You will feel the s-wave 12.4 seconds after you felt the p-wave.
<h3>
How to find the difference in time?</h3>
The waves must travel 250 km, we know that the p-wave travels with a velocity of 6.3km/s. The time it takes to travel that distance is given by:
250km/( 6.3km/s) = 39.68s
At this point is when you feel the p-wave.
The s-wave travels at 4.8 km/s, than it will take:
250km/(4.8km/s) = 52.08 s
The difference in time is:
d = 52.08s - 39.68s = 12.4 s
This means that you will feel the s-wave 12.4 seconds after you felt the p-wave.

Answer:
The answer is 2; Lake.
Explanation:
A lake (from Latin lacus) is a large body of water (larger and deeper than a pond) within a body of land. As a lake is separated from the ocean, it is not a sea. Some lakes are very big, and people in the past sometimes called them seas. Lakes do not flow like rivers, but many have rivers flowing into and out of them.
Answer:
False. The purpose of the Darwin Finch lab was to establish that the relationship between food sources and beak shape was food availability.
Explanation:
Finches speciation was due to geographical isolation on islands and the differences in their picks were an evolutive adaptation that reflected feeding habits. Their speciation depended on or was the result of their adaptation to the island and its characteristics. The finches´ beaks evolved according to food availability. Large beaks are better for islands with larger seeds, while pointed beaks are better for getting insects out of trees.
