What does the law of conservation verify? The law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it’s added from the outside. What is the equation for […]
What are the three main causes of uneven warming of the earth?
What are the three main causes of uneven warming of the earth? Unequal heating of Earth, atmospheric convection currents, rotation of the earth, Coriolis effect, earth’s orbit on a tilted axis, and the circulation of ocean waters at the surface and deep ocean. What happens to the air pressure as you move from the troposphere […]
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 most important difference between the Schachter singer two-factor theory of emotion and the James Lange theory of emotion?
What is the most important difference between the Schachter singer two-factor theory of emotion and the James Lange theory of emotion? The Cannon-Bard theory proposes that emotions and arousal occur at the same time. The James-Lange theory proposes the emotion is the result of arousal. Schachter and Singer’s two-factor model proposes that arousal and cognition […]

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 […]
