Is needed to start a chemical reaction?
Is needed to start a chemical reaction? Chemical reactions won’t begin until the reactants have enough energy. The energy is used to break the chemical bonds of the reactants. Then the atoms form the new bonds of the products. Activation Energy is the minimum amount of energy needed to start a chemical reaction. What 3 […]
What are the two types of kinetic friction?
What are the two types of kinetic friction? In general, the friction is of the following two types: (1) Static friction. It is the friction, experienced by a body, when at rest. (2) Dynamic friction. It is the friction, experienced by a body, when in motion. (a) Sliding friction. (b) Rolling friction. (c) Pivot friction. […]

How can I represent relationships between two variables?
How can I represent relationships between two variables? Correlation Correlation analysis seeks to identify (by a single number) the degree to which there is a (linear) relation between the numbers in sets of data pairs. Regression analysis is used to determine if a relationship exists between two variables. 1)Generation of the regression line and equation […]
