Explanation:
a block of iron in denser then the block of wood
as the atoms in iron are more closely bounded as compared to that in the wood
if both are drop in water iron block sink to bottom while float on the level
The answer would be B.
Since the light source comes from the bottom, you just need to find the sequence from the bottom going up.
It will start with the light source, then go through the slide, which will then go through the objective lens and lastly, the eyepiece lens. In summary, the sequence is:
B. Light --- slide ---- objective lens --- eyepiece lens
Explanation:
let's assume that:
v1= 600ml=0,6l
T1=27°C= 300K
p1=700mmHG=93326Pa
T2=-20°C=253K
p2=500mmHg=66661
V2=?
p1V1/T1=p2V2/T2 => V2=p1V1T2/p2
V2= 93326*0,6*253/66661
V2=212,52l
