Explanation:
the morning of the birthday party balloon filled with the 2.5 Litre of helium
temperature is 294kelvin
the party starts at the 4 p.m.
temperature rises 305 Kelvin.
the new volume = 4 litre.

First, calculate for the distance between the given points A and B by using the equation,
<span> D = sqrt ((x2 – x1)2 + (y2 – y1)2)</span>
Substitute the known values:
<span> D = sqrt((9 – 2)2 + (25 – 1)2)</span>
<span> D = 25 m</span>
I assume the unknown here is the time it would require for the particle to move from point A to B. This can be answered by dividing the calculated distance by the speed given above.
<span> t = (25 m)/ (50 m/s) = 0.5 s</span>
<span>Thus, it will take 0.5s for the particle to complete the route. </span>
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.

Answer:
Explanation:
Given
Mass of solid uniform disk 
radius of disk 
mass of lump 
distance of lump from axis 
Moment of inertia is the distribution of mass from the axis of rotation
Initial moment of inertia of disk 
Final moment of inertia 
=Moment of inertia of disk+moment of inertia of lump about axis
In physics, a force is said to do work<span> if, when acting, there is a displacement of the point of application in the direction of the force. It is calculated by the formula W = f x d. Therefore, we calculate the problem above as follows:
W = f x d
4000 = f x 20
f = 200 N <----- FIRST OPTION</span>
