Explanation:
13 cmHg (centimeters of mercury) is the pressure at the bottom of a column of mercury 13 cm deep. It is the equivalent of about 17.3 kPa or 2.5 psi.
Answer:
Explanation:
Speed = distance / time
Given speed = 127 m/s .
distance = 1.58 m
time = ?
Putting the values in the formula
127 m/s = 1.58 m / time
time = 1.58 / 127 s
= 12.44 ms .
Technically all 3 of those would be correct answers. But applying the brakes would probably be the correct answer if all of the above isn't a answer.
