What happens when an electron drops to a lower energy level? An electron can be excited when its absorbs energy from electromagnetic radiation. An excited electron can fall to a lower energy level. When this happens, energy is lost as electromagnetic radiation. Different changes in energy level cause the emission of different frequencies. What causes […]

What is unit step function and its Laplace transform?
What is unit step function and its Laplace transform? 1 into a systematic way to find the Laplace transform of a piecewise continuous function. It is convenient to introduce the unit step function, defined as. u(t)={0,t<01,t≥0. Thus, u(t) “steps” from the constant value 0 to the constant value 1 at t=0. If we replace t […]

How do heavier elements formed in stellar nucleosynthesis? Mar. 18, 2019 — Heavy elements are produced during stellar explosion or on the surfaces of neutron stars through the capture of hydrogen nuclei (protons). What is r in the r process? In nuclear astrophysics, the rapid neutron-capture process, also known as the r-process, is a set […]
What is the difference between chyme and bile?
What is the difference between chyme and bile? Chyme is different from bile because chyme is actually mixed with bile to lower its pH.
