Have no idea if I got it right (I think I did), but I remember writing about how there is a lower cross sectional area, and so there would be more more water entering a smaller area which may lead to more turbulent flow and thus create drag.
I don't think its related to Cross sectional area.
Could you plz link the markscheme?
Is there any thread for C3,4 and M1 IAL Edexcel January 2016 exams?

I'm not sure, if theres none, you could start one.

Thx in that case i would have gained the mark because of my statement at the end. In this particular question, all that matters is that somewhere you reference higher drag/friction/resistive force
Can anyone help me with this?

The time he spends falling 1.25m is the same time he spends going 10m horizontally. So this value of time would be the same in both the vertical and horizontal equations. Can you take it from here?

I knew that fact, however I'm confused in the velocity, they're asking for the Initial velocity right?
Moreover, No angles are given so i'm unsure what to resolve.
EDIT: Are we supposed to find the angle to the horizontal with tan?

There is no angle to calculate. This is the whole idea of horizontal and vertical motion being independent
Exams are just around the corner, how is everyone doing?
Less then 2 weeks remaining!
-Thanks in advance
Can anyone send tell me the unit 1 practicals for edexcel

What do you mean by practicals?

Does anyone know why there's a drop in the reaction force when the student is crouching? I know there must be a resultant force downwards because the student is accelerating downwards but what causes the drop in reaction force??
-Thanks in advance

Hi, i think i got the answer to your question, I'm taking the concept from other questions, so i might not be 100% right, but when i look at it, it seems pretty logical.
Take F=ma (downwards)
This can be written as mg-R=ma (as we are considering downward forces as positve, im doing this because the person is accelerating downwards on the scale)
So, therefore R=mg-ma (where 'g' is acceleration due to gravity and 'a' is the person's downwards acceleration).
Therefore the value of 'R' will be lower than the students actual weight (because now its equal to the "student's weight-the students mass*his/her acceleration".
When the student is standing still:
take F=ma (upwards or downwards doesn't matter, lets just take downwards)
So, "mg-R=ma"
since 'a' is zero because he/she is standing still
then, 'R=mg'. Which will be the students actual weight.
Hope I answered your question. Anyway, Good luck for your exams
sorry experiments

1) Acceleration due to gravity
2) Youngs Modulus
3) Viscosity ball bearing
4) Newton 2nd law
These are the main ones...
newtons 2nd law? 😁 can anyone send me the proper links of the videoz? for unit 2 as well

Just YouTube it,
U can also check specification for practicals
