Answer:
Climate Change and Extreme Weather
Establishing the most likely causes behind an extreme weather event can be challenging, since these events are due to combinations of multiple factors, including natural variability.

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:
5.76N
Explanation:
We are given that
Distance between two charges ,
Electrostatic force=
Where k=
Substitute the values then we get
Hence, the electric force between two charges=5.76N
Answer:
Explanation:
On Earth the atmospheric presure is . This will be the pressure inside the lander. Outside, the pressure on Mars will be . This means that the net force will be outward (since inside the pressure is higher) and, since the area of the hatch is , of value:
Since 1lb in weight is equal to 4.45N, we can write:
