A seismogram shows that P waves travel faster than S waves. The answer is letter D. This is because P waves can push and pull the sound waves through a liquid or solid medium. The S wave can only move to the solid medium and solids have more compact molecules than the liquid so it travels slow.

Explanation:
Because P waves are the fastest seismic waves, they will ordinarily be the original 1 that your seismograph records. The following set of seismic waves on your seismogram will be the S waves. These are normally higher than the P waves. Often they are the only waves filmed a long distance from medium-sized earthquakes.

Explanation:
component equal to 5 m/s and a vertical component
equal to 6 m/s.
At the highest point of the projectile's flight, what is (a) the horizontal component of its
velocity and
(b) the vertical component of its velocity?
Explain.
The horizontal component of a projectile's velocity remains constant throughout its flight. Hence, at the highest point, its value is the same as the initial, 5 m/s. The vertical component, on the other hand, becomes zero at the highest point.
For a projectile, the horizontal component of motion and the vertical component of motion are independent. Therefore, the horizontal component of velocity remains constant throughout the flight as long as there is no air resistance. Hence, at the highest point of a projectile's flight, the horizontal velocity (a) remains the same, i.e., 5 m/s.
However, for the vertical component, it is subjected to the acceleration due to gravity. At the highest point, the vertical component of velocity (b) becomes zero, because it has momentarily stopped before changing direction and accelerating downwards.

Answer:Consider again the cannonball launched by a cannon from the top of a very high cliff. Suppose that the cannonball is launched horizontally with no upward angle whatsoever and with an initial speed of 20 m/s. If there were no gravity, the cannonball would continue in motion at 20 m/s in the horizontal direction. Yet in actuality, gravity causes the cannonball to accelerate downwards at a rate of 9.8 m/s/s. This means that the vertical velocity is changing by 9.8 m/s every second. If a vector diagram (showing the velocity of the cannonball at 1-second intervals of time) is used to represent how the x- and y-components of the velocity of the cannonball is changing with time, then x- and y- velocity vectors could be drawn and their magnitudes labeled. The lengths of the vector arrows are representative of the magnitudes of that quantity. Such a diagram is shown below.

B. Current is directly proportional to voltage.
C. As resistance increases, current decrease.
D. If the voltage of a bulb is 12 V, and the resistance is 4 ohms, then the current must be 5 A.
Answer:
B.
Explanation:
Current is directly proportional to voltage and inversely proportional to the resistance.
The statement that is true is:
B. Current is directly proportional to voltage.
and
C. As resistance increases, current decreases.
B. the origin.
C. the starting line.
D. an intersection point.
the point where they meet at is called the origin
B) They are absorbed
C) The change into P-waves
D) They change into L-waves
Answer:
B) They are absorbed
Explanation:
B is correct because S waves can only travel through solid materials. When they hit liquid materials they are absorbed in and undetectable.
Answer:
B) They are absorbed
Explanation:
When they hit the liquid core, S-waves are no longer able to be detected. While P-waves bounce off the liquid core, S-waves are absorbed at the core.
