Velum
-includes the soft palate and the uvula, begins where the palatine bone ends
-muscular hydrostat; connected anteriorly to bone but the velum itself is only muscle and connective tissue
-has 4 layers vertically; top to bottom: connective tissue/tendon, front to back muscles, side to side muscles, glandular tissue (visible through the oral cavity)
-the middle is the most muscle rich and makes contact with the pharyngeal wall during contraction in a knee-like motion
-no muscle fibers in the front and very few in the uvula

A 0.45 kg soccer ball changes its velocity by 20.0 m/s due to a force applied to it in 0.10 seconds. What force was necessary fo

frutty [35]

Answer:

90 N

Explanation:

The force applied to the ball is given by:

$F=\frac{\Delta p}{\Delta t}$

where

$\Delta p$ is the change in momentum of the ball

$\Delta t$ is the time taken

The change on momentum of the ball is:

$\Delta p=m\Delta v=(0.45 kg)(20 m/s)=9 kg m/s$

So, the force applied is

$F=\frac{9 kg m/s}{0.10 s}=90 N$

Ratling [72]

Answer:

for C-Cl bond $\lambda_1=3.66\times 10^{-9}\ m$

for O-O bond $\lambda_2=2.43\times 10^{-9}\ m$

Explanation:

We have the bond enegy for C-Cl, $BE_1=327\ kJ.mol^{-1}= 327000\times 1.66\times 10^{-22}\ J\ per\ molecule$

bond enegy for C-Cl, $BE_2=494\ kJ.mol^{-1}= 494000\times 1.66\times 10^{-22}\ J\ per\ molecule$

<u>Now as we know the energy of electromagnetic waves is given by:</u>

$E=h.\nu$

here E = BE

<u>Then for C-Cl:</u>

$327000\times 1.66\times 10^{-22}=6.63\times 10^{-34}\times \nu_1$

$\nu_1=8.18733\times 10^{16}\ Hz$

Now wavelength:

$\lambda_1=\frac{c}{\nu_1}$

$\lambda_1=\frac{3\times 10^8}{8.18733\times 10^{16}}$

$\lambda_1=3.66\times 10^{-9}\ m$

<u>For O2:</u>

$494000\times 1.66\times 10^{-22}=6.63\times 10^{-34}\times \nu_2$

$\nu_2=1.236863\times 10^{17}\ Hz$

Now wavelength:

$\lambda_2=\frac{c}{\nu_2}$

$\lambda_2=\frac{3\times 10^8}{1.236863\times 10^{17}}$

$\lambda_2=2.43\times 10^{-9}\ m$
