Answer: Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. This image shows the Orion Nebula or M42 . Stage 2 - A region of condensing matter will begin to heat up and start to glow forming Protostars.

In a pig caller can produce a sound intensity level of 107 dB. How many pig callers would be needed to generate an intensity lev
myrzilka [38]

Answer:

20 pig callers

Explanation:

Given that:

A pig caller produced intensity level of  a sound = 107 dB

To find how many pig callers required to generate an intensity level of 120 dB;

we have:

120 dB - 107 dB = 13 dB

Taking the logarithm function;

10 \ log \bigg(\dfrac{I}{I_o} \bigg) = 13 \ dB

where;

I_o = initial intensity

log \bigg(\dfrac{I}{I_o} \bigg) = 1.3

\dfrac{I}{I_o}=  10^{1.3 }

I = 19.95I_o

I ≅ 20 pig callers

A 5.00 kg mass is placed on top of a vertical spring, which compresses a distance of 3.13 cm. Calculate the force constant (in N
77julia77 [94]

Answer:

<h2>1567.09 N/m</h2>

Explanation:

Step one:

given data

mass m=5kg

compression x= 3.13cm to m= 0.0313m

<em>According to Hooke's law, provided the elastic limit of an elastic material is not exceeded the extension e is directly proportional to the applied force</em>

F=ke

where

k= spring constant in N/m

e= extension/compression in

Step two:

assume g= 9.81m/s^2

F=mg

F=5*9.81

F=49.05N

substitute in the expression F=ke

49.05=k*0.0313

k=49.05/0.0313

k=1567.09 N/m

<u>The force constant (in N/m) of the spring is 1567.09 N/m</u>

Do you believe that a patient with late-stage Alzheimer's
strojnjashka [21]

The surgery would not be a hip replacement but would be resetting the broken bone with pins ad wires at late-stage Alzheimer's disease.

Older adults who have surgery with well-known anesthesia can also enjoy a modest acceleration of cognitive decline, even years later. but there may be no proof of a hyperlink to Alzheimer's disease, in step with new research from Mayo sanatorium.

Older adults who have surgical treatment with fashionable anesthesia can also experience a modest acceleration of cognitive decline, even years later. but there's no evidence of a link to Alzheimer's sickness, according to new research from Mayo sanatorium. most hip fractures require surgical treatment, generally within one of damage. hardly ever, hip fractures can be handled without surgical operation, usually in patients who may be too unwell or in a small group of patients that have recovery, non-displaced fractures that have been diagnosed weeks after injury.
