How fast can a pig eat a human body? the faster it goes. “You need at least sixteen pigs to finish the job in one sitting, so be wary of any man who keeps a pig farm. They will go through a body that weighs 200 pounds in about eight minutes. That means that a […]

What happens in a tug of war when two teams pull equally hard? If the two forces act in the opposite directions on an object, the net force acting on it is the difference between the two forces. Recall that in the tug-of-war when two teams pull equally hard, the rope does not move in […]

How many valence electrons does group 16 have? 6 What do valence electrons represent? Valence electrons, then, are electrons in the outermost shell of the atom that determine an atom’s or group’s ability to bond with others. In chemistry, a group refers to two or more atoms that are specifically arranged. What are valence electrons […]

What do you call loss of traction? Fishtailing is a vehicle handling problem which occurs when the rear wheels lose traction, resulting in oversteer. This can be caused by low friction surfaces (sand, gravel, rain, snow, ice, etc.). This causes a lot of friction, even if the tires are allowed to rotate freely. Which way […]

Why did my string lights stop working? The problem may also be a bad fuse. Most string lights have two tiny fuses inside the plug. Typically, a box of lights is also packaged with a replacement fuse or two. Then gently pop out the fuse and replace it with new ones. What happens to the […]

What type of air mass is most likely to form a thunderstorm? Air mass thunderstorms tend to occur within a maritime tropical air mass. The wind shear is weak and this is why the air mass storms are not severe, do not last long and do not move quickly. The main threats from an air […]

What happens if you move the fulcrum? Students discover that when the fulcrum is between the load and the effort (first class lever), moving the fulcrum closer to the load increases the length of the effort arm and decreases the length of the load arm. Is Archimedes a hero? He gained a lot of knowledge […]

How much do particles weigh? Hence a particle of “approximate mass” 1 in the table would weigh about 3.67 x 10 -27 pounds….Well-known Particles. Code Name Approximate mass Charge 2C 5 2 3A 5 3 What is the mass of the dust grain in kg ]? SOLUTION: The mass of a dust particle is 7.53 […]

What is the heating effect of current? When an electric current passes through a conductor (like a high resistance wire) the conductor becomes hot after some time and produces heat. This is called heating effect of Electric Current. Example 1. A bulb becomes hot after its use for some time. Why does current produce heat? […]

What is the most common type of chemical bonding in minerals? Most minerals are characterized by ionic bonds, covalent bonds, or a combination of the two, but there are other types of bonds that are important in minerals, including metallic bonds and weaker electrostatic forces (hydrogen or Van der Waals bonds). What are the two […]
