Plasma osmolarity increases when you give a severely dehydrated person large amounts of pure water.
What is plasma osmolarity?The electrolyte–water balance of the body is measured by plasma osmolality. This amount can be determined in a variety of ways, including measurement and computation.
Osmolality and osmolarity are two separate measurements that are used interchangeably in everyday situations.
When you are dehydrated, osmolality rises, and when you have too much fluid in your blood, it drops.
The way your body regulates osmolality is unique. When your body's osmolality rises, your body produces antidiuretic hormone.
Hence,plasma osmolarity increases when you give a severely dehydrated person large amounts of pure water.

Answer:
B. Negative acceleration means this car is slowing down.
Explanation:
for the other screenshot
Average acceleration = change in velocity /change in time.
[a = ∆V/∆t] —this the formula.
NOTE:
u = initial velocity (velocity it started with)
v = final velocity (velocity it ended with)
t = time {the time you were given)
a = acceleration.
listing out our givens:
u =o —(the unit is m/s)
v = 40 —(the unit is also m/s)
t = 0.08 —(the unit is s) "s" means second(s).
Soo
a = 40-0 / 0.08 = 500 m/s² ( unit for velocity is m/s²)
( Remember when using the formula we subtract the initial from the final velocity.........I mean we remove the initial from final) if not you will get a negative answer or wrong answer).
also note: final velocity is always bigger in value than initial velocity EXCEPT it is in deceleration meaning for example a car that was speeding is gradually stopping then initial (the one it started with) will be bigger than the one it ended with (because as it gradually stops the speed reduces).
VELOCITY is speed in a specified direction.

A 2.2kg mass is at the origin. A 4.66kg mass is 3m to its right, and another 4.66kg mass is 3 m to its left. What is the net gravitational force on the 2.2kg mass?
Answer:
zero
Explanation:
The gravitational force between two masses is jointly proportional to the masses and inversely proportional to the square of the distance between them. The constant of proportionality is the universal gravitational constant.
__
In this scenario, the force to the right is matched by an identical force to the left from an identical mass at an identical distance. The magnitudes of the forces are equal, and their directions are opposite. The forces cancel.
The net force on the 2.2 kg mass in the center is zero.

a) The velocity of a moving body is t2 - t metres per second after a time of t seconds. Find the displacement of the body at the end of 12 seconds if the initial velocity is 0 metres per second.
Explanation:
The integral of a velocity versus time function is a displacement versus time function
So we integrate,
[tex] {t}^{2} - t[/tex]
The integral of that is
[tex] \frac{1}{3} {t}^{3} - \frac{ {t}^{2} }{2} [/tex]
Plug in 12 for t,
[tex] \frac{1}{3} (12 {}^{3} ) - \frac{12 {}^{2} }{2} [/tex]
[tex]576 - 72 = 504[/tex]
So the displacement is 504 meters to the right.
vf = 12² - 12 = 132 m/s
a = vf' = 2t-1
at t =12 s,
a = 2(12)-1 = 23 m/s²
vf²=vi²+2ad (vi=initial velocity=0)
vf²=2ad
132² = 2 x 23 x d
d = 378.78 m
