[J2] Lesson 33 (SHM Grade A Questions + Normal + Sampling Distribution + Solubility Equilibrium 2)

[J2 Physics PMCians] Simple Harmonic Motion (Grade A)


What we did in 2 hours:

This week, we reviewed Structured Questions on Simple Harmonic Motion, with emphasis on springs mass systems in vertical oscillations

What you take home:

SHM Grade A Test 0 (solutions)

For your reference only.  



SHM Grade A Test 2 (solutions)  

For your reference only.


Special Mention:

In our next lesson, we start our Grade A revision on Waves & Superposition, a section not to be missed!

Till we meet again, have a safe and peaceful week ahead!


From you friendly tutors,

What we did in 2 hours:

Finishing our last examples on Binomial Distribution, we moved on to Normal Distributions. The questions are getting tedious, do note how we focus on simplifying the context into workable parts and being ready to deal with concepts from other chapters.

What you take home:

Worked solutions for Q2 and Daily Dose are linked here:



Weekly Quiz: Quiz F and Solutions for Quiz E have been updated into the link.


Special Mention:

We will complete our Normal and Sampling Distributions this week.


See You and Stay Healthy!

What we did in 2 hours:

This lesson, we looked at the tough (and tricky) questions of Solubility Equilibrium, paying much attention to the toughest part of the chapter – Selective Precipitation. We moved on to discuss harder questions in Redox Reactions.

What you take home:

The solutions to Homework to Acidity, Basicity, Hydrolysis of Organic Compounds and Amino Acids & Proteins, and Q12 of Solubility Equilibrium are found here:
