An interplanetary space probe is flying by Jupiter on its way to the Oort Cloud. The gravity of the sun is pulling it downward with a force of 631 N. Jupiter is simultaneously pulling the probe sideways with a force of 255 N. What is the net force acting on the space probe?

680.6 N

Explanation:

The net force here is the resultant force. Taking that the two given forces act perpendicular to each other then the resultant is the hypotenuse. Therefore, where d is the magnitude of downward force and s is the magnitude of the sideways force. Substituting 631 N for downward force and 255 N for sideways force then

Therefore, the magnitude of net force is equivalent to 680. 6 N

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

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.
