A or B... I mean when lava is poured out to the surface, heat and soilica content may play a role... That's what I think sorry :(
Just because there is more mass in a certain substance doesn’t mean it’s density will change. In this case, water, will not change density simply because there is more of it. I.e the ocean. The bottom of the ocean may have more pressure to it because of the weight of the water above it but if you were to take a cup of it and take it to the surface it wouldn’t sink.
Answer: I’m gonna assume 40 m north
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).
Answer:
Local atmospheric pressure in kPa = 97.932 kPa
Local atmospheric pressure in mm Hg = 734.78 mm Hg
Explanation:
Given:
- = absolute pressure = 46 kPa = 46000 kPa
- = density of air =
- = density of mercury =
- = altitude of the plane = 6400 m
Assume:
- = pressure decrease due to air at height h
- = local atmospheric pressure
As we go up the altitude, the pressure decreases. So, the reading of the pressure will be equal to the decrease in pressure due to height subtracted from the local atmospheric pressure.
Now, conversion of the local atmospheric pressure is quite simple. let us assume that height of H mm of Hg is required to exert a pressure equivalent to the local atmospheric pressure.
Hence, 734.78 mm Hg is the local atmospheric pressure in mm Hg.

Hope this helps!
