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. **

To keep wood submerged in the aquarium, you can try soaking the wood in water for a few days before placing it in the tank. This will saturate the wood and make it heavier, helping it to stay submerged. Additionally, you can attach a weight to the wood using aquarium-safe materials like suction cups or fishing line to keep it from floating to the top. Lastly, positioning the wood in a way that it is partially buried in the substrate can also help keep it in place. **

To keep wood submerged in an aquarium, you can try soaking the wood in water for a few days before placing it in the tank. This will saturate the wood and make it heavier, helping it stay submerged. Additionally, you can attach a weight to the wood or use aquarium-safe silicone to secure it to a rock or other heavy object at the bottom of the tank. Lastly, make sure the wood is fully waterlogged before placing it in the aquarium to prevent it from floating to the top. **

To keep wood submerged in the aquarium, you can try soaking the wood in water for a few days before placing it in the tank. This will saturate the wood and make it less buoyant. Additionally, you can attach a weight to the wood using aquarium-safe materials like suction cups or fishing line to help keep it at the bottom of the tank. Another option is to use rocks or other heavy decorations to weigh down the wood and prevent it from floating to the top. **

Diving goggles are not allowed in the swimming pool because they are designed for use in deep water and can obstruct peripheral vision, increasing the risk of collisions with other swimmers. Additionally, diving goggles are not necessary for swimming laps or recreational swimming in a pool with clear water. The use of diving goggles in a swimming pool can also create a safety hazard if the wearer dives into shallow water thinking it is deeper than it actually is. **

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. **

When an ice piece floats in a liquid, it displaces its own weight of the liquid. Since ice has a density of about 0.92 g/cm³, it will displace a volume of liquid equal to its own weight, which is the same as its own volume. Therefore, the volume fraction of the ice piece submerged when it floats in a liquid with a density of 1.12 g/cm³ is 0.92/1.12, which is approximately 0.82 or 82%. **
