Is the changing of liquid water to water vapor? Evaporation – Evaporation happens when heat from the Sun turns liquid water into water vapor (gas). About 90% of the water in the atmosphere comes from evaporation. Most evaporation occurs in the oceans, because they cover so much of Earth’s surface. Why do we see droplets […]
Is fog caused by temperature inversion?
Is fog caused by temperature inversion? Sound is affected during fog conditions due to the small distances between water droplets, and air temperature differences. Temperature effect: A fog can be caused by a temperature inversion where cold air is pooled at the surface which helped to create the fog, while warmer air sits above it. […]
Why do insects not die from falling?
Why do insects not die from falling? So the resistance to falling in the case of the small animal is relatively ten times greater than the driving force. An insect, therefore, is not afraid of gravity; it can fall without danger, and can cling to the ceiling with remarkably little trouble. Is it OK to […]
What is the correct order for the three steps in signal transduction?
What is the correct order for the three steps in signal transduction? In effect, signal transduction is said to have three stages: First, reception, whereby the signal molecule binds the receptor. Then, signal transduction, which is where the chemical signal results in a series of enzyme activations. Finally, the response, which is the resulting cellular […]
What stimulates sensory receptors?
What stimulates sensory receptors? Sensory receptors in the oral region and respiratory system generally are excited by chemical or mechanical stimulation. Taste, of course, is based on chemical stimulation. Mechanicoreceptors respond when stimuli distort them. What three receptors are associated with touch? There are three main groups of receptors in our skin: mechanoreceptors, responding to […]
What is the function of vacuum tube?
What is the function of vacuum tube? A vacuum tube, an electron tube, valve (British usage) or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. Who invented triode tube? John Ambrose Fleming What is the difference between […]
When two electrons have the same spin in the same orbital which principle is being violated?
When two electrons have the same spin in the same orbital which principle is being violated? Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) […]
What occurs after condensation?
What occurs after condensation? After Water Condenses Some of the water vapor in the atmosphere that condenses is stored in clouds. Clouds are more likely to form when the air is humid and contains more water vapor. The energy released when gaseous water vapor condenses to form liquid water droplets is called latent heat. What […]
What happens if a satellite is moving too fast enough to stay in orbit?
What happens if a satellite is moving too fast enough to stay in orbit? If the satellite is thrown out too fast it will escape from the Earth’s orbit because the gravitational pull is not sufficient to provide the required centripetal force. With the correct launch speed the satellite continues in its falling orbit around […]
What is the SI unit of centripetal acceleration?
What is the SI unit of centripetal acceleration? The unit of centripetal acceleration is m/s2. What is called centripetal acceleration? Centripetal acceleration is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity and has the magnitude. The unit of centripetal acceleration […]
