Submerged submarines can be located using a variety of methods, including sonar technology, which uses sound waves to detect underwater objects. Another method is through the use of magnetic anomaly detection (MAD) systems, which can detect the presence of a large metal object like a submarine. Additionally, some submarines can be located using passive acoustic detection, which involves listening for the sounds emitted by the submarine's machinery or propellers. Finally, advanced satellite and aerial surveillance technologies can also be used to track the movements of submarines. **

The length of time a minor can stay submerged underwater varies depending on several factors such as age, physical condition, and water temperature. On average, a healthy minor can hold their breath for around 30 seconds to 2 minutes. However, it is crucial to always supervise minors when they are in or around water to prevent any accidents or drowning incidents. **

No, the Ninjago Water Strider is not designed to be submerged in water. While it is a watercraft that can float on water and move across its surface, it is not intended to be fully submerged. Submerging it in water could damage its electronic components and affect its functionality. It is best to use the Water Strider as intended, on the surface of water. **

Contemporary plays can be considered modern in the sense that they reflect current societal issues, values, and cultural norms. They often incorporate modern technology, language, and themes that are relevant to today's audience. However, the term "modern" can also refer to a specific historical period in theater, typically the late 19th and early 20th centuries, so in that sense, contemporary plays may not be considered modern. Overall, the classification of contemporary plays as modern depends on the context and definition being used. **

Babies are born with a reflex called the "dive reflex" or "bradycardic response," which is triggered when they are submerged in water. This reflex causes their heart rate to slow down and blood flow to be redirected to vital organs, allowing them to conserve oxygen. Additionally, their vocal cords close to prevent water from entering their lungs. These physiological responses help babies to survive underwater for a short period of time without breathing. However, it is important to note that babies should never be submerged in water without close supervision, as they are still at risk of drowning. **

Yes, the Brita water filter should always be submerged in water when in use. Submerging the filter allows water to flow through the filter media, which removes impurities and improves the taste of the water. If the filter is not submerged, it will not be able to effectively filter the water, and the quality of the filtered water will be compromised. Therefore, it is important to always ensure that the Brita water filter is fully submerged in water when in use. **

Yes, in many Christian denominations, a person is completely submerged in water during baptism. This form of baptism is known as immersion, and it symbolizes the washing away of sins and the resurrection to new life. However, some denominations practice baptism by pouring or sprinkling water over the person's head, which is known as affusion. Both forms of baptism are considered valid by different Christian traditions. **

The aquarium heater should be fully submerged in the water to ensure proper and even distribution of heat throughout the tank. It is important to follow the manufacturer's instructions regarding the minimum water level required for the heater to function effectively. Typically, the water level should be at least at the same level as the minimum water line indicated on the heater. Placing the heater deeper than necessary can cause overheating, while having it too shallow may lead to inaccurate temperature readings. **
