The amount of meat in prehistoric diets can be determined by measuring the ratio of the isotopes nitrogen-15 to nitrogen-14 in bone from human remains. Carnivores concentrate 15N15N, so this ratio tells archaeologists how much meat was consumed by ancient people. Suppose you use a velocity selector to obtain singly ionized (missing one electron) nitrogen atoms of speed 8.50 km/skm/s and bend them along a semicircle within a uniform magnetic field. The 14N14N atoms travel along a semicircle with a diameter of 32.2 cmcm. The measured masses of these isotopes are 2.32×10−26kg2.32×10−26kg (14N14N) and 2.49×10−26kg2.49×10−26kg (15N15N).
Part A.
Find the separation of the 14N14N and 15N15N isotopes at the detector.
Express your answer with the appropriate units.

When a positron is emitted, it goes only a short distance before coming nearly to rest. It forms a bound state with an electron, called "positronium", which is rather similar to a hydrogen atom. The binding energy of positronium is very small compared to the rest energy of an electron. After a short time the positron and electron annihilate. In the annihilation, the positron and the electron disappear, and all of their rest energy goes into two photons (particles of light) which have zero mass; all their energy is kinetic energy. These high energy photons, called "gamma rays", are emitted at nearly 180° to each other. What energy of gamma ray (in MeV, million electron volts) should each of the detectors be made sensitive to?
