Thanks a million )why bother about it actually? if you have repeated readings then finding percentage uncertainity is (1/2 of highest reading - lowest readig)/avg reading x 100

rf = (6.4*10^6) + (1.3*10^7) = 1.94*10^7 m
For this you need to know what the R in the formula -GM\R implies. The R is the distance of the object whose potential you are calculating (i.e the object projected) from the centre of the object exerting the gravitational force (i.e Earth)
AOA
Can someone answer my query.... Light is made of photons (packets of energy) right and is Wave also a part of electromagnetic spectrum ... So are all types of waves within the electromagnetic spectrum made of photons ? Or what is exactly an electromagnetic wave . How might electrons , energy or photons be made into a wave .
O'L student.
open http://papers.xtremepapers.com/CIE/...nd AS Level/Physics (9702)/9702_w10_qp_35.pdfSum1 plzzxz tell me whst is cuming in phy paper31
take with you, you wont lose anything, but i think that we have to wear labcoatGuys i need a "HELP" pls
I have practical exam at 3:00 i have a Q do we have to wear a coat for that as chemistry and biology !!!!
electric field is the force per unit postive charge and the potential is the energy given up by a unit charge when it moves from one point to another in the circuita)
State the relation between electric field strength E and potential V.

this is a question in m/j 2007 paper4 .....i dont understand the ms ...te answers says field stregnth = potential gradient .....and the graph given above is of field stregnth againt distance?!
i think you just need to say that when a certain value increases k increases or decreases according to the realtion given....sensible comment relating to the calculated value of K testing i\against criterion specified by candidate what do they mean by CRITERION ?? in P31 O/N2012

C(i): Change in gravitational Potential = Potential at Earth surface(GM/R) - Potential at Altitude(GM/r) where (r=R + Altitude)Need help with A2 Physics
Guyz i need help in the following question frm year 2003 Physics Paper 4 Q1 (c) :%)
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
