Assume that the above neutron fluence is approximately uniform throughout a tissue sphere 5 cm in radius, due to thermalization of a field of intermediate- energy neutrons penetrating the sphere. What is the absorbed dose at the center resulting from thermal-neutron-capture y rays

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

In the first law of thermodynamics, triangle e=q-w, what does q stand for

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
