Explanation:
Answer: As you've learned, some viruses are released when the host cell dies, and other viruses can leave infected cells by budding through the membrane without directly killing the cell.
Explanation:
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.

The three(3) potential challenges or important points to consider when conducting a data collection are described below.
Data collection is a detailed process that is used in gathering and measuring information from a selected source by a researcher.
To perform a data collection, the following important points are to be considered :
- Cost of data: before data collection, a researcher should check if the data that is being considered is affordable. this is done to avoid quitting.
- Accuracy: there are different types of data collection techniques these include: questionnaires, interviews, focus groups, observation and case studies. the data collection technique that should be chosen should provide the most accurate results.
- Validity of data: if your findings will truly represent the phenomenon you are claiming to measure, then the data collected is valid.
Therefore the above important points needs to be considered during data collection.
