did you do as? unit 1 aqa board
Hi I saw the physics unit 5 thread I currently i have neutral preference to all of the options but wondered what people who did medical physics thought about it and if they suggest doing it? and if anyone give an opinion about choosing the options. (I applied for med and biomed if it will have any effect )
Drop medicine, do a real degree like science or engineering.
Hi!

page 195 for the section 1 + astronomy mark scheme, no unofficial for the other secondary units yet though
Work out the power of the sun as you have the radius (p=Stefans constant*surface area*surface temp^4) x by 70000 then use temp of Daneb worked out in previous part to find surface area of daneb then work back to radius of Daneb. The Stefan constant will cancel, if your alright with this, you can therefore ignore it. Surface area = 4pi r^2
