Calculate the wetting angle for a solid nucleus attached to a mold wall, where the solid-liquid surface energy is 0.177, the solid-mold surface energy is 0.110, and the liquid-mold surface energy is 0.198 J/m2. Given these parameters, how much lower would the heterogeneous nucleation barrier be compared to the homogenous nucleation barrier?
If the average energy released in a fission event is 208 MeV, find the total number of fission events required to operate a 120-W lightbulb for 2.0 h. fission events
In a nuclear medicine scan with 99mTc (t/2 = 6hrs), the signal-to-noise ratioImage size for a 30 min scan was 50: 1 with an injected radioactive dose of1 mCi (3.7x107 decays per second). Assume images startedimmediately after injection. If the scan time was doubled to 60minutes with a starting dose of 1 mCi, what would the SNR value of the image now be?
