What are the origin of the universe?
What are the origin of the universe? The best-supported theory of our universe’s origin centers on an event known as the big bang. This theory was born of the observation that other galaxies are moving away from our own at great speed in all directions, as if they had all been propelled by an ancient […]
What type of bond is potassium sulfur?
What type of bond is potassium sulfur? ionic bond What is the bond between potassium and sulfur? The difference in charge between the two 1+ potassium ions and the 2- sulfur ion allows electrostatic attraction between the sulfur ions and potassium ions. This is an ionic bond and is the basis of the ionic compound […]

Why can psychology be considered a science?
Why can psychology be considered a science? Psychology is a science because it follows the empirical method. The scientific status of any endeavor is determined by its method of investigation, not what it studies, or when the research was done, and certainly not by who did the investigation. All sciences use the empirical method. What […]
What is the difference between SAR and radar?
What is the difference between SAR and radar? SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional beam-scanning radars. Additionally, SAR has the property of having larger apertures for more distant objects, allowing consistent spatial resolution over a range of viewing distances. What is the […]
What will possibly happen when rocks bend without breaking?
What will possibly happen when rocks bend without breaking? If rocks tend to bend without breaking, they are said to be ductile. If a rock bends but is able to return to its original position when the stress is released, it is said to undergo elastic behavior. Earthquakes and faults occur in the shallow crust, […]
What was early Autotroph called?
What was early Autotroph called? Photoautotrophs What is an example of an Autotroph? Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis. Why are humans referred […]

How do I make sure everyone has clean water? 5 ways to improve water quality and access to water Improve sanitation facilities by providing toilets and latrines that flush into a sewer or safe enclosure. Promote good hygiene habits through education. Implement rainwater harvesting systems to collect and store rainwater for drinking or recharging underground […]
What is radius of curvature in light?
What is radius of curvature in light? Radius of curvature (ROC) has specific meaning and sign convention in optical design. A spherical lens or mirror surface has a center of curvature located either along or decentered from the system local optical axis. The distance from the vertex to the center of curvature is the radius […]
