However the distance has a positive value, while the displacement does not.

I read about this theoretical phenomenon in my A level physics textbook, OCR A Level Physics A 2015: Student book 2 (OCR GCE Science 2015).

I have heard about some particles which can change to photons in a magnetic field such as the Earth's magnetic field. For example the particles axioms are theoretical particles that are produced by stars and supernova and when our sun produces them they are converted into X-ray photons in the...

Is there an assumption of the work done being vector or scalar, as if it is scalar then this may infer that work has been done, while vector may not have a net work done.

Could you place as magnet surrounded by a coil of wire on a tube with the magnet attached to the bottom of a stretchable sheet that the rain would hit and then electricity could be generated. This would only work I imagine in heavy rain where large and frequent oscillations are common, but still...

I believe that they would still be considered as alkali when dissolved as it would result in a solution that had a pH higher than 7, it would be that OH- ions that would cause the alkaline pH which are from that hydroxide in this case.

Ok thank you that helps a lot

Why would it be more energetically favourable?

my understanding of beta radiation is that an up quark in a proton changes to a down quark, forming a neutron and emitting an electron as the result of the change in charge. My questions are, 1. Why does the quark change? 2. How does it change and how does it change charge?

So a programme that I watched on tv was talking about neutron stars and they said that the neutron stars neutrons were formed by protons and electrons combining to make neutrons. I was just wondering, how does this work, in the field of the quarks in the proton and how they are effected by an...

ok I think I understand, just I am not sure what it is that you mean by a 2nd Taylor polynomial.

So to find the x values of the stationary points on the curve: f(x)=x3+3x2 you make f '(x)=0 so: 3x2+6x=0 x=0 or x=-2 Then to find which of these points are maximum or minimum you do f ''(0) and f ''(-2) so: 6(0)+6=6 6(-2)+6=-6 so the maximum has an x value of -2 and the minimum has an x value...

Other than any form of contact with the water I think that a high voltage arc would be the only other option.
