What is the formula of electric force? Calculate the electrostatic force using the formula: F = K[q1 x q2]/D^2 where K is coulombs constant, which is equal to 9 x 10^9 Nm^2/C^2. The unit for K is newtons square meters per square coulombs. What is an example of repulsive force? For example, the force between […]
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 […]
Which statement best describes the relationship between science and technology?
Which statement best describes the relationship between science and technology? The goal of science is to create solutions that improve people’s lives by mimicking the natural world, while the goal of technology is to build machines. Which statement best describes how an existing theory is often affected by the development of new technology quizlet? Which […]
What is a proton and its function?
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 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 […]
What are the three main pathways of ATP production?
What are the three main pathways of ATP production? In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes—glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation—to produce ATP. What is the ATP CP system? The ATP-PC system uses a stored molecule in […]
Why is only 10 of energy passed on?
Which is more stronger in bending equal area square or circular beam?
Which is more stronger in bending equal area square or circular beam? Two beams of equal cross-sectional area are subjected to equal bending moment. If one beam has square cross-section and the other has circular section, then. Both beams will be equally strong. Circular section beam will be stronger. What is the strongest cross section […]
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 […]
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 […]
