Why Marie Curie is a hero? She was a scientist that discovered two elements, polonium and radium, she also invented techniques for isolating radioactive isotopes. She also discovered radiation that could kill human cells. During World War 1 she was sent to work with French builders and she helped design the x-ray. What is a […]
What are the 3 classifications of carbohydrates?
What are the 3 classifications of carbohydrates? Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides. What are the classifications of carbohydrates? Carbohydrates are divided into four types: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides consist of a simple sugar; that is, they have the chemical formula C6H12O6. Disaccharides are two simple sugars. Which is […]
What happens when you wrap a wire around a nail?
What happens when you wrap a wire around a nail? By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the […]
Which plastic can be bent and remoulded repeatedly?
Which plastic can be bent and remoulded repeatedly? 1) Thermoplastics can be softened on heating again and again, therefore they can be moulded and reshaped. Thermosetting plastics cannot be softened on heating, therefore they cannot be moulded and reshaped. 2) Thermoplastics can be bent easily. Thermosetting plastics cannot be bent as they break when forced […]
What is tension and spring force?
What is tension and spring force? The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends. The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it. Is […]
What happens if you increase the frequency?
What happens if you increase the frequency? The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength […]
How many planets are habitable for humans?
How many planets are habitable for humans? Based on the findings, the Kepler team estimated there to be “at least 50 billion planets in the Milky Way” of which “at least 500 million” are in the habitable zone. How many planets are there in the universe and their names? There are eight planets in the […]
What is the loudest car in GTA?
What is the loudest car in GTA? My loudest is the Hotknife, Rat truck, or Trophy truck. The BEST sounding is my Carbonizzare. Halloween frankenstang is a loud one. Yeah agreed, the XA-21 sounds so awesome and has that amazing super car backfire that almost all the other cars are missing. Which Benny’s car is […]
What is the electrostatic attraction?
What is the electrostatic attraction? Electrostatic attraction refers to the electrostatic force of long-range interaction occurring between the attractive electrostatic adsorption in aqueous solution with differently charged particles or uncharged particles. What increases electrostatic attraction? The net attractive electrostatic attraction is increased as the nuclear charge increases. Electrons are being added to successive energy levels […]
