hello :
<span>help :
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x =
(-b±√Δ)/2a</span>
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions</span>
Correct answer: <span>Dot-and-cross-diagram
</span>
Dot-and-cross diagrams are used to represent covalent bonds. The shared electron from one atom is shown as a dot, while the shared electron from the other atom is shown as a cross.
When drawing dot-and-cross diagrams for covalent bonds, you only need to show the electrons in the highest occupied energy level, as only these are involved.
The y-intercept is 0 because you can add it to the equation and it won't change your slope.
Step-by-step explanation:
We have,
The wavelength of yellow light, 
Frequency of yellow light, 
It is assumed to find the speed of light in the yellow light.
The speed of a wave is given in terms of wavelength and frequency as :
So, the speed of light in a shade of yellow light is 
.
