Question

If you were designing your own seismograph, which features would be important to include? 1) A pole attached to a hanging weight 2) A loose spring so the spring does not disrupt the pen's motion 3) A heavy base with the durability to endure the quake 4) A tall, heavy post so the device tips easily 5) A heavy, hanging weight to maintain pen contact with the drum

Answer 1

When designing a seismograph, important features to include are a pole attached to a hanging weight, a loose spring, a heavy base with durability, and a heavy hanging weight.

Step-by-step explanation:

When designing a seismograph, there are several important features to include:

1. A pole attached to a hanging weight: This provides the device with stability and ensures accurate readings.
2. A loose spring: The spring should be loose so that it does not disrupt the pen's motion while recording the seismic waves.
3. A heavy base with durability: The seismograph needs a heavy base to withstand the shaking during an earthquake and ensure it stays in place.
4. A tall, heavy post: A tall, heavy post is not necessary as it may cause the device to tip easily.
5. A heavy, hanging weight: A heavy, hanging weight is important to maintain contact between the pen and the drum, ensuring accurate recordings.

Answer 2

To design an effective seismograph, key features to include are a heavy base for stability during quakes, a pole to support the weight, and a heavy hanging weight to maintain pen contact with the drum.

Step-by-step explanation:

A seismograph is an instrument used to detect and record earthquakes. The design must prioritize stability and sensitivity to accurately capture seismic activity.

1) Heavy Base: The heavy base ensures stability during an earthquake, preventing the seismograph from moving excessively and maintaining its position.

2) Pole with Hanging Weight: A pole attached to a hanging weight serves as a support structure. The weight helps to anchor the seismograph and prevents it from being displaced during ground movements.

3) Heavy Hanging Weight: The hanging weight is crucial for maintaining pen contact with the drum. This weight ensures that the pen remains in contact with the recording surface, allowing accurate and continuous tracking of ground motion.

Including features like a loose spring or a tall, heavy post that tips easily could compromise the seismograph's functionality and accuracy, as these might introduce unnecessary movements or disruptions.
