Good luck for exam tommorow guys! Thanks for this vid!

[shafimishtiaq]

I still remember how I watched all the atp videos 1 week before the exam from this channel and ended with an A*
Thank you so much forever grateful!

For the last question (Q11 c); isn't it supposed to be 4.8*10^9 -- 1.2*10^9 instead of 1.8*10^9

[itsgamingirlyyt]

sir are we always supposed to round off the answer to two significant figures

[eihabkhan]

So if we write 3250m instead of 3300m is it wrong or right? at 8:44

[LOLLOL-dmbb]

Hello this might be a dumb thing to ask but in question 1 part (ii) Shouldn't it be
acceleration = 9 - 4.5 / time
Instead of 9 - 5 / time??
Since speed at time 20s is 9.0m/s
Wouldn't the speed at 10s just be half of 9.0m/s which is 4.5m/s
Hence forming the equation 9 - 4.5 / time?
Which would be acceleration = 4.5/10
Therefore acceleration = 0.45ms-2

[samridhdas]

i have my exam in 30 minutes thnx for everything :)

[tayeb]

U did a mistake sir at the last question u wrote 1.8 it should be I wasted my 15 mins bcz of this mistake

[aliahsan]

Could you please improve the audio? the rest vid was pretty good. I appreciated the help. God bless you.

[abdulrahmanur-rehman]

are you guys going to do maths(Edexcel) maths paper 1 was today(5/12/19) and paper 2 is on 6th June

[farahabdelhafez]

Hi, how do you know to what significant figures we have to round our answers to? Will they still give us full marks for a question if we do not round our answer?

[tanyapathak]

In question, 3b, why cant we just used the formula Energy transferred is equal to work done? Then it will be 2.7x10^7 = force x 150m, so the ans is 1.8x10^3 N still

[LOLLOL-dmbb]

Also, can question 3 part (b) be solved by
Kinetic Energy = Force x Distance
2.7 x 10(to the power 7) = F x 150m
2.7 x 10(to the power 7) / 150 = F
1.8 x 10(to the power 5) = F
Please reply my exam is tomorrow and my concepts are all mixed up due to last minute cramming

[iiiValkyrie]

I just finished the exam now i did great all the thanks for u 🙏🏻

[aimanjaved]

Can you solve 2019 papers it would be very helpful if you can

[faisalserang]

Hello. Can you pls explain part ii at 34:20 in more detail? I have no clue what the answer means.

[iffataraa]

Forth one isn't supposed to be 1.2 because 4.8 minus 1.2 gives 3.6 you wrote 1.8. In calculation

[aishath]

It would be more helpful if you explain more

[basilmuhammad]

Can you solve 2019 may june and october november

[justshan]

Thank you so much for this video.
Appreciate it.
