Explanation:
To solve this problem, we must have the full description of this problem, by doing an internet search we can find a problem with the same description and with the respective question.
<u>Description of the problem</u>
<u />
"Vertically oriented circular disks have strings wrapped around them. The other ends of the strings are attached to hanging masses. The diameters of the disks, the masses of the disks, and the masses of the hanging masses are
given. The disks are fixed and are not free to rotate. Specific values of the variables are given in the figures. Rank these situations, from greatest to least, on the basis of the magnitude of the torque on the disks. That is, put first the situation where the disk has the greatest torque acting on it and put last the situation where the disk has the least torque acting on it."
<u>For case D</u>
<u />
T = (20/2)*800 = 8000 [g-cm]
<u>For case A</u>
<u />
T = (20/2)*500 = 5000 [g-cm]
<u>For case C</u>
<u />
T = (10/2)*500 = 2500 [g-cm]
<u>For case B</u>
<u />
T = (10/2)*200 = 1000 [g-cm]
In this way it has been organized from the largest to the smallest torque present in each of the cases.
A cardiac pacemaker can be affected by a static magnetic field as small as 1. 7 mt. pacemaker wearer comes to a long, straight wire carrying 28 amperes.
A pacemaker is a device that regulates an unsteady heartbeat. A pacemaker is inserted into one or more cardiac chambers using flexible, insulated wires called leads. The electrical pulses needed to change the heart rate are delivered by these lines. Some of the most recent pacemakers don't need leads.
The risk of problems is often quite low while having a pacemaker put. The primary worry is that the pacemaker will no longer be able to regulate the heartbeat due to a malfunction or a wire that has moved out of place. The average patient lived 101.9 months (or 8.5 years) after having a pacemaker implanted; at 5, 10, 15, and 20 years later, 65.6%, 44.8%, 30.8%, and 21.4% of patients were still living, respectively.

To solve this problem it is necessary to apply the concepts related to pressure as a unit that measures the force applied in a specific area as well as pressure as a measurement of the density of the liquid to which it is subjected, its depth and the respective gravity.
The two definitions of pressure can be enclosed under the following equations
Where
F= Force
A = Area
Where,
Density
g = Gravity
h = Height
Our values are given as,
If we make a comparison between the lid and the tube, the diameter of the tube becomes negligible.
Matching the two previous expressions we have to
Re-arrange to find h
Therefore the height of water in the tube is 7.9cm
