How do we calculate tension? Tension Formulas – How to Calculate Tension Force Tension can be easily explained in the case of bodies hung from chain, cable, string etc. T = W ± ma. Case (iv) If the body moves up or down with uniform speed, tension; T = W. T=m(g±a) As tension is a […]
How do astronomers detect dark matter?
How do astronomers detect dark matter? Galaxy clusters are particularly important for dark matter studies since their masses can be estimated in three independent ways: From the scatter in radial velocities of the galaxies within clusters. From X-rays emitted by hot gas in the clusters. Is dark matter invisible? Scientists have not yet observed dark […]
What kind of variable is behavior?
What kind of variable is behavior? An ordinal variable is a categorical variable for which the possible categories can be placed in a specific order or in some ‘natural’ way. In Table 2, the variable ‘behaviour’ is ordinal because the category ‘Excellent’ is better than the category ‘Very good’, etc. Which of the following is […]
How does a fan convert energy?
How does a fan convert energy? (The fan’s blades move air around the room. The kinetic energy of the moving blades does work in moving air through the fan blades.) The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.) What does a fan do to […]
When electric field is applied on the ends of a conductor the free electrons start moving in direction?
When electric field is applied on the ends of a conductor the free electrons start moving in direction? These free electrons inside the conductor move randomly and frequently collide with heavier atoms and change their direction of motion every time. When a steady electric field is applied to the conductor, the electrons start moving towards […]
What are the embryological evidence that we all have a common ancestry?
What are the embryological evidence that we all have a common ancestry? They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos. What is the evidence of embryology? The study of one type of evidence of evolution […]
Which is called the living part of a cell?
Which is called the living part of a cell? Protoplasm (/prəʊtə(ʊ)ˌplaz(ə)m/, plural protoplasms) is the living part of a cell that is surrounded by a plasma membrane. In some definitions, it is a general term for the cytoplasm (e.g., Mohl, 1846), but for others, it also includes the nucleoplasm (e.g., Strasburger, 1882). Is a living […]
What are ionic compounds formed by?
What are ionic compounds formed by? Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond […]
What is Mew M?
What is Mew M? The micrometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is an SI derived unit of length equalling 1×10−6 metre (SI standard prefix “micro-” = 10−6); that is, one millionth of a metre (or […]
What is the main goal of Gestalt therapy?
What is the main goal of Gestalt therapy? Gestalt therapy seeks to resolve the conflicts and ambiguities that result from the failure to integrate features of the personality. The goal of Gestalt therapy is to teach people to become aware of significant sensations within themselves and their environment so that they respond fully and reasonably […]
