Aforce is a vector that has both and direction.

A force is a vector that has both magnitude and direction.

Explanation:

A force is defined as the amount of pull or push experienced by a body. The force acting on a body can bring about the change in the state of rest or motion of a body.

The physical quantities are broadly divided into two categories.

The scalar quantities are the quantities that have only magnitude and do not require any direction for their representation whereas the vector quantities on the other hand are the quantities that require the magnitude as well as the direction for their representation.

The speed of a body is considered to be a scalar quantity whereas the velocity of the body considered as the vector because the velocity requires the direction along with the magnitude.

Similarly, the distance of a body is the length of a path covered by the body from the initial point. So, it is scalar but the displacement is the shortest distance between the initial and final point. SO, it is termed as vector as it has direction.

Similarly, the force acting on a body requires the magnitude as well the direction for the complete expression of the force.

Thus, A force is a vector that has both magnitude and direction.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
