Explanation:
760 mmHg (millimeters of mercury) is a measure of atmospheric pressure. It represents the height of a column of mercury at which the static pressure at the bottom is equal to the atmospheric pressure.
1 atm = 760 mmHg = 101,325 Pa = 14.7 psi
Conductivity would be the property.
Answer: The answer is A) 49 N(Newtons).
Answer:20000m/s
Explanation:
Frequency=10khz
Frequency=10x1000
Frequency=10000hz
Wavelength=2m
Speed= frequency x wavelength
Speed=10000 x 2
Speed=20000
speed=20000m/s
