Answer:
my day is just starting but its going good so far thanks me asking
Explanation:
Answer:
A
Explanation:
reduced precipitation is the cause of drought.
Answer:
1. The time difference between the arrival of the first P-Wave and S-Wave would be less than 4 minutes.
Explanation:
S waves are slower than P waves, even if emitted at the same time. In this case, we can say that if a station is located close to the earthquake epicenter, the station would receive these waves quickly. The P wave would be received first, since it has a higher speed, the S wave would arrive soon. As you did not provide the times when each wave was emitted, we cannot accurately state the time when each wave would be perceived by the station. However, as the station is close to the earthquake, we can say that the time difference between P and S waves would be seconds, that is, less than 4 minutes.
Known Variables:
Δy = 1.5 m
v0 = 30m/s at 60° above the horizontal.
t = 4.0 s
a. vfy = v0y + at
0 = 30sin(60) + (-9.8)t
-25.98 = -9.8t
t = 2.65.
4-2.65 = 1.35s.
Δy = v0yt + at^2/2
Δy = 25.98(2.65) + (-9.8)(2.65)^2/2
Δy = 34.44 m
1.5 + 34.44 = 35.94 m.
Δy = v0t + at^2/2
Δy = (-9.8)(1.35)^2/2
Δy = -8.93.
35.94 - 8.93 = 27.01 m.
b. vfy = v0y + at
0 = 30sin(60) + (-9.8)t
-25.98 = -9.8t
t = 2.65.
Δy = v0yt + at^2/2
Δy = 25.98(2.65) + (-9.8)(2.65)^2/2
Δy = 34.44 m
1.5 + 34.44 = 35.94 m.
vfy = v0y + at
vfy = (-9.8)(1.35)
vfy = -13.23 m/s.
I might have gone wrong somewhere so please check my answer! Cheers!
