**Answer:**

t = 12s

**Explanation:**

Given:

v-initial = 0 m/s

x = 360 m

a = 5.0 m/s^2

Solve:

x = (v-initial)t + 1/2(a*t^2)

360 = 0t + 1/2 (5.0t^2)

360 = 2.5 t^2

144 = t^2

t = sqrt(144) = 12

Therefore, it takes 12 seconds.

**Answer:**

This is TRUE

**Explanation:**

The tree can fall down even though no one did anything to it...

A hard breeze can blow and it can fall down or something else can cause it to topple...

Not only humans can make trees topple over...

**Explanation:**

London dispersion forces will form between non-polar molecules(polar ) that are symmetrical like O₂, H₂, Cl₂ and noble gases.

- The attraction here is because non-polar molecules becomes polar due to the constant motion of its electrons.
- This lead to an uneven charge distribution at an instant.
- A temporary dipole or instantaneous dipole forms.
- The temporary dipole can induce neighboring molecules to be distorted and forms dipoles as well.
- This forms london dispersion forces.

As you mentioned, we will use <span>Equipartition Theorem.

</span><span>H2 has 5 degrees of freedom; 3 translations and 2 rotation

</span>Therefore:

Internal energy = (5/2) nRT

You just substitute in the equation with the values of R and T and calculate the internal energy as follows:

Internal energy = (5/2) x 2 x <span>8.314 x 308 = 32.0089 x 10^3 J</span>

**Answer:**

**Explanation:**

Intensity of light is inversely proportional to distance from source

I ∝ 1 /r² where I is intensity and r is distance from source . If I₁ and I₂ be intensity at distance r₁ and r₂ .

I₁ /I₂ = r₂² /r₁²

If r₂ = 4r₁ ( given )

I₁ / I₂ = (4r₁ )² / r₁²

= 16 r₁² / r₁²

I₁ / I₂ = 16

I₂ = I₁ / 16

So intensity will become 16 times less bright .

"16 times " is the answer .
