# [J2] Lesson 36 (Gravitation A Questions + Statistic Consolidation + Periodic Table)

[J2 Physics PMCians] Gravitation (Grade A) Revision

What we did in 2 hours:

This week, we reviewed Grade A questions on Gravitation. Notably, we are prepared that this topic can be combined with other topics such as :

1) with Circular Motion – e.g Satellite questions, binary stars

2) with Conservation of Energy.

Binary Star – Gravitational Force provides Centripetal force to move in a circle

What we did in 2 hours:

Statistics Consolidation was plenty of fun wasn’t it! These recent questions from MYE and Prelims were chosen for the applied parts, which we noted to be mathematically straightforward, but tricky in setting up.

Do note how we break up the question into simpler parts based on keywords and focus on what the question is really asking for. Additionally, clues will always be given as to what type of distribution is being used (fixed total size? classified into yes/no?) and we will use that to our advantage!

What you take home:

Worked solutions for the final two questions are linked here:

Back to Pure Math! Grade-A questions will begin this week with Complex Numbers.

See You and Stay Healthy!

[J2 Chemistry PMCians]

What we did in 2 hours:

This week, we focused on the chemical properties of Period 3 oxides and chlorides, ensuring that you understood the chemistry behind their reactions. This is a notoriously troublesome chapter due to the sheer amount of information you need to recall. Put in the hard work to remember them, and I am sure you will be rewarded well.

What you take home:

The solutions to the Homework to Electrochemistry is found here:

Special Mention:

Next lesson, we will cover the chemistry behind Group 2 and 17 elements.

See you and work hard!
