Would you be willing to travel to a star 10 light-years away and spend 5 years on the planet orbiting this star before returning home (25 plus years of your life) if you could travel at 99.9% the speed of light both ways? explain, and be sure to include your calculations to defend your reasoning.

What should the power status of a circuit be when measuring resistance with an ohmmeter?

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
