I have to plan an experiment to do in a lab (but i dont actually have to do it) to investigate how the output of a photocell depends on its distance froma point source of IR radiation. I need to find how the procedure would be, how the output of the photocell would be measured, the ranges of distances, the circult diagrams, and safety precautions and well as featured that would ensure reliabilty and accuracy of my results. This isnt my coursework, but a practice planning exercise im so stuck on. any help would be appreciated!!

I recently read that on striking the nucleus perfectly...many new particles like muons,neutrinos,taus etc. are formed....will somone tell how this acceleration is achieved ??

A child sits on one side of a teeter totter of length 8.00 m, a distance of 45.0 cm away from the end of the beam. The child has a mass of 23.7 kg. Her mother has a mass of 48.5 kg. How far away from her end does she have to sit in order for the teeter tooter to be exactly balanced?

I tried using the equation r2 = r1(m1/m2), but that did not work.

Thanks for any help.

In current electricity,one may say that electron flow in a conductor is just like water flow in a river---when water flows from the opposite ends of a ditch,it results in a collision,just like 2 electrons would if they were to move in opposite directions.But you see,water flowing in opposite directions collide or repel because the water has no other space,or volume,to occupy,other than the volume of the river.Had there been any other space,or volume,to occupy,then some of the water would have occupied the extra volume,& the collision would not be so prominent.This is what happens in case of electrons in motion---when 2 electrons,or 2 streams of electrons,flowing in opposite directions meet in a conductor,they have so much of extra space in the wire to occupy(as the volume of all the electrons flowing in the wire is negligible as compared to the volume of the wire), that a collision could easily be prevented.So why does it take place. I may be wrong with my reasoning,but please explain.

In a television set, electrons are accelerated from rest through a potential difference of 17 kV. The electrons then pass through a 0.29 T magnetic field that deflects them to the appropriate spot on the screen. Find the magnitude of the maximum magnetic force that an electron can experience.
