A) voltage available to each light remains constant regardless of the number of lights that are on
I took the test
Answer:
Because there is too smooth
Volume % = mole %
Molar mass of oxygen = 32kg/kmol
Molar mass of nitrogen = 28 kg/kmol
Density of nitrogen = Density of
oxygen x molar mass of oxygen x molar ratio of air x molar mass of nitrogen
Density of nitrogen = (1.43kgm^-3)(1 kmol O2/32 kg O2)(80 kmol N2/ 20
kmol O2)(28 kg N2/1 kmol O2) = 5.01 kg/m3
C. 7, 5 solar and 2 lunar eclipses or 2 solar and 5 lunar eclipses
