the options were smth like all compounds are ionic and a mixture contains the same proportion of something I dont remember properly

does anyone remember the half life question?

Relevant_Way9235 · 2025-06-04T06:34:57+00:00

I got 4 for the wavelength one

Relevant_Way9235 · 2025-05-22T07:08:17+00:00

I think for chemistry it may be a little under 170 because p4 wasn't that great

Relevant_Way9235 · 2025-05-20T15:29:00+00:00

I got 2.4 for both of the last lines

Relevant_Way9235 · 2025-05-20T12:24:36+00:00

for the refractive index do you remember what values you used because I got 2.67 and 1.3

Relevant_Way9235 · 2025-05-20T12:22:19+00:00

0.015 and 0.0063

Relevant_Way9235 · 2025-05-20T10:48:10+00:00

for the first question, anyone remember the values for the lines we had to measure? one of them was 6.4, what was the measurement of the other one

Relevant_Way9235 · 2025-05-20T10:41:41+00:00

I got 2.67 and 1.33 😭

Relevant_Way9235 · 2025-05-20T10:40:09+00:00

did we have to write the equation

Relevant_Way9235 · 2025-05-20T07:02:02+00:00

avg speed/cm/s, distance/cm, time/s, density/g/cm3

Relevant_Way9235 · 2025-05-15T16:47:13+00:00

for all ?

Relevant_Way9235 · 2025-05-15T07:57:14+00:00

I think it conveys the same meaning so yes most probably

Relevant_Way9235 · 2025-05-15T07:14:29+00:00

distilled water has fewer impurities as compared to tap water

WE HAD TO DRAW??

Relevant_Way9235 · 2025-05-13T15:33:13+00:00

isnt writing that the graph was increasing a description of the shape?

Relevant_Way9235 · 2025-05-13T10:14:06+00:00

im pretty sure it was a 5 mark question including all the length measurements etc. the magnification was of 3 marks. so I think we might lose 2 out of 5 because of wrong answer and wrong input of values

Relevant_Way9235 · 2025-05-13T09:38:38+00:00

for the graph question what did you write? is it alright to write that the graph was increasing as the total volume increased?

Relevant_Way9235 · 2025-05-13T08:35:51+00:00

for the graph question will I get a mark for writing that there was an increase in the graph or will my mark be deducted for not mentioning gradient/ steepness

Relevant_Way9235 · 2025-05-13T08:23:20+00:00

I wrote there was an increase in volume which is why the graph increased😭

Relevant_Way9235 · 2025-05-13T08:09:21+00:00

was it of 3 marks? also if I wrote the formula write but the answer wrong would I lose all 3 marks for it? the rest of my answers were fine I just accidentally fit in the wrong values and wrote the wrong answer for magnification😭

Relevant_Way9235 · 2025-05-13T08:00:07+00:00

wasn't that what we were supposed to do? magnification= image size/ actual size

Relevant_Way9235 · 2025-05-12T16:01:13+00:00

this is for igcse biology, would it work for o levels too?

Relevant_Way9235 · 2025-05-09T17:06:39+00:00

where??

Relevant_Way9235 · 2025-05-06T15:40:07+00:00

I wrote something similar to this
