Answer:0.38
Explanation:
the formula is f = c / λ
so f= 2.5/6.5
and that equals 0.38 46 and so on so i just rounded it
The wave diagramed in blue.
Ware them down, its like rubbing two pieces of chalk together.
Answer:
Explanation:
1. 
= 
* cos
⇒ 16*cos32 ≈ 13.6 m/s (13.56)
2. 
= * sin ⇒ 16* sin32 ≈ 9.4 m/s
3. 
= 
= 
(the g (gravity) depends on the country but i'll take the average g which is 9.2m/s^2)
≈ 3.6677+1.5 ≈ 5.2m
4. 
= 
=
≈ 23.5m (23.47)
5. -
answer 4 could be wrong, not certain about that one and i don't know 5
Answer:
radius r is 0.414 R
Explanation:
Given data
FCC octahedral site
atomic radius R
to find out
radius r
solution
we know that at FCC octahedral
length of side = 2 R + 2r
and by pythagorean theorem
a = 2√2R
here a = 2R + 2r
so 2R + 2r = 2√2R
so r = ( √2R )- R
r = 0.414 R
so radius r is 0.414 R
