Answer 1

My dear friend please thanks my all answers

Answer 2

Answer:

Height of the hill = 720m

Explanation:

• Ascension causes a linear drop in atmospheric pressure.

At sea level, the air pressure is 76 cm Hg as we can see that also here in this question.

• There is a 120m gain for every 10mm which is equals to 1cm drop.
• So, according to this, at 70cm of Hg the height will be = 76−70=6×120=720m
• Therefore the height of the hill where the barometer reads 70cm Hg is 720m.
