Oscillations occur in physics in an extremely wide range of
occurrences.They are macroscopically visible in the swinging and
cushioning of cars or suspension bridges. In Nature, however, there
is as a rule never a single oscillation but always only co ...
Electronystagmography (ENG) is an electrophysiological
diagnostic procedure for measuring the movement of the eyes.
Several electrodes measure the potential differences that are
caused by the eye movements. When looking at a moving, regular,
Heavy-metal ions may be carried into surface or ground water
from mining fields or via the waste water of galvanicor similar
production sites. They block the effect of enzymes so that the
processes in the metabolism of the organisms that are controlle ...
Demonstration experiment using wireless data transmission to a large digital to display. Heavy metal ions can seep into water courses, for example from galvanising plants or other similar industries. They have the effect of suppressing the action of enzyme ...
"A mass is not only inert but also heavy." Which is intended to
mean that not only is a force necessary to accelerate a mass, but
also that each mass in the earth's gravitional field experiences a
force, the force of weight. The force of weight is to ...
Leaf springs are thin metal plates that are elastically deformed
under load: When a force is applied to a
leaf spring, then it is subject to deformation. A characteristic of
such an elastic deformation is that the
original shape is re-for ...
We deal with friction in our everyday lives and in technology.
Without exception every movement on Earth is connected to friction,
and therefore with a loss of energy and wear. Without friction,
however, movement would not be possible at all. You coul ...
In this experiment observations are to be made on a spring
pendulum which consists of a helical spring
with a spring constant D and a mass m which is hung on it. When the
pendulum is displaced by smax and
let go of, it swings across its r ...
Why do tea or coffee get cold onstanding, but never hot?
Watch the water temperatures when a vessel containing cold water
is dipped into a hot water bath.
A quick loss of heat is sometimes not wanted. What can be done
to keep the temperature in a vessel
Measure the cooling of hot water in two different
How depends the time required to heat up water on the amount of
water when a defined heating source is available?
Heat up various amounts of water with an electric heating coil
and measure the time dependence ...
Do different liquids heat up to the same extent when subject to
the same heating?
Heat 100 g and 100 ml of water and of glycerol with an electric
heating coil and measure the temperature
in dependence o ...
In households, a great amount of energy is used to heat up water
- for showers, for washing clothes, for cooking. Exactly how much
is necessary for each degree that each mililitre of water is warmed
up? How are amount of heat, heat capacity and change ...
Quantities of heat distribute themselves so that finally all
parts that are in contact with each other have the same
temperature. If the heat capacities and the initial temperatures
are known, then the final temperature can be predicted. Or, in
