1. Hello,
I do AQA Physics A (A2 now). I've been revising Chapter 9, and on 9.9 there is a small bit on Nuclear Density.

Now, since we learned this in class, I'm still confused on this one bit.
The textbook says that nuclear density is constant for all nuclei (which I get) but the this number is written as '3.4x10^17 kgm^-3'

However, anywhere ELSE I search up 'nuclear density (i.e. online) I find the number is actually 2.3×10^17 kg/m3.I am baffled. Please help.

Look up a few marks schemes and see if it is a mistake in the textbook.
3. I get some saying 2.3 and some saying 1.8
4. 1.8?😱😩
1.8?😱😩
yes
