Answer:
The taken is
Explanation:
Frm the question we are told that
The speed of car A is
The speed of car B is
The distance of car B from A is
The acceleration of car A is
For A to overtake B
The distance traveled by car B = The distance traveled by car A - 300m
Now the this distance traveled by car B before it is overtaken by A is
Where is the time taken by car B
Now this can also be represented as using equation of motion as
Now substituting values
Equating the both d
substituting values
Solving this using quadratic formula we have that
The density of mercury is 13560 kg/m³.
Therefore the density of water is about 1000 kg/m³.
1 atm pressure is 101325 Pa.
g = 9.8 m/s²
The height of a water column, h, needed to measure 1 atm is given by
(1000 kg/m³)*(9.8 m/s²)*(h m) = 101325 Pa
h = 1013225/9800 = 10.3393 m = 1033.93 cm
Answer: 10.339 m or 1033.9 cm
