As you may have already seen, light sometimes behaves as a wave and sometimes as a particle. This is due to something we call "wave-particle duality" by which we mean that objects on the quantum...

First we recall the general formula for the volume of revolution: V = π ∫ [f(x)]² dx Substituting our function, this gives: V = π ∫₀¹ (3^x)² x dx We could write (3^x)² as 3^(2x), or we could notice that t...

Yes (beneficial):

-Increase in GDP, increase in disposable income, increase in standard of living, increase in consumption, increase in AD --> multiplier effect

Warm and distill with acidified pottasium dichromate. Then test with tollens reagent. The acidified pottasium dichromate will have oxidised the primary alcohol to an aldehyde, which will form a silver mir...

By defintion, Le chatelier's principle states that if a reaction at equilibrium (i.e a reversible reaction) is subject to a change in concentration, pressure or temperature the system will act in a way to...
