Answer:
Barometric pressure is 942.3 cm of column of water.
Explanation:
We can measure barometric pressure by measuring the height h of a column of fluid (this column of fluid exerts the same pressure as the column of air of which we are measuring pressure) using the following formula:
Where ρ is the density of the fluid used and g the acceleration of gravity.
Knowing that both the column of mercury (to match units, we know that 698 mmHg are the same as 69.8 cmHg) and the column of water are representing the same pressure, we can match expressions and find h for the column of water:
Answer: λ = 635 ~6.36 × 10^ −7 m
Explanation:
The volume is the space it takes up, which would be the same. The mass is measured as the weight, and the steel ball would be significantly heavier. Density is mass/volume, and if the steel has a larger mass, it will therefore have a higher density.
