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 is difference between paramagnetic and diamagnetic?
What is difference between paramagnetic and diamagnetic? Atoms with all diamagnetic electrons are called diamagnetic atoms. A paramagnetic electron is an unpaired electron. Diamagnetic atoms repel magnetic fields. The unpaired electrons of paramagnetic atoms realign in response to external magnetic fields and are therefore attracted. Why zinc is diamagnetic? Answer. Answer: Diamagnetic means the orbitals […]
Is hydrogen peroxide supposed to foam?
Is hydrogen peroxide supposed to foam? Hydrogen peroxide does not foam in the bottle or on your skin because there is no catalase to help the reaction to occur. Hydrogen peroxide is stable at room temperature. What is the changing of liquid to a gas called? At a certain temperature, the particles in a liquid […]
Is normal force a centripetal force?
Is normal force a centripetal force? The normal force and a component of the weight point toward the center of the loop (the component perpendicular to the loop), so they get to be the centripetal force. How is centripetal force calculated? Centripetal force is measured in Newtons and is calculated as the mass (in kg), […]
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 is another word for isotope?
What is another word for isotope? What is another word for isotope? element form variant version What is the correct statement about isotopes? Isotopes of only heavier elements are radioactive in nature as they have large difference in the number of protons and neutrons. Thus, we can conclude that the statement isotopes of the same […]
Is Bangladesh in Pakistan or India?
Is Bangladesh in Pakistan or India? Pakistan and Bangladesh are two separate and independent countries physically divided by India. Historically, this was not always the case: from 1947 to 1971 they were administered under the same government. The two countries share a number of attributes. How are rivers important to the peoples of Pakistan and […]
Why do electrons do not fall in nucleus?
Why do electrons do not fall in nucleus? Quantum mechanics states that among all the possible energy levels an electron can sit in the presence of a nucleus, there is one, which has THE MINIMAL energy. This energy level is called the ground state. So, even if atoms are in a very very called environment, […]
Why does a rocket keep accelerating?
Why does a rocket keep accelerating? As the rocket velocity increases, it encounters air resistance, or aerodynamic drag, which opposes the motion. Drag increases as the square of the velocity. The thrust of the rocket must be greater than the weight plus the drag for the rocket to continue accelerating. Do Newton’s laws apply in […]
