Chronic stress can physically change the brain by:
- Chronic stress has the ability to shrink the
brain. It has the ability to harm one’s person learning capacity by being able
to reduce the volume of the gray matter that is a major component in a person’s
brain. It is also able to harm the memory of the person.
Nitrogen gas has a molar mass of about 28.0134 g/mol. Then we have a starting amount of
(42 g) / (28.0134 g/mol) ≈ 1.4993 mol
of N₂.
At standard temperature and pressure, one mole of an ideal gas occupies a volume of about 22.4 L. Then 42 g, or 1.4993 mol, of N₂ takes up
(1.4993 mol) × (22.4 L/mol) ≈ 33.6 L

Answer:
Explanation:
a(t)=20t i+sin(t) j +cos(2t) k
v(t)=
=
---------------eqn 1
given v(0)=i
i=
from equation 1
V(t)=----------eqn 2
now r(t)=
given r(0)=j
0i+1j+ok = 
<span>The time it takes for one wavelength to pass a fixed point is known as PERIOD.
In fact, the period is defined as the time it takes a wave to make one complete oscillation: since the wavelength is the distance between two consecutive points of the wave with same shape, it means that the time it takes for one wavelength to pass a fixed point in space is exactly the period.</span>
