No difference - same as 5.0000 kg or 0005.0 kg or 0000005 kg and so on.
Sorry No. They do not evolve. Although they have less than .0000005% of a rate of at least being seen let alone caught.
There is a range of wavelengths for visible light. Violet is at the short wavelength end of the range(about 400 nm) and Red is at the long wavelength end of the range(about 600 nm). Yellow is in the middle with a wavelength of about 500 nanometers . That would be .0000005 meters.
You need to use the equation of the electric force is equal to "coulombs constant" mulitplied by charge one multiplied by charge two and all of that divided by the distance of the two charged particles... the equation looks like this...Fe = (K * Q1 * Q2 ) / rIn your problem... (K is always equal to 9*109 N*m2/C2)Q1 = .0000025 CQ2 = -.0000005 Cr = .05 mI converted all the values given into the proper unit. The charges should always be solves while using Coulombs... not micro Coulombs. The distance (r) should always be in meters not centimeters.So just solve it. Your answer should be -2.25 N.
