Graduate The radius of an electron orbit in helium
hi i am a grade 12 student taking physics 30 (grd 12 level in Alberta Canada) can anyone give me e/m? the charge to mass ratio? today is april 25th and on the 27th i will be going to the university of calgary with my class to do the university labs one of them is charge to mass ratio of the...- sezw

COnversative Forces and Change in Kinetic Energy
Ff as i know it is equal to Fn * \mu \mu= to the kinetic force of friction. NOTE: there are 2 types of friction static and kinetic static is just simply what the friction force is when the object is at rest kinetic friction is what most people find because it is what is most commonly used and...- sezw

COnversative Forces and Change in Kinetic Energy
Ep=Ek Ep=mgh (mass*gravity*height) Ek=1/2mV2 V is velocity at that point you do not need to find final velocity you must manipulate the equations mgh=1/2*mv2 = mgh=1/2* m v2 m cancels out you just need to manipulate the equation and you can find anything- sezw

Solving Tensions & Weights Homework Problem
instead of making things complicated using T[b][c] why don't u just name them T1.T2,T3? easier that way so u don't confuse them- sezw

Block and spring collision - work
ok first what you got to do is find the net force the force applied is what is used to move the object but you must think of it as a vector first force applied is positive whilst ff is negative to find the force of friction you must find the normal force which is easy because it is on a flat...- sezw
