Common Values for AS Physics?

[Zenzenzen]

After going through a bunch of physics paper 2s, I've seen a lot of those problems where you have to give an approximate value of things, such as the mass of an apple or the speed of sound in air.

Could someone post a list of the common values?

 

[intel1993]

yea plz sumone was plz post the common asked vaslues..............

 

[workinghard]

i wx thinkin of posting dem
wait till 2nite
if someone doesnt post dem earlier i ll do it!!!!

 

[mrpaudel]

mass of apple is 200g and speed of sound in air is 332m/s..

 

[Zenzenzen]

mass of apple is 200g and speed of sound in air is 332m/s..

Those were just an example, the rest of them would be preferable

 

[princesszahra]

mass of apple
mass of earth
mass of pencil
radius of earth
spped of light in air and vaccum
mass of ruler
mass of a ping pong ball
thickness of a paper

 

[workinghard]

1. mass of an apple: 50 – 500g
2. no of joules of energy in 1kWh = 3 – 4 J
3. wavelength of red light in a vacuum = 6 – 8 (x 107) m
4. pressure due to depth of 10m of water = (5x 104) - (5 x 105) Pa
5. speed of sound in air = 100 – 900 m/s
6. density of air at rtp = 0.5 – 1.5 kg/m3
7. mass of a protractor = 5 – 50g
8. volume in cm3 of head of an adult person = 2 – 9 (x 10-3)
9. frequency of audible sound = 20Hz – 20 kHz
10. wavelength in nm of UV = 10 – 400nm
11. mass of a plastic 30cm ruler = 10 – 100g
12. density of air at atm = 0.1 – 10 kg/m3
13. thickness of a sheet of paper = 0.05 – 0.15mm
14. time for sound 2 travel 100m in air = 0.25 – 0.5s
15. weight of 1000cm3 of water = 8 – 12 N
16. mass of an orange = 100 – 150g
17. mass of an adult human = 50 – 100 kg
18. height of a room in a house = 2 – 3m
19. diameter of a pencil = .5 – 1cm
20. volume of a small bean = 0.5cm3
21. volume of a human head = 4 x 10-3m3
22. the speed of a jumbo jet = 220m/s
23. the temperature of a human body = 310K
24. dis. of earth to the sun = 1.5 x 1011m
25. length of a car = 4m
26. diameter of a hair = 5 x 10-4m
27. diameter of an atom = 3 x 10-10m
28. diameter of a nucleus = 6 x 10-15m
29. typical car speed = 22m/s
30. walking speed = 1.5m/s
31. snail’s speed = .001m/s
32. earth around sun speed = 30000m/s
33. acceleration of family car = 2m/s2
34. acc of freefall on moon = 2m/s2
35. energy released from 100kg of coal = 1010J
36. beat of heart energy = 1J
37. burning of a match energy = 1000J
38. sound of speech on ear for 1sec = .001J

These are the values I came up with in past papers n from da book international as and Alevel physics
There were more but these are the most reasonable ones!
Hope this helps…
Let me know!!!

@workinghard
thanks so much! though the list looks pretty scary ahah

 

[Hateexams93]

i think its insane ..why would they ask us this kind of questions ? wtf , how i'm suppose to know all of this

 

[workinghard]

i didnt sy u need 2 no al da values but look at 1st 15 or 16 n den loook down again u ll find dat some of dem r repeated n dat dey hv come in xams
so dey r insane .... not dese values
rmbr wat u can n den cross ur fingers n pray dat if it comes its dese..
@zenzenzen no problemo!

 

[Feelguud77]

You go through the first few and your like, hold on, i got this, and then its just .................. -__________________-'

 

[Mssamgirl15]

I know right? Why the hell do we need to know stuff like this. Omg. It's insane. God help us.

 

[Feelguud77]

The only ones commonly asked in the papers are the thickness of paper one, wavelengths, frequencies, volume of human head, mass of apple, protractor, scale, speed of sound, volume of air in a room!
*smiles, looks back*.....O.O thats a whole lotta approximations!

 

[smj]

THANKS A LOT !! :Bravo: :good:
BY THE WAY WHAT IS BEAT OF HEAT ENERGY?
SOUNDS LIKE A BAND NAME!!

 

[Feelguud77]

Dude it's a typo..........It's beat of "heaRt" energy -_______-'

 

[workinghard]

hahahahha
wild imagination
if i evr released a band ll make sur i consider dis name
n yeah feelgud is rite it is da energy consumed in 1 heart beat
