Two different laser pulses from a Nd:YAG laser are used to irradiate living liver tissue: a 100 mJ pulse at a pulse duration of 1 ms and a 100pJ pulse at a pulse duration of 1 ps. Both laser pulses have an average power of 100 W and are focused to a spot of 1 mm in diameter. How will the tissue react in either case. g

Which is the best predictor of the radioactive nature of an isotope? o the proton-to-electron ratio the neutron-to-proton ratio o the neutron-to-electron ratio the electron-to-proton ratio

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
