Try these: From Q 1. C, B, C, D, B, A, B, D, B, C, B, A, C, C, D, A, C, A, D, A.

As a motor coil spins in a magnetic field, it effectively is the same as a generator, that is a conductor coil cutting through magnetic field lines. Thus an emf is induced n the coils. Lenz law states that the direction of the induced current will be such as to create a magnetic field that...

Its a bit of a strange one cause according to the Board of Studies, Cells differentiate (that is they take on a specific structure relative to a particular tissue) then they specialise by switching on genes in order to perform a particular function for that designated cell type. In reality...

regarding Q2. (a) You need to calculate the molarity of the acetic acid in the original sample from the results of your titration (or supplied data) which is missing in your question, convert that to grams per mL and assess if it meets the standards. (b) With regards to the sulphuric acid...

I tutor Physics and can assure you both are C. Your reasoning in Q8 is correct, field lines run from + to neg. For Q 6. Again its C and Nightweaver has hit it on the button. Look at Fmagnetic = qvB which contributes to Fcentripetal = mv^2/r. Looking at your choices, increase in q or B...

Basically most questions require you to convert a mass to no of moles of a substance. Work out the Molar Mass by adding the elemental atomic masses found in the periodic table and apply the formula n = m/M where n = no of moles, m = mass of substance you have and M = molar mass. For ex: lets...
