How long the seismologist wants the paper to last before
it runs out and he has to go and install a new roll.
The time-distance graph of seismic waves shows the relationship between the time it takes for seismic waves to travel and the distance they travel. It helps in determining the speed at which seismic waves propagate through the Earth's interior and provides information about the structure and composition of the Earth's layers.
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.
speed graph
Acceleration is indicated on a speed/time graph.
"True, the Seismic Waves change speed and direction when they encounter different materials."
To find acceleration from a speed-time graph, you need to calculate the slope of the speed-time graph. The slope at any point on the speed-time graph represents the acceleration at that specific time. If the speed-time graph is linear, then the acceleration will be constant. If the speed-time graph is curved, you can find the acceleration by calculating the slope of the tangent line at a specific point.
Slope of the graph will give you speed.
Speed (in the radial direction) = slope of the graph.
A seismogram is a record of an earthquake that's obtained from a seismic instrument. It's in the form of a graph.
Line graph.
No. The slope on a speed vs time graph tells the acceleration.
