What is SetRequest? The abstract class URLConnection is the superclass of all classes that represent a communications link between the application and a URL. Instances of this class can be used both to read from and to write to the resource referenced by the URL. What is SNMP protocol and how it works? SNMP works […]

How does the skin defend the body? The skin acts as an external barrier to bacteria, preventing infection and protecting the internal organs. The skin also protects the body from ultraviolet radiation using the pigment barrier formed from melanocyte cells found in the top of the papillary dermis and a protein layer found in the […]

What is moment and its SI unit? In physics, moment of force (often just moment) is a measure of its tendency to cause a body to rotate about a specific point or axis. The SI unit for moment is the newton meter (kgm²/s²). What is a force and state its SI unit? Answer Verified. Force […]

Can we create an artificial sun? For many years, scientists have tried to recreate nuclear fusion on Earth. Instead, the artificial suns being created today are nuclear fusion reactors. In 2017, the German Aerospace Center (DLR) announced its creation of such a device. This reactor is called Synlight and reaches temperatures of 5432 °F (3000 […]

How do you calculate the angle between the reflected ray and the normal? When a light ray hits a surface normally, the angle between the incident ray and the normal is 0, so Θi = 0. Since the angle of reflection equals the angle of incidence, Θr= 0. By Snell’s law, ni sin Θi = […]

What is KSP value? The solubility product constant, Ksp​, is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution. The more soluble a substance is, the higher the Ksp value it has. What is Q in KSP? The reaction quotient, Q, […]

What are the assumptions of the production possibility curve? The basic assumptions of production possibility curve are: The resources are given and remain constant. The technology used in the production process remains constant. The resources and technology are fully and efficiently utilized. The technique of production remains constant. What does point B represent? all of […]

What are idealized models? In physics, a model (or idealized model) is a simplified version of the physical system that strips away the unnecessary aspects of the situation. One thing that we don’t typically worry about is the physical size of the object, nor really it’s structure. What are models good for? Models use familiar […]

What is an example of homeostasis imbalance? A commonly seen example of homeostatic imbalance is diabetes. In a diabetic, the endocrine system has difficulty maintaining the correct blood glucose levels, so diabetics must closely monitor their blood glucose levels, as shown in Figure below. Which organ systems are the most important for maintaining homeostasis quizlet? […]

What process turns a gas into a liquid? When a gas changes into a liquid, it is called condensation. When a gas changes into a solid, it is called deposition . When a liquid changes into gas, it is called evaporation. Phase changes are usually caused by changes in temperature or pressure. What are the […]
