A physics joke today :) This one is kinda easy and you can get it if you passed high school physics. I post it here today just because I saw it today on Pinterest and I love cats.

Joke explained: mew is a Greek Letter μ, the coefficient of friction. f=μN, so friction is relevant to NOT gravity BUT normal force, the force pendicular to the surface the object is on. By the way, there are two kinds of frictions: static fs=μsN and kinetics fk= μκN. μκ and μs depend on the roughness of the two surfaces touching each other. μs can not be bigger than μκ (guess why~ or ask me in DM)

If the force is bigger than friction, the object accelerates. If smaller, it either doesn’t start moving or it decelerates.

So the smaller the mew, the faster the cat slides down the roof :) And mew sounds like meow, of course.

CBSE have announced Term 2 exams starting from April 26th 2022.

1) This gives a very short gap after a student completes JEE(Main) 1st Attempt ---April 16th to 21st, 2022

2) Exam pattern for Term 2: Theory paper 80 marks, 2 hours duration, questions would be Short type and Long type, not just Objective type

3) Total marks for Term 2 evaluation: 100 marks, dividied into , a) Theory paper , example 80 marks , b) Internal assessment or Practicals : example 20 marks (different for subject to subject)
