Calculate the minimum kinetic energy of the incident proton that will allow this reaction to occur if the second (target) proton is initially at rest. the rest energy of each kaon is 493.7 mev, and the rest energy of each proton is 938.3 mev. (hint: it is useful here to work in the frame in which the total momentum is zero. note that here the lorentz transformation must be used to relate the velocities in the laboratory frame to those in the zero-total-momentum frame.)

If element x has 99 protons how many electrons does it have

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
