Express the coloumbs law and express it in vector form?

Answer»

Let there be TWO charges q1 and q2, with position vectors r1 and r2 RESPECTIVELY. Now, since both the charges are of the same sign, there will be a REPULSIVE force between them. Let the force on the q1 charge DUE to q2 be F12 and force on q2 charge due to q1 charge be F21. The corresponding VECTOR from q1 to q2 is r21 vector. r21 = r2 – r1 To denote the direction of a vector from position vector r1 to  r2 , and from r2 to r1 as: Now, the force on charge q2 due to q1, in vector form is: The above equation is the vector form of Coulomb’s Law.hope it helppls mark it as brainliest Explanation:

Answer»

The International Fisher Effect (IFE) states that the difference between the nominal interest rates. ... The International Fisher Effect is based on current and future nominal interest rates, and it is used to predict SPOT and future CURRENCY movements. The IFE is in contrast to other methods that use pure inflation.The Fisher Effect is an economic theory CREATED by economist Irving Fisher that describes the relationship between inflation and both real and nominal interest rates. The Fisher Effect states that the real interest rate equals the nominal interest rate minus the expected inflation rateThe Fisher Effect and the International Fisher Effect The IFE expands on the theory, suggesting that currency changes are proportionate to the difference between the two nations' nominal interest rates.

Distinguish among primary secondary and tertiary alcohol

Answer»

What is Secondary Alcohol?Secondary alcohols are the alcohols in which hydroxyl group is attached to the secondary carbon atom of the alcohol molecule. Secondary alcohols are CONVERTED into ketones (R2CO) upon oxidation under mild condition. Stronger oxidants, however, lead to the formation of acids or mixture of acids. With Lucas test, secondary alcohols form oily LAYERS within about five minutes. Secondary alcohols are more stable and more reactive than primary alcohols. However, secondary alcohols are less acidic than primary alcohols. Some examples of secondary alcohol include isopropyl alcohol and butyl alcohol.Figure 02: Secondary AlcoholDifference Between Primary and Secondary AlcoholDefinitionPrimary Alcohols: Primary alcohol is an alcohol which has the hydroxyl group connected to a primary carbon atom.Secondary Alcohols: Secondary alcohol is an alcohol which has the hydroxyl group on a secondary carbon atom.ReactivityPrimary Alcohols: Primary alcohols are less reactive than secondary alcohols.Secondary Alcohols: Secondary alcohols are more reactive than primary alcohols.EsterificationPrimary Alcohols: Rate of esterification is highest in primary alcohols.Secondary Alcohols: Rate of esterification is less in secondary alcohols.Easiness of DehydrationPrimary Alcohols: Primary alcohols are difficult to dehydrate than secondary alcohols.Secondary Alcohols: Secondary alcohols are easier to dehydrate.DehydrogenationPrimary Alcohols: Primary alcohols result in aldehydes and hydrogen.Secondary Alcohols: Secondary alcohols results in ketones and hydrogen.Lucas TestPrimary Alcohols: Primary alcohols do not form oily layers.Secondary Alcohols: Primary alcohols form oily layers within about five minutes.StabilityPrimary Alcohols: Primary alcohols are less stable than secondary alcohols.Secondary Alcohols: Secondary alcohols are more stable.VICTOR Meyer’s TestPrimary Alcohols:  Primary alcohols give a blood red color.Secondary Alcohols: Secondary alcohols give a blue color.AcidityPrimary Alcohols: Primary alcohols are more acidic than secondary alcohols.Secondary Alcohols: Secondary alcohols are less acidic.SummaryPrimary and secondary alcohols are two types of alcohols coming under monohydric alcohols. In primary alcohols, -C-OH group is attached one carbon atom, whereas, in secondary alcohols, -C-OH group is attached to another two carbon ATOMS. Based on this main difference between primary and secondary alcohols, their properties vary. Lucas test and Victor Meyer’s test are used to identifying primary and secondary alcohols.Reference:1.Johnson, A. W. (1999). INVITATION to organic chemistry. Jones & Bartlett Learning.2.Madan, G.
