The first blank is character
The last one is eye colour.
The atoms of some materials have no free electrons in their outer orbits. These electrons are busy doing other jobs, like being shared in the orbits of two adjacent atoms. They are so closely held that it is very difficult to pull them away. Most compounds of carbon and hydrogen are like this.
<span>Plastics, whose molecules are made from long combinations of carbon and hydrogen atoms, have few or no free electrons. This means that plastics are poor conductors of electricity (and they are also poor conductors of heat). hope that helped.</span>
Answer:
d₂=232.8 m
Explanation:
We know that formula for resolution given as
θres = 1.22 λ/d
Where
λ=wavelength
d=diameter
Given that resolution should be same.So we can say that
1.22 λ₁/d₁= 1.22 λ₂/d₂
λ₁/d₁= λ₂/d₂
Given that
λ₂=582 nm
λ₁=2 cm
d₁=8000 km
d₂=232.8 m
Apply E=(mv^2)/2 . It will give the answer.
