answer:The ventilation system for the dome home would be a critical component, ensuring a safe and healthy indoor environment. Given the partially underground design, the dome home would require a specialized ventilation system that can provide a reliable air supply, remove stale air, and maintain a consistent indoor air pressure. One possible solution would be to incorporate a network of pipes and vents that connect the dome home to the surface, providing a dedicated air intake and exhaust system. This system could be designed to draw in fresh air from the surface, filter it, and then circulate it throughout the dome home. The air intake pipes could be protected with a debris-catching mesh or screen to prevent dust, leaves, and other contaminants from entering the system. To ensure optimal air quality, the dome home could be equipped with a multi-stage air filtration system. This could include a pre-filter to capture larger particles, such as dust and pollen, followed by a HEPA (High Efficiency Particulate Air) filter to remove 99.97% of particles as small as 0.3 microns. Additionally, the system could include an activated carbon filter to remove gases, odors, and volatile organic compounds (VOCs). For air purification, the dome home could incorporate a UV (Ultraviolet) light system, which would help eliminate bacteria, viruses, and other microorganisms. This system could be integrated into the ventilation system, providing a comprehensive approach to air purification. To maintain a consistent indoor air pressure, the ventilation system could be designed to automatically adjust airflow rates in response to changes in outdoor weather conditions. This would help prevent the buildup of positive or negative pressure inside the dome home, which could compromise its structural integrity. The dome home could also be equipped with a network of sensors and monitoring systems to track indoor air quality, temperature, and humidity. This would enable occupants to monitor and adjust the ventilation system as needed, ensuring a comfortable and healthy indoor environment. In terms of the technical details, the ventilation system could be designed as follows: * Air intake pipes: 6-8 inches in diameter, made from durable, weather-resistant materials such as PVC or stainless steel * Air filtration system: multi-stage, with a pre-filter, HEPA filter, and activated carbon filter * Air purification system: UV light system, integrated into the ventilation system * Ventilation rate: adjustable, with a range of 0.5-2.0 air changes per hour (ACH) * Sensors and monitoring systems: temperature, humidity, air quality, and pressure sensors, connected to a central control unit or hub. By incorporating a well-designed ventilation system, air filtration system, and air purification system, the dome home would provide a safe, healthy, and comfortable living environment, even in the most extreme weather conditions.

answer:Let's denote the number of members in the group as ( n ) and the average height in centimeters as ( h ). According to the problem, each member contributes ( n times h ) paise. The total collection is Rs. 3625.25, which is equivalent to ( 362525 ) paise (since 1 Rupee = 100 paise). The total collection can also be expressed as the contribution per member times the number of members, which is ( n times (n times h) ). So we have the equation: [ n times (n times h) = 362525 ] We can simplify this to: [ n^2 times h = 362525 ] We are asked to find the number of members, ( n ), but we don't have the value of ( h ). However, we can deduce that ( n^2 ) must be a factor of ( 362525 ). Let's find the factors of ( 362525 ) to determine the possible values of ( n^2 ). ( 362525 ) can be factored as follows: ( 362525 = 5 times 72505 ) ( 72505 = 5 times 14501 ) ( 14501 ) is a prime number. So, ( 362525 = 5^2 times 14501 ) Since ( n^2 ) must be a factor of ( 362525 ), and ( n ) must be an integer, the only square factor of ( 362525 ) that makes sense is ( 5^2 ), because ( 14501 ) is not a perfect square. Therefore, ( n^2 = 5^2 ) and ( n = 5 ). So, the number of members in the group is ( boxed{5} ).
