The Pressure wave is a longitudinal wave - it is a compression/rarefaction wave and has the highest velocity.
The Secondary wave is a transverse wave (side to side) and is much slower.
Longitudinal waves are called primary waves because they are the fastest seismic waves and are the first to be detected by seismographs in an earthquake. They are also known as P-waves because they are the first wave type to arrive at a seismograph station.
Both the feather and the ball will reach the ground at the same time in a vacuum due to the acceleration due to gravity being constant for all objects. However, in the presence of air resistance, the feather will take longer to reach the ground compared to the ball due to its larger surface area and lighter weight.
After each bounce, the ball reaches half of the height from which it was dropped. Since the ball was initially dropped from 10 feet, on the first bounce it will reach 5 feet, on the second bounce it will reach 2.5 feet, on the third bounce it will reach 1.25 feet, and on the fourth bounce it will reach 0.625 feet.
In a game of Quidditch, to get the Quaffle first, players from both teams typically race to reach it as the game begins. The Chasers on each team are responsible for scoring by getting the Quaffle through the opposing team's hoops.
The speed of light is faster than the speed of sound. This means that light waves, carrying visual information, will reach your eyes before sound waves reach your ears. This is why you see the fighter plane first before hearing it.
p-waves
P-waves are the first seismic waves to arrive at a seismograph station.
P
The primary waves (P-waves) are the first to reach a seismograph after an earthquake. These waves are faster than other seismic waves and can travel through both solid and liquid materials.
S-waves cannot travel through the earth's outer core as it is liquid. Surface (Love and Rayleigh) waves cause the most damage to buildings. P-waves are the first to arrive at seismograph stations.
Longitudinal waves are called primary waves because they are the fastest seismic waves and are the first to be detected by seismographs in an earthquake. They are also known as P-waves because they are the first wave type to arrive at a seismograph station.
It would take about 5-7 minutes for the primary or P-waves to reach a seismograph station in Miami, Florida from Seattle, Washington. These waves travel faster than secondary or S-waves, which would arrive a few minutes later.
The distance of a seismograph from an earthquake affects the arrival times of seismic waves. The farther the seismograph is from the earthquake, the longer it takes for the waves to reach it. This relationship allows scientists to calculate the epicenter of the earthquake based on the differences in arrival times recorded by different seismographs.
The time it takes for seismic waves to reach the seismograph can be used to calculate the distance between the epicenter and seismograph. By knowing the average speed of seismic waves in the earth, the time difference between the arrival of P- and S-waves can be used to determine the distance.
when waves from an earthquake reach the instrament, the inertia of the weight keeps it stationary, while earth and the support vibrate. Seismographs amplify and electronically record ground motion.
A surface wave is the last seismic wave to arrive after an earthquake.
The first mission on Reach is Noble Actual. The first PLAYABLE mission is Winter Contingency.
