Which subotomic particle identifies an atom as that of a particular element? How is this particle related to the aton's atomic number? Asked by Ollie - Wed Oct 31 21:52:02 2007 - - 5 Answers - 0 Comments A. the particle is called the proton. the number of protons present is called the atomic number. Answered by Dr. Eddie - Wed Oct 31 21:56:45 2007 What is the distance travelled by the particle along the table before coming to rest? Q. The ends of a light elastic string of natural lenght 50cm, and elastic constant k=12N/m, are attached to the surface of a large table. A particle is held against the midpoint of the string and released, travellling along the surface of the table. The frictional force between the table and the particle is 0.02N. Asked by jeanpace89 - Mon Jan 8 14:40:29 2007 - - 1 Answers - 0 Comments A. is this all the information you got? it doesnt make sense. What level is this, AS level or higher? If a particle is "held" against a string and then is released, nothing will happen. Is the string being stretched when the particle is released? If so, what direction? And how far? As long as the table is flat there are no forces acting upon the particle and it therefore will not move. check the question again Answered by G to eorge - Tue Jan 9 21:43:52 2007 What is the speed of the charged particle as it enters the region of the magnetic field?
Q. A particle of mass 1.1454X10^-25 kg. and charge of magnitude 4.8 x 10^-19 C is accelerated from rest in the plane of the page through a potential difference of 218 V between two parallel plates. The particle is injected through a hole in the right-hand plate into a region of space containing a uniform magnetic field of magnitude 0.138 T oriented perpendicular to the plane of the page. The particle curves in a semicircular path and strikes a detector. What is the speed of the charged particle as it enters the region of the magnetic field? Asked by beehappinow - Wed Feb 21 02:30:35 2007 - - 1 Answers - 0 Comments A. This is just equating the electric field to the Kinetic Energy (as the particle is just entering the field). q V = 1/2 m v^2 V - Potential v - velocity So we have-: 4.8 x 10^-19 * 218 = 1/2 * 1.1454 x 10^-25 * v^2 v^2 = 1827134625 v = 42744.99533 or v = 4.2744 x 10^4 metres per second If you want to work out what happens to the particle inside the field use-: Force = q v b (sin theta) = m v^2 / r (you are not given an angle so assume sin theta = 90 -: thus = 1 and can be removed) divide by v to give-: q b = m v / r You can now work out the radius of the particles circular motion (as you have the magnetic field strength and the other variables values apart from 'r') Good Luck...
