high-voltage power lines I am Ricardo Bressan and you are very welcome to Megafatos And in today's video we've separated some curious questions that you didn't know the answer to until Watch this video Then go ahead and give that big like subscribe to the channel and turn on the notification bell Ready for the video How are ships placed in the sea After the ships are built there are two ways to place them in the sea The first is less commonly used and is called the floating technique which consists of manufacturing The ship inside a dry dock that is a concrete hole that is below the sea When the ship is ready this dock is filled with water causing the ship to float The second and most commonly used method is called the launching technique which consists of placing the ship on an inclined ramp Steel cables pull the ship as it slides down the ramp and falls into the water When ships are launched into the sea it seems as if they will sink but thanks to the steel cables this does not happen Painkillers Recently a question from a Twitter user went viral on the internet The post was a very curious question How do painkillers know which part of the body is hurting The response that received the most likes was from that user who came up with a theory to explain the subject According to him when we take these medicines we always say where the pain is and thus the analgesic detects and acts on the spot It is obvious that this is not a plausible answer According to experts when we take a painkiller it ends up in the stomach and consequently enters the bloodstream Thus it can circulate throughout the body within minutes When a cell is injured it ends up releasing a substance called prostaglandin This substance is concentrated only in the area of pain and as the neurotransmitters These sensors in the environment are extremely sensitive to this substance so they end up sending signals to the brain that something is wrong Then as the painkiller circulates throughout the body it just needs to find the cells that are releasing that prostaglandin Thus the medication prevents the substance from continuing to be produced and the nerve cells They stop sending the pain information to the brain resulting in relaxation and pain relief That's how simple it is Orange ball If you travel by bus or car have you noticed that on almost all Brazilian highways Do they have some basketballs stuck on the high-voltage wires But after all what are these balls for First these balls are not basketballs and they are much larger than we imagine Glass fiber sphere

noticed but practically every bus Whether it is public or private transportation it has a red lever with the words Attention In case of emergency pull this lever But in an emergency would you know how to pull this lever We don't want this to happen to you but in case of an accident where the doors If the bus doors cannot be opened you must remain calm and remove the seal that protects the lever Then just pull the red lever down This will cause the bus window to loosen and allow you to exit the vehicle The snack is produced by Nestlé right Right I like milk and various drawings on its surface

and have a complexity and e perfection that no camera produced to date can approach So in the end if our eyes were cameras how many megapixels would they have According to several experts there is no
