amazing video!
can you solve nov 2010 v2 Q4 AS 9702 please ?
Mam you are you are do doing great work
For a2 we have a new chapter added
Astronomy and cosmology
Pls make a lecture on it as my exams are near.....
Based on our schedule, we'll probably only reach that chapter some months later tho! :')
@@ETphysics okay ma'am because this chapter is included in 2022 syllabus
I searched in your playlist for this chapter...... but it's okay ma'am
Thank you so much😊
For your great pedagogy i can easily understand the concepts of physics...
so I had a question why is the formula for Hooke's law in math different from physics why do we have two constants one being lambda elasticity modulus and another being the spring constant k. moreover, if k represents stiffness what does lambda represent?
Hmm we're not familiar with the math version, but what is the full math equation with the λ in it?
@@ETphysics [(lambda)(extension)] / natural length. Basically k is replaced by lambda/ natural length
@@maheeneatazaz4872 yes in that case lamda is a constant
13:10 the yellow colour is showing 1|2 fx
plz answer
lol late but its talking about the area under the graph for that triangle. yk likw 1/2 base x height intead of base and height its force and length
State the significance of of point B,C,D,E
