oh wow , i get it now. Thanks you so much for helping.

I'm confused here... are u saying i should put e^t inside integral and do L{e*t^2}?

This is the exact question... no option of 2/27 :(

In my answer which is 2/((s-1)*(s+1)^3)) , '*' does mean multiplication, so F(2) should be 2/27 , is that correct? ... test got 1/4 however.

But on the test it says its 2/(s^3 *(s-1)), and wolfram alpha confirms it too... The question asked to find F(2).. according to my solution i will get 2/(3^3) which is 2/27 but the answer is 1/4

I'm having trouble with this question. Can anyone please guide me. My Attempt : = 1/(s-1) * L{t^2*e^-t} = 1/(s-1) * (2/(s+1)^3) = 2/((s-1)(s+1)^3)) but that's not the answer , its 2/((s-1) s^3) somehow. The question is attached below.

My attempt--- (are they right) ? Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) -- exo-on N2(l) → N2(g) -- exo by Cl2(aq) + 2 KBr(aq) → 2 KCl(aq) + Br2(aq) ---exo none NH3(g) + HCl(g) → NH4Cl(s) ---endo by S(s) + 3/2 O2(g) → SO3(g) ---endo by

Homework Statement Label each of the following reactions as exothermic or endothermic ("exo" or "endo"), and according to whether work is done on or by the system, or no work is done at all ("on", "by" or "none")? Note that no "endo-on" cases appear here, as these are always thermodynamically...

Nop, can use anything

So I have to design any physics experiment using Box of Matches. Can anyone help me out ?

Could anyone help me out please :)

This is Grade 12 Physics lab assigned to me : Bonus: Performing the lab+making a conclusion to answer the research question. I thought whole day but can't think of any research question with box of matches. Could anyone please help me out with this?

I tried doing this question, but can't seem to do it, could anyone please help me out ?

We never learned Hyperbolic function, so she wasn't expecting that from us
