How do metal leaf Electroscopes work?

How do metal leaf Electroscopes work? An electroscope is a device that detects static electricity by using thin metal or plastic leaves, which separate when charged. Electrical charges move to the metal and down to the foil leaves, which then repel each other. Since each leaf has the same charge (positive or negative), they repel […]

Is gold a ferromagnetic metal?

Is gold a ferromagnetic metal? Gold (Au) in its bulk form, like the metal in a wedding ring, is not considered a magnetic material. Technically, it is classified as “diamagnetic”, meaning that it can be repelled by a magnetic field, but cannot form a permanent magnet. Why Fe is ferromagnetic? The popular understanding of a […]

What are the 7 functions of the digestive system? Digestive System Physiology Ingestion of food. Secretion of fluids and digestive enzymes. Mixing and movement of food and wastes through the body. Digestion of food into smaller pieces. Absorption of nutrients. Excretion of wastes. What organs are part of the digestive system? The hollow organs that […]

What are two recently discovered state of matter?

What are two recently discovered state of matter? The two newly discovered states of matter are Plasma and Bose-Einstein Condensate. Does liquid glass exist? Glass, however, is actually neither a liquid—supercooled or otherwise—nor a solid. It is an amorphous solid—a state somewhere between those two states of matter. And yet glass’s liquidlike properties are not […]

What are the 5 points of Darwin natural selection?

What is quantum number explain with example?

What is quantum number explain with example? A quantum number is a value that is used when describing the energy levels available to atoms and molecules. An electron in an atom or ion has four quantum numbers to describe its state and yield solutions to the Schrödinger wave equation for the hydrogen atom. ms or […]

Why is liquid water important to life?

Why is liquid water important to life? Even organisms that live in very dry places need water to live. One reason that water is so important is because it’s a liquid. This means that it can move around the materials that are needed for chemical reactions. These reactions include the ability for cells to get […]

Como se puede medir la fuerza?

¿Cómo se puede medir la fuerza? La unidad de medida de fuerza es el newton que se representa con el símbolo: N, nombrada así en reconocimiento a Isaac Newton por su aportación a la física. El newton es una unidad derivada del SI que se define como la fuerza necesaria para proporcionar una aceleración de […]
