How do you use chemical nomenclature?

How do you use chemical nomenclature? The name of the metal is written first, followed by the name of the nonmetal with its ending changed to –ide. For example, K2O is called potassium oxide. If the metal can form ions with different charges, a Roman numeral in parentheses follows the name of the metal to […]

How do we calculate tension?

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 […]

What are the dimensions of the quantity?

What are the dimensions of the quantity? The dimension of a physical quantity is defined as the powers to which the fundamental quantities are raised in order to represent that quantity. The seven fundamental quantities are enclosed in square brackets [ ] to represent its dimensions. What are the dimensions of the quantity 1? The […]

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 […]

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 […]

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 […]
