How can we solve this easily?

I realised many of us would be having our practical tests around this time period, so wanted to collate some tips to use pertinent to practical exams when actually doing the test... feel free to share!!!

When we are answering the "assess" questions especially pertinent to the reliability, accuracy and the validity of an experiment, can we consider an experiment to be unreliable, inaccurate or invalid even if there is a single variable that diminishes these three scientific criteria? I have come...

@ExtremelyBoredUser I guess that is just the 'critical speed'.... Thanks!!

^^^^^^^^^^^^^^^^^^^ @jimmysmith560 Pls help!!!!

What are the main components of a method - this will be helpful for anyone who has an upcoming prac test this term? I do realise that the steps must be numerical, must start with verbs, must be valid, accurate and reliable - are there any others? Thanks!!!

@ExtremelyBoredUser Smartttttttt!

Help with part (b)!! thanks @jimmysmith560 @ExtremelyBoredUser ......

@zbolland Wow congrats on that atar 👏👏👏

I used contradiction and got some sketchy proof which I am not sure is valid - how would you guys go about this?

I wanna make sure that I fully understand what the contraposition statement would be... what did you guys get for this?

Don't you experience a zero gravitational force when you are in the centre of mass of either planet, since the overall vector sum would cancel out when you are in the centre as opposed to being somewhere else like the surface of the earth?

Do you have the full question?

Where would the greatest amount of gravitational force produced between two planets, perse earth and mars as per Newton's universal gravitation? I am thinking at the centre of both planets? what would the answer be with reasoning - thanks in advance!

- As a satellite enters into orbit, its kinetic and potential energy is increased right? if so, how is energy conserved - can someone correct me if I am wrong and me work this out :)!!

For part (a) I wrote that Model X assumes the gravitational field strength to remain the same and that Model Y and X both assume that only a difference in potential energy occurs - is this valid or what would be a better answer?

@jazz519 got it thanks!

For your second question, it honestly just reflects the societal construct at that time wherein men would be the ones who would physically go to war, whereas women were not allowed - hence they metaphorically engage in conflict through cursing...

If we assume that both the weak acid and weak base ionise to the same extent, can we conclude that the pH will have to roughly about 7? (At least in terms of titration curves)...

Critically evaluate how your understanding of social or personal values are influenced by the textual conversation between your pair of prescribed texts. In your responses, use detailed textual references to compare the composers’ representation of these values. How would you guys approach the...
