Diesel-Electric submarines use diesel fuel to run their diesel-generators, which provide power to charge their batteries for submerged operations. Nuclear-powered boats typically use a uranium core with a pressurized water configuration. The Russians have also experimented with liquid metal rather than water (bismuth).
Submarine weights can vary significantly depending on their type and size. A typical military submarine can weigh anywhere from 1,500 tons for smaller, smaller-class submarines to over 18,000 tons for larger, nuclear-powered submarines. For example, the U.S. Navy's Virginia-class submarines weigh approximately 7,800 tons, while the Ohio-class ballistic missile submarines can weigh around 18,750 tons when submerged.
Bike lights can be powered by multiple forms of power. The most common type of light is battery powered and that is easiest to install. Another type of bike light is solar powered during the day and shows light at night.
As of now, the only African countries known to possess submarines are Egypt and Algeria. Egypt has several submarines, including German-made Type 209 submarines, while Algeria operates a fleet of Russian-made Kilo-class submarines. These countries have invested in submarine capabilities to enhance their naval power and security. Other African nations do not have operational submarines at this time.
Submarines can stay underwater for extended periods, often ranging from several days to weeks, depending on their type and technology. Nuclear-powered submarines can remain submerged for months at a time, limited primarily by food supplies and crew endurance. Conventional diesel-electric submarines typically have shorter underwater endurance, often around a week, due to the need to surface for air or recharge batteries. Advances in technology continue to enhance the underwater capabilities of submarines.
The weight of an average submarine can vary significantly depending on its type and purpose. A typical military submarine can weigh anywhere from 1,500 tons for smaller, diesel-electric submarines to over 18,000 tons for larger nuclear-powered submarines. For example, the U.S. Navy's Virginia-class submarines weigh around 7,800 tons. In contrast, smaller research or tourist submarines can weigh as little as a few tons.

Nuclear energy is not gathered or created. There is a saying to go along with this: Energy cannot be created or destroyed, only changed in form. That saying is called the Law of the Conservation of Energy. Nuclear is a type of potential energy so this concept applies to it. There are many ways nuclear energy can be used. Lets say submarines. Most people have heard of the nuclear powered submarines. They can stay under water for a long time because they have basically unlimited energy. The submarines are powered by a nuclear reactor causing a series of nuclear reactions. The submarine uses the nuclear reactions as power. Generally it will get converted to mechanical or electrical energy (both types of Kinetic energy).
Most common are oil-powered thermal power stations; there are also some coal-powered and nuclear-powered stations (Mexico has two nuclear reactors worth 1.4 GW). There are also geothermal power plants and hydroelectric plants. Wind and solar power are growing in importance, but are still uncommon.
medieval millitary used horses and different armor as for todays armory uses high powered guns and a new type of gear and have hellicopyors to drop bombs bombs with.
The weight of a submarine varies significantly based on its type and purpose. A small research submarine might weigh around 100 tons, while larger military submarines, such as nuclear-powered ones, can weigh over 10,000 tons when submerged. The heaviest submarines, like the Russian Typhoon class, can exceed 24,000 tons. Overall, submarines are designed to be heavy enough to submerge and navigate underwater effectively.
