The critical mass of a fissionable material depends upon its nuclear properties (specifically, the nuclear fission cross-section), its density, its shape, its enrichment, its purity, its temperature and its surroundings.
i hope this helps. if it does please mark brainliest.
Well if shes at a beach i would think that the sun is out and because of radiation they're gonna get hot. somebody should probably warn her or she's gonna burn her feet
Answer:
most probably 5120J. or 32000x0.8= 25600J
Explanation:
the 1st machine has 20% efficiency. if we supply 32000 joules to the 1st machine then the work output is 32000x0.2 = 6400 J.
if this output from the 1st machine with an output of 6400J is passed through the second machine with an efficiency of 80% then we get 6400x.80 = 5120J.
Ocean currents are caused by density differences in the water and move water masses through the deep ocean
