Answer 1

$\it100 + 2000 \div 2 = 100 + 1000 = 1100$

Answer 2

Answer:Formula

P_h= P_0 e^{\frac {-mgh}{kT}}

P_h = pressure at height h

P_0 = sea level pressure

g = acceleration due to gravity

k = Boltzmann's constant (ideal gas constant divided by Avogadro's number)

T = absolute temperature

m = mass of one air molecule
