Im really confused I thought I rearranged and moved the y^2 to the other side, I am I missing a really easy point, how could I change it to make it linear

Homework Statement do I use the integrating factor for this question and if I do when i rearrange y^2 to the other side into the form of p(x)y does x become -1 Homework Equations The Attempt at a Solution

I see so I would be using cos24 not cos66

The Earth's magnetic field at a certian location in the uk has a magnitude of 48x10-6T and is directed at 66 degrees below the horizontal. Determine the magnitude of flux of the Earth's magnetic field through a wedding ring of diameter 2.2cm when the ring is held in the horizontal plane. What...

Sorry missed out the most important part ABcos(theata) can't find symbol for that. the question asked you to find magnetic flux I have worked out A and B but I am unsure what it means when it says : the angle is 66 degrees below the horizontal: Thanks

Homework Statement if a questions states that the angle of 66 degrees is below the horizontal is that the angle I put into the equation Homework Equations The Attempt at a Solution

Hi ghostbuster remember the B dot A cross product rule that helped me and the angle is below thw horizontal so work out the angle you need

Equation relating electric field and potential is Ex= -dV(r) dx if it just relies on x then is it just an inverse sketch of the pd graph

Homework Statement Sketch 2 diagrams 1 showing Ex against x and 1 showing Fx against x Homework Equations The Attempt at a Solution I have drawn a graph showing potential difference against x and have been asked to produce a sketch showing Ex and Fx relating to this graph but I am...

Hi Coz I worked out the same as you and I am still not sure how to proceed Have you had any joy yet

Im having a mental block how can I work out gravitatinal force if I haven't been given any masses,

I have worked out the electrostatic force for both sides of the see-saw but I am unsure of how to proceed to get the mass of the block Thanks in advance

Thank you for that hopefully I can get going now

b]1. Homework Statement [/b] A see-saw with a central pivot is made of insulating material. the left hand side supports a conducting sphere of charge Q= 5.0x 10-6 which experiances an electrostatic force from an idetical sphere 10cm below with +Q the right end has anouther conducting sphere of...
