gulaghasi [49]

He has a mass of 56 kg.

The equation given is PE = mgh.

PE = 4620 J

h = 8.4

g = 9.8

Therefore:

4620 = 82.32m

m = 4620/82.32
m = 56 (rounded to two significant digits)

dolphi86 [110]

After oxygen has been administered, the next priority intervention the nurse would initiate for a patient with a pulmonary embolus is the administration of IV Heparin.

<h3>What is Heparin?</h3>

Heparin is a prescription medicine used to treat and prevent symptoms of blood clots caused by medical conditions or medical procedures. Heparin may be used alone or with the other medications. Heparin belongs to a class of drugs called the Anticoagulants, Cardiovascular, Anticoagulants, Hematologic.

<h3>What are the side effects of Heparin?</h3>

Heparin may cause serious side effects including:

skin warmth or discoloration,

chest pain,

irregular heartbeats,

shortness of breath,

dizziness,

anxiety,

sweating,

unusual bleeding or bruising,

severe pain or swelling in your stomach, lower back/growing

dark or blue-colored skin on your hands/feet,

nausea,

vomiting,

loss of appetite,

unusual tiredness,

bleeding that will not stop,

nosebleed,

blood in the urine or stool,

black or tarry stools,

coughing up blood or vomit that looks like the coffee grounds,

skin changes where the medication was injected,

fever,

chills,

runny nose,

watery eyes,

easy bruising,

purple or red spots under your skin,

sudden numbness or weakness,

problems with vision or speech, and

swelling or redness in an arm or leg

You find an unmarked blue laser on your way to physics class. When you get to class you realize you can determine the wavelength

Afina-wow [57]

Answer:

λ = 451.7 nm

Explanation:

The expression for the constructive interference of the double diffraction experiment is

d sin θ = m λ

let's use trigonometry

tan θ = y / L

how the experiment occurs at very small angles

tan θ = sin θ / cos θ = sin θ

sin θ = y / L

we substitute

d y / L = m λ

λ = $\frac{d \ y}{m \ L}$

let's calculate

λ = $\frac{0.342 \ 10^{-3} \ 2.80 \ 10^{-3} }{1 \ 2.12 }$

λ = 4.51699 10⁻⁷ m

λ = 4.517 10⁻⁷ m (109 nm / 1m)

λ = 451.7 nm

A brass alloy is known to have a yield strength of 240 MPa (35,000 psi), a tensile strength of 310 MPa (45,000 psi), and an elas

Karo-lina-s [1.5K]

Answer:

Here Strain due to testing is greater than the strain due to yielding that is why computation of load is not possible.

Explanation:

Given that

Yield strength ,Sy= 240 MPa

Tensile strength = 310 MPa

Elastic modulus ,E= 110 GPa

L=380 mm

ΔL = 1.9 mm

Lets find strain:

Case 1 :

Strain due to elongation (testing)

ε = ΔL/L

ε = 1.9/380

ε = 0.005

Case 2 :

Strain due to yielding

$\varepsilon' =\dfrac{S_y}{E}$

$\varepsilon' =\dfrac{240}{110\times 1000}$

ε '=0.0021

Here Strain due to testing is greater than the strain due to yielding that is why computation of load is not possible.

For computation of load strain due to testing should be less than the strain due to yielding.
