ICD-10-CM codes are -S02.2XXA, W21.01XA, Y93.61, Y92.830

S02.2 for Fracture, Traumatic/Nasal (Bone(s)), ICD-10-CM Alphabetic Index. Both the open fracture code and the dislocation code are not reported. Only the fracture code is provided if a fracture and a dislocation happen at the same place. Search for "dislocation/with fracture" in the alphabetical index to be sent to a doctor. A closed fracture is a fracture with displacement. To report the conditions leading up to the injury, external cause codes are utilized. Look for Struck (accidentally) by/ball (struck) (thrown)/football W21.01 in the ICD-10-CM External Cause of Injuries Index. Seven characters are required in the Tabular List to finish the code. For the first encounter, X is utilized as a stand-in for character number six, and character number seven is given the letter A.

The interstellar clouds called molecular clouds are _________.

ira [324]

Answer:

nebulas and they are the cool clouds in which stars form

Explanation:

The stars are born by chance. Fragments of matter are gathered from the cool clouds of gas and dust that float in space, the so-called nebulas. These particles are added by gravitational attraction to form a large mass.

This conglomerate, due to the effect of gravity, contracts on itself and as a consequence increases in its center, density, pressure and heat. In this way, atoms move faster and collide with each other. Under these conditions, nuclear fusion reactions soon begin. When they start the star is born.

olasank [31]

Assuming each trial represents 1000years, and <u>rock </u>samples were found, the rock sample will be given half-life of

The rock sample will be $2000years$ old

<h3>Isotope</h3>

We know that the parent Isotope remaining is given by the expression

$\frac{1}{2}^n$

where,

n = number of half lives passed

<h3>lokium Isotope</h3>

From the question, the parent Isotope remaining is $25\%$ lokium

$0.25 = \frac{1}{4} = \frac{1}{2^2} = \frac{1}{2}^2$

Therefore,

$\frac{1}{2}^2$ means 2 half lives have passed.

If from the question,

1 half life = 1000years

<h3>Rock age</h3>

Therefore,

The rock sample's age = $2*1000 = 2000years$

anygoal [31]

Answer:

2630250 N/C, horizontally left

0

$1.67\times 10^{-8}\ s$

1434.825 N/C, horizontally left

Explanation:

m = Mass of particle

u = Initial velocity = $4.2\times 10^6\ m/s$

v = Final velocity = 0

t = Time taken

s = Displacement = 3.5 cm

q = Charge of particle = $1.6\times 10^{-19}\ C$

Force is given by

$F=qE$

Acceleration is given by

$a=\dfrac{F}{m}\\\Rightarrow a=\dfrac{qE}{m}\\\Rightarrow a=\dfrac{1.6\times 10^{-19}\times E}{1.67\times 10^{-27}}\\\Rightarrow a=95808383.23353E$

$v^2-u^2=2as\\\Rightarrow v^2-u^2=2\times 95808383.23353Es\\\Rightarrow E=\dfrac{0^2-(4.2\times 10^6)^2}{2\times 95808383.23353\times 0.035}\\\Rightarrow E=-2630250\ N/C$

Magnitude of electric field is 2630250 N/C

Direction is horizontally to the left

The angle counterclockwise from left is zero.

$a=\dfrac{F}{m}\\\Rightarrow a=\dfrac{qE}{m}\\\Rightarrow a=\dfrac{1.6\times 10^{-19}\times -2630250}{1.67\times 10^{-27}}\\\Rightarrow a=-2.52\times 10^{14}\ m/s^2$

$v=u+at\\\Rightarrow t=\dfrac{v-u}{a}\\\Rightarrow t=\dfrac{0-4.2\times 10^6}{-2.52\times 10^{14}}\\\Rightarrow t=1.67\times 10^{-8}\ s$

The time taken is $1.67\times 10^{-8}\ s$

Acceleration is given by

$a=\dfrac{F}{m}\\\Rightarrow a=\dfrac{qE}{m}\\\Rightarrow a=\dfrac{1.6\times 10^{-19}\times E}{9.11\times 10^{-31}}\\\Rightarrow a=175631174533.4797E$

$v^2-u^2=2as\\\Rightarrow v^2-u^2=2\times 175631174533.4797Es\\\Rightarrow E=\dfrac{0^2-(4.2\times 10^6)^2}{2\times 175631174533.4797\times 0.035}\\\Rightarrow E=-1434.825\ N/C$

Magnitude of electric field is 1434.825 N/C

Direction is horizontally to the left

A machine uses an input force of 200 newton to produce an output force of 800 newton . What is the mechanical advantage of this

Zinaida [17]

Answer:

M.A = 4

Explanation:

mechanical advantage( force ratio) is simply the ratio of output force to input force or ratio of load to effort.

From the question,

input force = 200 N

output force = 800 N

M.A = 800 ÷ 200

M.A = 4
