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;
where;
= initial intensity
I = 19.95
I ≅ 20 pig callers
Answer:
As evolutionary biologists have shown, this multicellularity was linked to the rise in oxygen and thus played a significant role for life on Earth as it is today. ... By producing oxygen and evolving into multicellular forms, they played a key role in the emergence of organisms that breathe oxygen.
Explanation:
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>

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.
