What happens to the frame of a seismograph when seismic waves arrive?

It moves with the same frequency and amplitude as the seismic waves, while the large mass suspended within it is damped from these oscillations due to it's own inertia. The relative movement between this stationary mass and the frame can then be recorded.

How do seismometers work?
AThere are a number of different types of seismometers and they all work in slightly differing ways but generally are based around the same principle. That principle is inertia. Inertia basically means that stationary masses will remain stationary until a force is applied to them. Conceptually a seismometer can be thought of as a weight or mass, suspended by springs in a frame which is bolted to the floor. When an earthquake occurs the frame which is attached directly to the floor is caused to move by the seismic waves, however the mass / weight on the spring does not as the seismic waves do not directly affect it (their effect is dampened by the inertia of the mass and the springs). If you were to attach a pencil or pen to the weight and a piece of graph paper to the frame so that they were touching the movement of the frame relative to the stationary mass would be recorded. Modern seismometers are much more complex than this but in essence rely on this principle.

As such seismometers measure the frequency and amplitude of the movements of ground surface as caused by seismic waves.
Why does a switch flood a frame?
Because it is a broadcast frame Because it is a multicast Frame Because the switch has no MAC address for it.
How does an earthquake detector work?
A Chinese earthquake detector is an old invention invented by Chang Heng[AD 78-139] and is also called a seismograph. It actually looks like vase with eight dragon heads on it and surrounding the dragon heads there are eight frogs with open mouths as if to catch the ball in each dragons mouth. It works like this;when the first tremors of an earthquake made the device vibrate,the ball fell into frog's mouths,making a sound to warn of coming danger. in its mouth is like a point of the compass,this is where the earthquake is coming from. Earthquakes are detected using a seismometer. A seismometer, also known as a seismograph, is an instrument that records movements of the ground. It is used to detect seismic waves generated by earthquakes and nuclear explosions. A seismoscope can also be used for the detection of underground movements. It indicates that motion has occurred, but does not give a continuous record of the ground movements. A seismometer consists of an inertial mass that moves in relation to the instrument frame and a method to measure the motion of the mass in relation to the frame. Ground motion causes the instrument frame to move. The motion between the frame and the mass is measured in order to detect and record the ground movements. Modern seismometers consist of a negative feedback loop that applies a magnetic or electrostatic field to resist the motion of the inertial mass. The seismometer outputs the voltage equivalent of the force required to resist the motion of the mass. The advancements in technology have led to the creation of modern earthquake-detecting instruments, which use electronic sensors and amplifiers. They cover a broad frequency range. Devices of the modern times are highly sensitive to ground movements. Teleseismometers, which cover a wide range of frequencies and strong-motion seismometers using the digital technology, are some of the latest instruments used to detect earthquakes. Earthquake detection systems can only help us forewarn of a possible earthquake by enabling early detection and near-accurate measurement of its intensity.
What should you do if you feel an earthquake coming?
you should run to a door frame and stand there with your hands on the frame. why? because that is the firmest place in the house.
What happens to a seismograph frame when a seismic waves arrive?
It moves with the same frequency and amplitude as the seismic waves, while the large mass suspended within it is damped from these oscillations due to it's own inertia. The relative movement between this stationary mass and the frame can then be recorded.
What is the frame a seismograph is attached to?
It's attached to the ground.
What is the frame of a seismograph attached to?
It's attached to the ground.
What happens when an ISL-enabled trunk receives an unencapsulated frame?
The frame is dropped.
What happens when a frame from a source MAC address different from 00a8d2e4ba27 reaches switch port 015?
The frame is dropped
What happens if an adaptor determines that a frame it has just received is addressed to a different adaptor?
It delivers the frame to the network layer

What happens if a ribosome does not read in frame?
A translation error occurs.
What happens when a frame goes bad on a vehicle?
The vehicle becomes weaker. It may bend, and anything stuck to the frame may come loose.
What is disadvantages of frame structure?
Space frame has excellent performance which is much better than other steel structure. If the span is more than 30m, space frame is more economical, safer , and with better seismic performance. So it becomes widely welcomed by the clients nowadays all over the world. The main advantages are as following: The span of space frame can be very big without columns in the middle to support the whole structure, so space frame structure is suitable for buildings covering large area. Cost of space frame Generally speaking If span≥30m, the cost of space frame is lower than the other structures. If span <30m & ≥20m, the cost of space frame is almost same to other steel structures. If span <20m, the cost of space frame is higher than other structures. Space frame structure has light self-weight. Space frame structure is safer than other traditional structures. Space frame has excellent seismic performance. Space frame is easy to install. Space frame looks more beautiful. Space frame structure is easy transport, as the sizes of components are small. Space frame can be used to all kinds of building Space frame can be produced industrially. Many kinds of roof material can be used to space frame.
What happens if you put a metal door frame in cold weather?
Why not put it on a house instead
What happens to an objects length if its close to the speed of light?
It depends on the observer's frame of reference.
