Can you please solve February / March 2019 please??

[kushalpadshala]

Thank you today is my exam and you helped a lot
You should make more paper solving vedios for physics

sir at 12:44 question 11 when do we know to use "work done= change in KE" or "work done = change in ke+ "change in gpe"

[sirishmenon]

Why in question 23 did you multiply the speed of light into the time taken

[syedmujahedali]

Why did you subtract in question number 8
Shouldn’t conservation of momentum is m(1)u(1)+m(2)u(2)=m(1)v(1) + m(2)v(2)
Or total momentum before is equal to total momentum after???? Not resultant momentum?

Untelated but I luv ur Irish accent, it gives me clarity in understanding.😭

[ayesiddiq]

THANK U!!! But srsly how can any1 be this smart?!

[mustafamohamed]

for question 18.. please explain why length doesn't affect the sensitivity of a thermometer. I thought that if there is increase in length then the thermometer can more likely be able to reach a higher scale such as for example 200 degrees.

[abdulrahmanshoaib]

Hello sir, for question 20, when you explained why it cannot be D, why can't we use the equation P=IV where if the voltage is halved P would be halved???

[cabbage]

Thank you so much, you're a life saver.

[srushti]

For Q11 - Velocity is not constant in the travel. How only 5m/s is used for KE?

[awsafrkhan]

FOR QUESTION 4, CAN YOU PLS TELL WHY IT CANT BE OPTION C?

[_kemo]

What PDF Viewer do you use? it seems pretty handy for annotation

[raidm]

in q8 momentum before equal momentum after the... what?

[happynightcores]

thank you for this video it helps a lot

[minvs]

Thank you, this was beyond helpful <3

Hello, I have a question about q6. You found the spring constant by rearranging F=kx, but what I tried to do was find the gradient of the straight line (since the gradient of an extension-load graph is the spring constant). The gradient is change in y / change in x, so I got the same fraction but the other way around: 15cm/5N. Obviously this is wrong, but why? Shouldn’t the gradient equal the spring constant? Or have I misunderstood something?
