how radio waves produced I know that how gamma Rays are produced but is radio waves even in the spec I swear its meant to be how beta particles are produced or something?????

Hello, how did you guys find the paper? I found it good but like a couple questions were hard. Feel free to share answers, etc.
can someone please help with this with working preferably

Fe2O3 plus 3Co --> 2Fe plus 3Co2
What mass of carbon monoxide is needed to react with 2.08g of iron oxide?

2Fe plus 3Cl2 --> 2FeCl3
What mass of chlorine reacts with 20.0g of iron to from iron(III) chloride?

2NH3 plus H2O2 --> N2H4 plus 2H2O
Hydrazine (N2H4) is used as a rocket fuel. It can be made by reacting ammonia with hydrogen peroxide. What mass of ammonia is need to make 148g of hydrazine?
