We can certainly draw water into our lungs, even though
our brain screams "Don't do that !".
But our lungs can only separate oxygen out of air, not out of
water. So if there's only water in our lungs, we pass out after
a short time because we're not getting any oxygen.
Reaction: Na + Br → Na⁺Br⁻
Ion formed = Br⁻
As bromine is gaining an electron here, it is "Reduced"
Hope this helps!
Answer:
The answer is below
Explanation:
Distance is a measurement of how far apart two points are. Distance is a scalar quantity, i.e. it has magnitude and no direction.
Total distance traveled = distance traveled north + distance traveled east + distance traveled south
Total distance traveled = 100 + 50 + 60 = 210 meters
Displacement is the shortest distance between the starting and end points.
displacement² = 50² + (100 - 60)²
displacement² = 2500 + 1600
displacement = 64 meters
The displacement of the journey is vector, because displacement is a vector quantity.
Answer:
Explanation:
In that the gas thermometer is a constant volume, it is satisfied that:
How the boiling water is under regular atmospheric pressure, then
Thus
This is the mechanism behind a thermocouple (choice D). The two metals generate a magnetic field between them when the temperature is varied, and this causes a voltage (potential difference) to form between the metals. An electronic meter is calibrated to translate this voltage difference into a temperature value for a user to read.
