we did an experiment involving GPE and i am trying to understand our equation. We launched a cart up a ramp with a spring and have graphed the height the cart went and then the mass of the cart and got an equation of h=A/m where A=22m

now we did a little inclass and from all the experiment we use GPE =18mz, so i am thinking the A being 22 is close to 18, but there is some conversion present in there and cant figure it out. any help would be appreciated.

thanks

Can you help me write a chemical reaction equation ( EX. Au+ Ag --> blah blah) to these balanced ( I know this is a lot so u don't have to answer all four but if u could that would be great)

*Iron - Fe (III) ( 3+) + thiocyanate ( charge -1) -->*

*calcium- Ca (2+) + oxalate ion- C2O4 (-2)-->*

*Silver- Ag (+1) + Chloride- Cl (-1) ---->*

*Copper (II) Cu ( 2+) + Phosphate- PO4 (-3) ---->*


THANK YOU!
