How do you stop ultrasonic waves?
With a seismograph. While professional seismographs use electronic transducers to detect small movements of a mass, a very simple one can be built with a simple pendulum having a pen attached to it to draw its movements on a sheet of paper.
Does the pen in a seismometer work?
Yes, the pen in a seismometer works by recording the motion of the ground during seismic events. When an earthquake occurs, the base of the seismometer moves while the pendulum or mass remains relatively stationary due to inertia. This relative motion causes the pen to trace a line on a rotating drum or paper, creating a seismogram that reflects the intensity and duration of the seismic waves.
How a seismograph looks like?
A seismograph typically consists of a drum or digital display connected to a sensing device that records ground vibrations caused by earthquakes. The sensing device, typically a pendulum or mass on a spring, produces a trace on the paper or screen to show the intensity and duration of the seismic waves. Modern seismographs can also use electronic sensors to capture seismic data digitally.
How does an aneroid barometer works?
To make a record of the air pressure and how it's changing, and aneroid is connected connected with a device that records air pressure, making it an aneroid barograph. An aneroid is a flexible metal bellow that has been tightly sealed after having some air removed. Higher atmospheric pressures squeeze the metal bellows while lower pressures allow it to expand. The aneroid barograph consists of a slowly rotating cylinder with paper on it that can give up to a week's worth of air pressure records before new paper is needed. As you can see in the graphic above, a pen at the end of a lever attached to the aneroid moves up and down according to pressure changes and records the pressure on the paper wrapped around the cylinder.The aneroid barometer has some advantages over a Mercury barometer because it is much smaller and can also record a week's worth of data. The aneroid barometer is the heart of altimeters used in modern aviation.
When a tree is cut into paper is it a physical change?
Yes, cutting a tree into paper is a physical change because the tree's form is being altered without changing its composition. The paper still consists of the same material as the tree (cellulose), just in a different form.
Why degree of amplitude of simple pendulum should not exceed 5?
wind resistance cannot be ignored in considering a simple pendulum. The wind resistance will be proportional to a higher power of the velocity of the pendulum. A small arc of the pendulum will lessen this effect. You could demonstrate this effect for yourself. A piece of paper attached to the pendulum will add to the wind resistance, and you can measure the period both with and without the paper.
How does an old seismograph work?
The seismograph works as follows. A pen, along with a particular calculated amount of (small) weight is attached to a spring. The other end of the spring is attached to a heavy and stable(so that it can with stand the earthquakes) base support. When an earth quake occurs, the movement of the smaller weight is recorded on a roll of moving paper by the pen. Then the extent of the earthquake is measured by those graphs(seismographs).
How does a kymograph works?
A kymograph is an instrument used to record changes in pressure, movement, or other physical phenomena over time. It typically consists of a rotating drum covered with a strip of paper, which moves at a constant speed. As a physiological event occurs, such as muscle contractions or heartbeats, a stylus attached to a lever traces the corresponding changes onto the paper, creating a graphical representation. This allows researchers to visualize and analyze the dynamics of the recorded events.
How do you slow or speed up the pendulum?
To slow down a pendulum, you can increase the air resistance by adding a larger surface area like a piece of paper or foam. To speed up a pendulum, decrease the air resistance by using a smaller surface area and ensuring the pendulum has a longer length. Alternately, you can adjust the angle at which the pendulum is released for different speeds.
Do you expect paper clips to be attached or not attached to a magnet?
well it depends. colorful paper clips won't attach to a magnet. just plain ones do.
Why the pendulum of seismograph remains at rest?
Just like the first law of motion and object at rest remains at rest unless acted uponan unbanlaced foce
