The reason for that is that P-waves (primary waves) travel faster than S-waves (secondary waves).
If we call

the speed of the primary waves and

the speed of the secondary waves, and we call

the distance of the seismogram from the epicenter, we can write the time the two waves take to reach the seismogram as


So the lag time between the arrival of the P-waves and of the S-waves is

We see that this lag time is proportional to the distance S, therefore the larger the distance, the greater the lag time.
Answer:
degree celsius
Explanation:
it's measured in degree Celsius
Answer:
Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Answer:
Explanation:
Ask a question that can be answered by making observations.
We have: F = m×a
Here, m = 90 Kg
a = 15 m/s²
Substitute their values into the expression:
F = 90 × 15
F = 1350 N
In short, Your Answer would be Option D
Hope this helps!
