Answer:
work - unchanged
plane-tilted
constant- A surface
inclined- Effort exerted over a distance
Answer:
Well, electrons can be converted into a atomic number so if SE atomic number is 34 that means it has 34 electrons. AI has a atomic number of 13 meaning it has 13 electrons. So the difference is that SE has more electrons then AI.
Answer:
0.488atm = Pressure Kr
Explanation:
The total pressure in a mixture of gases could be defined as the sum of the partial pressures of a mixture. For the mixture of gases in the problem:
Total pressure = Pressure He + Pressure Ar + Pressure Ne + Pressure Xe + Pressure Kr
Converting the total pressure to atm:
1252.5mm Hg * (1atm / 760 mmHg) = 1.648 atm
Replacing:
1.648atm = 0.32atm + 0.21atm + 0.44atm + 0.19atm + Pressure Kr
<h3>0.488atm = Pressure Kr</h3>
