To determine the cable cross-section at 200A, we need to consider the current-carrying capacity of the cable. The cross-section of the cable will depend on the material of the cable, its insulation, and the ambient temperature. Typically, for a current of 200A, a cable with a cross-section of around 70-95mm² would be suitable. It is important to consult the manufacturer's specifications and local regulations to ensure the correct cable size is selected for the specific application. **

Yes, a wasp can lose its stinger. Unlike bees, wasps do not have barbed stingers, so they are able to sting multiple times without losing their stinger. However, if a wasp stings a human or animal, there is a chance that its stinger could break off and remain in the skin, causing the wasp to lose its stinger. Once a wasp loses its stinger, it will eventually die due to the damage caused to its abdomen. **

Not every stingray has a stinger. While most species of stingrays are equipped with a sharp, barbed stinger located at the base of their tail, there are some species that do not have a stinger at all. These stingrays are known as "stingless" or "whiptail" stingrays. Instead of a stinger, they have a long, whip-like tail that they use for defense. It's important to note that even stingrays without a stinger should be treated with caution and respect in their natural habitat. **

A long stinger, such as a wasp or hornet, flies by using its wings to generate lift and propel itself through the air. These insects have powerful flight muscles that allow them to move quickly and maneuver with precision. They can adjust the angle of their wings and the frequency of their wing beats to control their speed and direction while flying. Additionally, their streamlined bodies and aerodynamic shape help reduce air resistance, enabling them to fly efficiently. **

Yes, wasps do sting with their stinger. When a wasp feels threatened or is provoked, it will use its stinger to inject venom into its target. This can cause pain, swelling, and in some cases, allergic reactions in humans. It's important to be cautious around wasps and to avoid provoking them in order to prevent getting stung. **

The insect with a long stinger is the female of the species of wasps, particularly the tarantula hawk wasp. The female tarantula hawk wasp has a long stinger that she uses to paralyze tarantulas, which she then uses as a host for her eggs. This stinger is one of the longest in the insect world and is used as a defense mechanism and for hunting. **

Yes, a queen wasp does have a stinger. The stinger is a modified egg-laying organ called an ovipositor, which can also be used for defense. Queen wasps use their stingers primarily for defending themselves and their nests. Unlike worker wasps, queen wasps can sting multiple times without dying because their stingers are not barbed. **

The honeybee is an insect that loses its stinger when it stings. When a honeybee stings, its stinger gets stuck in the victim's skin, causing the bee to die shortly after. This is because the stinger is attached to the bee's internal organs, and when it detaches, it causes fatal injuries to the bee. Other insects, like wasps and hornets, can sting multiple times without losing their stingers. **
