Hello I really need help how to examine factors what affect the oxidation of pyrite in acid sulphate soils and how to measure it

"Weather Balloon" and "Scuba Diving" relationships Hello so I am suppose to state any relationships between a "Weather Ballon" and "Scuba Diving" those could include equations, laws, both rely on a source etc. I know that for the weather balloon the higher you go up the less pressure there is...

Homework Statement Hello I've been doing this experiment which is about momentum and kinetic energy. I'm using an air track and using two carts one 3/4 of the way down with 50g weights I will add to it each time I test it this will be the variable i will be changing the cart will stay...

Homework Statement Does anyone know any laws equations or any other relative information between a weather balloon and scuba diving. I need to state their relationships and how the laws and equations can be used in our daily lives. Homework Equations Henry's Law, I'm not sure what else...

Hey does anyone have any good suggestions for an experiment for both of these topics momentum and friction? Because I'm currently doing a physics investigated research task that's about if you go a KM over or mile over it is worse. so i need to do some investigating that links the two topics to...

I am still completely lost I seriously don't know how to do it could you please go through the steps

Homework Statement Hello could someone please help me on how to work this question out I have attached a photo so you can see the question. The equation i think you use is the equation of equilibrium. thanks if someone could please help me! you would be my life saver! Homework Equations...

Yes I know that so after I've calculated the acceleration what do I do next?

a = 2(s - ut)/t^2 would I rearrange to this??

Yes but how do you get acceleration?

But I don't know how to get acceleration would u be 0 because it started from rest and is the time 30 if I put in equation?

So I divide those 2 then times it by 135 to get the acceleration?

No I don't understand which time to use

Homework Statement A train moves off from a station and accelerates uniformly for 30.0 s over a distance of 225 m. It continues with the speed acquired for another 135 s, then the driver applies the brakes and the train comes to rest with uniform retardation at the next station in a further...
