The pleural cavity contains a little amount of liquid called as "pleural fluid".
<u>Explanation:</u>
The two thin serum producing membrane which gathers back itself resulted in membrane cavity of two layer pleural sac, which surrounds the lungs is termed as "pleura".
This cavity contain small amount of liquid named as pleural fluid, its function is to provide lubrication during respiration when the lungs expand and contract. Most fluid is generated via bulk flow through the parietal circulation and is reabsorbed by the lymphatic system.
Thus pleural fluid is continuously produced and reabsorbed. A few millilitres of pleural fluid is always present inside the intrapleural space in a typical 70 kg human.
Answer:
Nicolaus Copernicus
Explanation:
In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. His theory took more than a century to become widely accepted.
The length of the pendulum is 3.3 m.
The given parameters:
- Mass, m = 1.5 kg
- Angle, θ = 35⁰
- Speed, v = 3.4 m/s
<h3>What is principle of conservation of energy?</h3>
- The principle of conservation of energy states that, the total energy of a system is always conserved.
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
g(L - Lcosθ) = ¹/₂v²
gL(1 - cosθ) = ¹/₂v²
Thus, the length of the pendulum is 3.3 m.
