What is the main idea behind magnetic anomaly detectors? A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth’s magnetic field. What did marine magnetic anomalies prove? These anomalies provided the convincing evidence for plate tectonics and the resulting revolution in the earth sciences. In addition to the intensity […]
What is the frequency of a photon of light with an energy of 3 eV?
What is total internal reflection simple definition?
What is total internal reflection simple definition? Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle. What […]
Which feature of a heating curve indicates a change of state?
Which feature of a heating curve indicates a change of state? The diagonal or the inclined lines shows the changes in terms of temperature, and the horizontal lines shows the changing of phases. What do you understand by change of state give two examples of change of state? The physical process where matter moves from […]

What did Harry Harlow find when he gave monkeys raised in isolation the choice of cloth covered or wire substitute mothers?
What did Harry Harlow find when he gave monkeys raised in isolation the choice of cloth covered or wire substitute mothers? In both conditions, Harlow found that the infant monkeys spent significantly more time with the terry cloth mother than they did with the wire mother. When only the wire mother had food, the babies […]
What characteristics best describes what happens during a physical change?
What characteristics best describes what happens during a physical change? A physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density. What best describes the type of physical change […]
Is carbon dioxide bad in drinks?
Is carbon dioxide bad in drinks? “While soda and other carbonated drinks have been associated with negative health effects, carbonation is not harmful in and of itself,” says Saima Lodhi, MD, an internal medicine doctor at Scripps Coastal Medical Center Hillcrest. Drinking plain carbonated water has some health benefits, she adds. What happens when the […]
