How do you know if paramagnetic or diamagnetic? Whenever two electrons are paired together in an orbital, or their total spin is 0, they are diamagnetic electrons. Atoms with all diamagnetic electrons are called diamagnetic atoms. A paramagnetic electron is an unpaired electron. An atom is considered paramagnetic if even one orbital has a net […]
Why do electrons move between energy levels?
Why do electrons move between energy levels? As Neils Bohr showed, it is possible for electrons to move between energy levels. Light contains energy. The electron with its extra packet of energy becomes excited, and promptly moves out of its lower energy level and takes up a position in a higher energy level. Why does […]
What is a device that changes sound into an electrical signal?
What is a device that changes sound into an electrical signal? Electromechanical transducer, any type of device that either converts an electrical signal into sound waves (as in a loudspeaker) or converts a sound wave into an electrical signal (as in the microphone). What is a transducer that converts electrical energy to light called? Photoelectric […]
How do you calculate work input?
How do you calculate work input? Calculate the work input in a pulley by using the previous readings in the correct mathematical equation: Work (W) equals force (f) multiplied by distance (d), or W=fd. The work done by the pulley is the equation of weight (w) multiplied by height traveled (h). How do you calculate […]
How many days do fireflies live?
How many days do fireflies live? Fireflies only live a couple of weeks as adults. But, accounting for each stage of development from egg to adult, fireflies typically live for about a year. Throughout that time, they are only capable of flying and laying eggs for approximately two months. Will fireflies light up in a […]
What is the relationship between brightness and temperature star?
What is the relationship between brightness and temperature star? The Luminosity of a star depends on BOTH its temperature and its radius (surface area): L is proportional to R2 T4. A hotter star is more luminous than a cooler one of the same radius. A bigger star is more luminous than a smaller one of […]
Which of the following is correct order of forces?
Which of the following is correct order of forces? Weak < gravitational < electrostatic < strong forces. How many fundamental forces exist in nature? four fundamental forces Is there a fifth force of nature? All of the forces we experience every day can be reduced to just four categories: gravity, electromagnetism, the strong force and […]
Is it best to keep doors shut when heating is on?
What are the two major types of planets?
What are the two major types of planets? Planets are generally divided into two groups: the terrestrial and the giant planets. The terrestrial planets are the four inner planets: Mercury, Venus, Earth, and Mars. They are generally small in size (about the size of the Earth) and are predominantly rocky in composition. What are the […]
What is superconductor give example?
What is superconductor give example? A superconductor is a substance of zero resistance at a very low temperature. Example: Mercury at 4.2 K. Which type of materials are superconductors? Types of Superconductors Type-I Superconductor. Type-II Superconductor. Infinite Conductivity/ Zero Electric Resistance. Meissner Effect. Transition Temperature. Josephson Current. Critical Current. Persistent Currents. What are superconductors and […]
