1. your ear drums feel like they pop when you go deep enough under water. kinda feels like bricks. and it hurts if you stay under to long.
2. this could be a reaction from fluid pressure yes. can could be avoided by getting wax ear plugs however even with ear plugs going deep enough under water can still make your ears "pop" due to pressure but at high surfaces it would avoid that.
Please rate me brainliest?
C im pretty sure?.........
A 1 complete revolution corresponds to an angular displacement of 2π rad, or 360º. (So there are 180º for every π rad.) Also, there are 60 seconds to 1 minute. So, the angular velocity in rad/s is
(2000 rev/min) * (2π rad/rev) * (1/60 min/s) = 200π/3 rad/s
or approximately 209.44 rad/s.
B First convert the angular velocity to degrees per second (º/s):
(200π/3 rad/s) * (180/π º/rad) = 12,000 º/s
We want to find the time <em>t</em> it would take for the propeller to turn 36º:
36º = (12,000 º/s) <em>t</em>
==> <em>t</em> = 36º / (12,000 º/s) = 3/1000 s
or approximately 0.003 s.

b) 3025.6 m
Explanation:
The picture attached shows the full explanation for the problem.
Answer:
According to this law, the force exerted between two point charges
i) is directly proportional to the product of their strengths.
ii) is inversely proportional to the square of the distance between them. and
iii) is inversely proportional to the absolute permittivity of the surrounding medium.
This is known as Coulomb's Law.
