Answer:
1.28 m
Explanation:
Generally, pressure of fluid is given by
where g is acceleration due to gravity, h is the height and 
is the density
Considering that the pressure for mercury is same as for blood only that the height and density of fluid are different then
Since g is constant, then
Making 
the subject of the formula then
Where subscripts m and b denote mercury and blood respectively
Assuming density of blood is 1060 Kg/m3, density of mercury as 13600 Kg/m3 and substituting height of mercury for 0.1 m then
Active transport move molecules from low concentrations to high concentrations.
Answer:
you are going 1 mile per hour depending on how fast
Explanation:
well in my own words, i'd saw the the doppler effect is similar to light because sound has a speed, and light does too.
so my theory is if you go fast enough everything would just become black, or maybe white? idk its hard to explain
but what my point is, is taht the doppler effect works in the same way, like if a car is moving towards you the sound is being emitted from the car and being pushed by the speed of the car making it have a much higher pitch, when the car is going away however it drops to a lower pitch due the the sound waves being DRAGGED by the car.
there hoped this helped I guess
