<u>Answer :</u>

(A)" Sunlight travels through a longer distance at sunset and interacts with more particles ".

Explanation :

The sunlight is made up of seven colors. The wavelength of red light is maximum as compared to other colors.

And as per <em>Rayleigh law</em> I \propto \dfrac{1}{\lambda^4}

Where,

I is the intensity of scattered light

\lambda is the wavelength

The scattering of red light is least.

At sunset, the sunlight travels through a longer distance.This is because they are near to horizon.

Also, there are many particles, dust and moisture are present in the atmosphere in the evening. So, the sun appears reddish.

Hence, the correct option is (A).

An object has a starting velocity of 20 m/s. If it accelerates at a rate of 2 m/s' for 3 seconds,
Ghella [55]

Answer:

26 m/s

69 m

Explanation:

Given:

v₀ = 20 m/s

a = 2 m/s²

t = 3 s

Find: v and Δx

v = at + v₀

v = (2 m/s²) (3 s) + 20 m/s

v = 26 m/s

Δx = v₀ t + ½ at²

Δx = (20 m/s) (3 s) + ½ (2 m/s²) (3 s)²

Δx = 69 m
