current causes upward force on one side of coil and downward dorce on the other side. state direction that coil will rotate. commutator switches current direction.

why are electrons of small wavelength used to investigate nuclear structure?
wave length needs to be smaller than nuclei.
2 of 5
why is the p.d used in a cyclotron alternating?
protons are accelerated between the dees every half rotation.
3 of 5
Investigating conservation of momentum with Newton's cradle?
measure velocity on impact using light gates/data logger etc. mention mv and determine wether momentum is conserved.

what happens after collision in Newton's cradle?
Ke --> sound/ internal energy/ Ke of middle balls. Balls stop when all energy is transferred to these forms.
