Air flows from high pressure to low pressure. So does water.
So do populations of people and animals, but that's another
story.
When you reduce the pressure in your lungs, air flows into them
from outside, and you inhale. When you increase the pressure
in your lungs, air flows out of them to the outside, and you exhale.
I haven't seen a whale in about 30 years, and they may have changed
since then. But the last time I saw some, air and spray were blowing
OUT of their blow-holes. As soon as I saw that, I said to myself:
"Self ! The pressure inside that creature's body must be greater than
the outside atmospheric pressure, and that's why the air is flowing out,
from the higher pressure to the lower pressure."
Answer:
To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. or v2 = u2 + 2as and this equation of motion can be used to find the final velocity or the distance travelled if the other values are given.
Explanation:
v= u + at
s =( u + v ) t /2
s = ut + at2/2
v2 = u2 + 2as
Answer:
A. The volume of the object
Explanation:
First of all, it can only PROBABLY be A or D
But why is it only A?
- Mass = The amount of matter in an object (nothing related here)
- Volume = How much space is the object taking (super related here)
It's VOLUME here and not MASS here because:
- It it would be Mass, then the object size could be anything, but the liquid wouldn't move as much higher.
- But because it is Volume, it is taking space, which makes the liquid move
- If the Mass would be the answer, then it would be totally not related, because mass isn't related over here, it matters about size.
<h2>
Hence, A. The volume of the object </h2>
is your answer!!!!
Answer:
= 0.55 m
Explanation:
A standing wave is characterized by anti-nodes and nodes.
Antinodes are points on a standing wave at maximum amplitude, while nodes are points on the standing wave that are stationary and have zero amplitude.
The distance between two adjacent nodes or two adjacent anti-nodes is equivalent to half the wavelength.
Therefore, in this case the half wavelength is 27.5 cm.
Thus, wavelength = 27.5 × 2
= 55 cm
<u>= 0.55 m</u>
The branch of science which deals with celestial objects, space, and the physical universe as a whole.
Online definition so if you’re using it for school work I recommend re-wording!
