What type of research is a descriptive study? Descriptive research is a type of research that describes a population, situation, or phenomenon that is being studied. It focuses on answering the how, what, when, and where questions If a research problem, rather than the why. What type of descriptive research study measures a population at […]
How do you know if alkene is symmetrical?
How do you know if alkene is symmetrical? A symmetrical alkene is an alkene in whose molecule the doubly bonded carbons bear the same ligands. eg. 1: In 1, each double bonded carbon bears two methyl groups. How do you identify asymmetric carbon? A carbon atom is asymmetric if it has four different chemical groups […]
What is the difference between indication and contraindication?
What is the difference between indication and contraindication? In medicine, a contraindication is a condition that serves as a reason to not take a certain medical treatment due to the harm that it would cause the patient. Contraindication is the opposite of indication, which is a reason to use a certain treatment. What are contraindications […]
What are the two basic types of speedometer?
What are the two basic types of speedometer? There are two types of speedometers: electronic and mechanical. Because the electronic speedometer is actually a relatively new invention — the first all-electronic speedometer didn’t appear until 1993 — this article will focus primarily on the mechanical speedometer, or the eddy-current speedometer. What do numbers symbolize on […]
Does acceleration due to gravity depend on mass?
Does acceleration due to gravity depend on mass? The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels, and thus the object’s weight, does. Why does mass resist acceleration? The more mass an object has the more weight it will have. Weight is caused by […]

Does anything have 100 efficiency?
Does anything have 100 efficiency? A system can never be 100% efficient. The reason behind this is because of heat and sound energy are lost in some amount in every system. No matter they are waste or not. So a system doesn’t exist, with 100% efficiency. Is human body energy efficient? Alas, our bodies are […]
Who invented inches?
Who invented inches? The old English ynce was defined by King David I of Scotland about 1150 as the breadth of a man’s thumb at the base of the nail. To help maintain consistency of the unit, the measure was usually achieved by adding the thumb breadth of three men—one small, one medium, and one […]

What are the 3 level of awareness? The three levels of awareness in human consciousness which are divided by Freud: the conscious, preconscious, and unconscious. Each of these levels interferes and overlaps with Freud’s ideas of the id, ego, and superego. What are 4 levels of consciousness? Take a look at the four levels of […]
What causes wave refraction?
What causes wave refraction? Refraction is the bending of a wave-front as it travels at different speeds over water of different depths. When different parts of the same wave-front travel at different speeds, the wave bends towards the slower part. The shallower the water, the slower the wave; therefore the wave bends towards the shallower […]
