Answer:
none of the answers is correct, the time is the same t₁ = t₂ = 0.600 s
Explanation:
This is a kinematics exercise, analyze the situation a bit. The vertical speed in both cases is the same is zero, the horizontal speed in the second case is double (vₓ₂ = 2 vₓ₁)
let's find the time to hit the ground
y = y₀ + I go t - ½ g t²
0 = y₀ - ½ g t²
t = √ 2y₀ / g
with the data from the first launch
y₀i = ½ g t²
y₀ = ½ 9.8 0.6²
y₀ = 1,764 m
with this is the same height the time to descend in the second case is the same
t₂ = 0.600 s
this is because the horizontal velocity change changes the offset on the x axis, but does not affect the offset on the y axis
Therefore, none of the answers is correct, the time is the same
t₁ = t₂ = 0.600 s
They will interfere to create a crest with an amplitude of 0 as it’s basically addition so 2 + (-2) would equal 0 as they cancel out
The separation between the lines of the grating is 13.33μm.
<h3>What is diffraction grating?</h3>
The diffraction grating is the continuous lines with very minute slits or grating space in mm. It divides light composed of various wavelengths into light components by particular wavelength.
dsinθ = nλ
Substitute n =3, λ =490 x 10⁻⁹ m and angle θ =6.33°, we get
d = [3 x 490 x 10⁻⁹ /sin 6.33°]
d = 13.33 x 10⁻⁶ m
Thus, the separation between the lines of the grating is 13.33μm.

As you approach the surface of the sphere very closely, the electric field should resemble more and more the electric field from an infinite plane of charge.
If you check Gauss's law (recalling that the field in the conductor is zero) you will see that if the surface charge density is σ=Q/4πR2, then indeed the field at the surface is σ/ϵ0 as in the infinite charge of plane case.
Such a field is constant, the field lines are parallel and non-diverging, and the infinities associated with the field due to point charge do not arise.
