Is radioactive decay first order?
Is radioactive decay first order? Because radioactive decay is a first-order process, the time required for half of the nuclei in any sample of a radioactive isotope to decay is a constant, called the half-life of the isotope. Radioactive decay is a first-order process. What is the formula of activity? To find the activity R […]

What is the photoelectric effect and how did Einstein explain it?
What is the photoelectric effect and how did Einstein explain it? In 1905 Einstein extended Planck’s hypothesis to explain the photoelectric effect, which is the emission of electrons by a metal surface when it is irradiated by light or more-energetic photons. What did Einstein theorize in the photoelectric effect? Since light is bundled up into […]

How does a hurricane finally die down?
How does a hurricane finally die down? Explanation: One of the driving forces of a hurricane is heat energy in oceanic surface waters. Warm water evaporates more quickly, and warm air rises. If it moves onto land it loses that warm water source, and so dies down. What eventually stops a hurricane? The End of […]
