Now we will consider a two-dimensional arrangement of charges. a point charge q1=2.0μc is located on the positive y-axis at y=0.30m, and an identical charge q2 is at the origin. find the magnitude and direction of the total force that these two charges exert on a third charge q3=4.0μc that is on the positive x-axis at x=0.40m. what is the magnitude of the net force on q3 if q1=2.0μc, as in the example, but q2=−3.0μc? express your answer in newtons to two significant figures. what is the direction of the force on q3 if q1=2.0μc, as in the example, but q2=−3.0μc? express your answer in degrees below the −x axis as an integer.

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders

happy to

pls mark as brainliest.

prolly a beacuse the momentuem the car has increases while going down hill

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.
