What is a proton and its function? Function in the Atom The protons inside an atom’s nucleus help bind the nucleus together. They also attract the negatively charged electrons, and keep them in orbit around the nucleus. The number of protons in an atom’s nucleus determines which chemical element it is. Is proton a positive […]
Does black body actually exist?
Does black body actually exist? Although a blackbody does not really exist, we will consider the planets and stars (including the earth and the sun) as blackbodies. According to the above definition, a blackbody will emit radiation in all parts of the EM spectrum, but by intuition, we know that one will not radiate in […]
What does not affect potential energy?
What does not affect potential energy? so it is independent of the speed of object. So speed of object will not affect the gravitational potential energy. What has the least potential energy? plasma state What is another name for potential energy? What is another word for potential energy? chemical potential energy electric potential energy electrostatic […]
How do physical and social changes affect your life as an adolescent?
How do physical and social changes affect your life as an adolescent? During adolescence, you’ll notice changes in the way your child interacts with family, friends and peers. Every teen’s social and emotional development is different. Social changes and emotional changes show that your child is forming an independent identity and learning to be an […]
Does critical angle depend on?
Does critical angle depend on? (a) The critical angle of a medium depends upon the refractive index, wavelength of light and the temperature of the medium. Does critical angle depend on frequency? Yes, it depends. Does critical angle depend on wavelength used? Critical angle depends on the refractive index of a material, which in turn […]
Why does NASA launch rockets from Florida?
Why does NASA launch rockets from Florida? It was selected for two reasons: the fact that it is relatively near to the equator compared with other U.S. locations; and the fact that it is on the East Coast. An East Coast location was desirable because any rockets leaving Earth’s surface and traveling eastward get a […]
How do plants absorb photons of light energy?
How do plants absorb photons of light energy? When a plant is exposed to light, photons of appropriate wavelength will strike and be absorbed by the pigment-protein complexes arrayed on the thylakoid membranes. When this happens, the energy of the photon is transferred to the pigment molecule, thus causing the pigment to go into an […]
What is the phase of the wave?
What is the phase of the wave? Wave phase is the offset of a wave from a given point. When two waves cross paths, they either cancel each other out or compliment each other, depending on their phase. These effects are called constructive and destructive. The word phase is used to describe a specific location […]
How does environment affect natural selection?
How does environment affect natural selection? Explanation: In a population, the natural selection will favour the individuals with the higher fitness (In other words : the ones which have the best chances to survive and reproduce) in a given environment. It means that, for different environment, one gene can give different trait values at the […]
What are the two basic principle of electromagnetism?
What are the two basic principle of electromagnetism? Electromagnetic survey methods are based on two fundamental principles: Faraday’s law of electromagnetic induction and the fact that electric currents generate magnetic fields, expressed in Ampère’s law. What are the properties of magnetism? Magnets exhibit the following properties: All magnets have two poles: the North Pole and […]
