Aparticle of rest mass m, travelling at speed v in the r-direction, decays into two photons, moving in the positive and negative x-direction relative to the original par- ticle. what are their energies? what are the photon energies and directions if the photons are emitted in the positive and negative y-direction relative to the original particle (i. e., perpendicular to the direction of motion, in the particle's rest frame).

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
