How does wet and dry barometer work?? Thnx
tatiyna

Wet barometer - The tool works by measuring atmospheric pressure to predict incoming weather. Since the glass is only filled halfway with water, the other half is exposed to the atmosphere. When the outdoor atmospheric pressure rises, the pressure in the glass decreases, and causes the water to move down the spout.

Dry barometer - A Torricellian barometer (sometimes called a mercury barometer) is an inverted (upside-down) glass tube standing in a bath of mercury. Air pressure pushes down on the surface of the mercury, making some rise up the tube. The greater the air pressure, the higher the mercury rises.

I hope this helps!

Explain how the human body cools itself.
Annette [7]

Hi there!


There is a way that the human body cools itself, but it sounds so weird!


Did you know that when you sweat after doing something constantly, the sweat tries to cool the body down? It's true!


I learned this is physical science class, and we tested it for ourselves. We ran around a bunch of times around my old school and then we started sweating. Not too long afterwards, we started cooling down because of the sweat.


Weird, right?


Hope this helps!

Message me if you need anything else! :D

What is not a characteristic of the cortical nephrons?
Pani-rosa [81]

Answer:

Their nephron loop is closely wrapped with vasa recta.

Cortical nephrons are located in the cortex.

They form 85% of all the nephrons in the kidney. They are located mostly within superficial cortex of kidney. The loop of henle of a cortical nephron is relatively short and hence not closely wrapped with vasa recta. Efferent arteriole delivers blood to a network of peritubular capillaries.
