The answer to this question is false
A wave is basically propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.
Answer:
211 mmHg
Explanation:
Absolute Pressure = Gauge Pressure + Atmospheric pressure
128 = Gauge Pressure + 100
Gauge Pressure = 28 KPa = 28 × 10³ Pa
Also Gauge Pressure = ρgh
ρ = density = 13550 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = pressure head = ?
28 × 10³ = 13550 × 9.8 × h
h = 28000/(13550 × 9.8)
h = 0.211 m = 211 mm
Here it is. I used the surface charge density σ as q/Area, and then wrote it out in terms of q at the end
