What direction was the arrow supposed to be on the motor effect question? The current was going from right to left and the magnetic field was north closest to us and south further away. This divided my friendship group but I put down...
For the six marker i put Most of the mass of the atoms is concentrated in the centre The protons which have positive charge and the neutrons which are neutral are in the nucleus The protons and neutrons are both heavy and have a mass of one The electrons have a negative charge and they move around the nucleus The radius of the nucleus is much smaller than the the radius of the atom The electrons have no mass The sum of protons and neutron make the relative mass
Yeah haha thats what I got too. What did you lot put about the scientists and why they developed a new atom or something
Because the evidence didn't match up, therefore they prediction was required, also the atom didn't have electrons inside as it went throught the gold foil. i think its wrong lol
B I think? What did you put for the change in focal length for the 60 year old? P3
Was that the graph one on p3? Thought it was for a 90 year old? What length did you use for the focal length for working out the power? Did you convert the units?
