Answer:

a)

b)

Explanation:

From the question we are told that:

Width of diffraction grating

Width of silt

Distance

a)

Generally the grafting element is the distance b/w the silts

Therefore the grafting element is

b)

Generally the equation for diffraction state is mathematically given by

Since

Therefore

Therefore orders observed with is

**Answer:**

Atoms are single neutral particles.

example: Ne, O

Molecules are neutral particles made of two or more atoms bonded together.

example:O2,HCl

**Answer:**

-1000 N

**Explanation:**

First calculate the acceleration:

v² = v₀² + 2a(x - x₀)

(0 m/s)² = (100 m/s)² + 2a (0.05 m)

a = -100,000 m/s²

Now calculate the force:

F = ma

F = (0.010 kg) (-100,000 m/s²)

F = -1000 N
