What is the temperature of bitumen? They range from -2 C to 21 C from Kashmir to Kanya Kumari. Viscosity graded VG-30 bitumen is suitable down to -10 C (due to its controlled temperature susceptibility). At temperatures lower than -10 C we can use softer grades such as VG-20 and VG-10. What do you mean […]

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 […]

What is the main reason for melting of ice sheets? Human activities are at the root of this phenomenon. Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on […]

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 four key ideas of psychoanalytic theory? Psychoanalytic theory is based on a small number of key ideas, including psychic determinism, the mind’s three-part internal structure (id, ego, and superego), psychic conflict, and mental energy….. What does the psychoanalytic theory focus on? Psychoanalytic theory focuses on the role of a person’s unconscious, as […]

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 […]
