It consists of a pot placed inside a bigger pot with the space
between them filled with a wet porous material, e.g. sand. How might one
achieve the best cooling effect? Low temperature or fast cooling? Here the effective
parameters are studied.

The mechanical stability of constrained spaghetti has
been studied in spaghetti accelerator. The physical process
of fragmentation is relevant to several areas of science and
technology to find relevant parameters includes : surface
energy contributions, nucleation and growth properties of
the fracture process, elastic buckling , and stress wave
propagation.

Have you ever thought about the effect of various salts on
the onion cell? for investigating and answering the
question raised in this study first, we remove the purple
epidermis of the onion cell and then take a picture of its
previous state under the microscope, in the Next step, we
use a dropper, and then pour a few drops of the salt solution
over the sample and after that by taking some pictures at
different time lapses, the changes would be recorded in the
images.

As problem mentioned we basically took two balls and
attached them through a string . By moving the point as the
pivot up and down we got to the motion of lato lato.
Two things are happening that are the key components to
this issue. The 1st one is internal collision that occur
between the balls and the second one is the periodic motion
these two balls exhibit after a while.

Deformation of the surface of a diamagnetic liquid by a
magnetic field is called the “Moses Effect”. This
deformation in water attracts particles and create a current
in the direction of the magnetic field. By calculating this
deformation, we can also measure the magnetic energy
density and the gravitational potential energy density,
which according to the law of conservation of energy must
be equal.

The magnetic pendulum is a striking example of
unpredictability in classical physics; a magnetic bob
suspended above fixed magnets on a non-magnetic surface
exhibits chaotic motion when released. In this study, we
investigate the parameters affecting the motion of the
moving magnet.

For electrophoresis, a sample containing a variety of
proteins or DNA or RNA, a small amount of it, is loaded
onto wells embedded in a porous network (such as
acrylamide-based gels). This device has two buffer
chambers and a gelation chamber, where the gel is
connected to one buffer chamber at the top and to another
buffer chamber at the bottom. After an electric field is
established between the two buffers by applying a
potential difference on both sides of this network, the
molecules in the sample begin to move at different speeds
within the porous network, which depend on their electric
charge, molecular mass, and sometimes spatial shape, and
are separated from each other.

With connection a high voltage to a fluid (e.g. deionized
water) in two beakers, a fluid bridge may be formed.
Bridge Formation and sparks are initial observations
which by theory and experiment different parameters in
this phenomenon are studied .

The interaction between a magnetic ring and a
ferromagnetic rod provides an intriguing demonstration of
physical principles. When a magnetic ring is placed at the
top of a ferromagnetic rod, its subsequent motion is
governed by a combination of magnetic forces,
gravitational forces, and frictional interactions at the
interface between the ring and the rod. This problem
allows us to explore the dynamic interplay of forces under
varying conditions, leading to a spectrum of possible
behaviors, including stationary states, pure rolling motion,
sliding motion, and combinations of rolling and sliding.

Watercourse Blockage Detection System

The waste that is thrown into the watercourses
accumulates after a while and causes the watercourses to
become clogged and the water flow stops and the water in
the watercourse flows into the alleys and streets. In
addition, the blockage of the watercourses causes animals
such as rats and vermin, etc. to gather around the
watercourses. These animals endanger human health.

Hysteresis is a nonlinear phenomenon, in which the
behavior of a system depends on its history. This is in direct
contrast to most ordinary physical systems, whose
behavior can be uniquely predicted based solely on their
current state. Hysteresis-related phenomena are rare in
nature, and it only appears in specific fringe cases with
materials that exhibit uncommon properties.

Sound is a wave of pressure, which means periodic
change in pressure is needed to produce sound. Since
common speakers are used in air and the medium is gas in
this case, we focus on propagation of sound wave in air
without loss of generality. From thermodynamics we know
that pressure of a gas is proportional to its temperature for
an ideal gas, and depends on temperature in more general
case for real gases according to Van Der Waals equation.
