The final atmospheric pressure is
Explanation:
Assuming that the temperature of the air does not change, we can use Boyle's law, which states that for a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume. In formula,
where
p is the gas pressure
V is the volume
The equation can also be rewritten as
where in our problem we have:
is the initial pressure (the atmospheric pressure at sea level)
is the initial volume
is the final pressure
is the final volume
Solving the equation for p2, we find the final pressure:

Answer: 0.683
Explanation: The relationship between a car moving along a curve and the frictional force is given below as
us×g = v²/r
Where us = coefficient of static friction =?, g = acceleration due to gravity = 9.8 m/s², v = 22.4 m/s and r = 75m
By substituting the parameters, we have that
us×9.8 = 22.4²/ 75
us ×9.8 = 501.76/75
us ×9.8 = 6.690
us = 6.690/9.8 = 0.683
It would help if there are some options, but some common sources:

A metal spoon. Because metal travels the fastest
Ha! Lot of words but the question itself is easy.
The answer is 2.5 times 10 to the 5th power.
The main part of the numbers has the decimal point placed after the first digit.
Then for what number of power, you just count the number of decimal places moved.
I hope this helps you.
