A student pushes a 0.5 kg lab cart with a force of 3 Newtons. Determine the acceleration of the cart in m/s2.

the acceleration of the cart given its mass and force exerted is 6m/s².

Given the data in the question;

Mass of lab cart;

Force applied;

Acceleration of cart;

To determine the acceleration of the cart, we use the expression from Newton's second law of Motion:

Where F is force exerted, m is mass and a is acceleration

We substitute our given values into the equation

Therefore, the acceleration of the cart given its mass and force exerted is 6m/s².

The acceleration is  6

Explanation:

Use Newton's second law to solve the problem:

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.
