This is because of the diagram below:
Answer: Partial pressure of nitrogen and xenon are 288mmHg and 548 mmHg respectively.
Explanation:
The partial pressure of a gas is given by Raoult's law, which is:
where,
= partial pressure of substance A
= total pressure
= mole fraction of substance A
We are given:
Mole fraction of a substance is given by:
And,
Mole fraction of nitrogen is given as:
Molar mass of 
= 28 g/mol
Molar mass of 
= g/mol
Putting values in above equation, we get:
To calculate the mole fraction of xenon, we use the equation:
Thus partial pressure of nitrogen and xenon are 288mmHg and 548 mmHg respectively.
Altitude is the height of something or the point of sea level or ground level.

Answer:
option D is correct
Explanation:
It is important to note that equipotential lines are always perpendicular to electric field lines. No work is required to move a charge along an equipotential, since ΔV = 0. Thus the work is :
W = −ΔPE = −qΔV = 0.
Work is zero if force is perpendicular to motion. Force is in the same direction as E, so that motion along an equipotential must be perpendicular to E. More precisely, work is related to the electric field by:
W = Fd cos θ = qEd cos θ = 0.
- The change in kinetic energy Δ K.E by conservation should be:
Δ K.E = W
Since, W = 0:
Δ K.E = 0
- If change in kinetic energy is zero it means that charge moves at a constant speed. Hence, option D is correct.
