A neutron in a reactor makes an elastic head on collision with the nucleus of an atom initially at rest. Assume: The mass of the atomic nucleus is
about 14.1 the mass of the neutron.
What fraction of the neutron’s kinetic energy is transferred to the atomic nucleus?

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.
