Absorption:
<span>If the wavelength of the light happens to match the distance between two electron levels in the material, it can be absorbed. Light disappears and its energy becomes part of the heat energy of the material. </span>
<span>Metals have so many free electrons that all wavelengths are absorbed -- they are opaque to xrays, visible light, radio waves, everything. </span>
<span>Pigments have specific electron gaps that absorb only the light of a specific wavelength, which we see as color </span>
<span>Transparent materials do not happen to have any gaps between electron levels that match any of the wavelengths of visible light. </span>
<span>During the December solstice the declination of the Sun is at 23.5° South of the equator. During the December solstice, locations in the Northern Hemisphere experience their shortest day. The December solstice is also the first day of winter in the Northern Hemisphere. Locations in the Southern Hemisphere have their longest day on the June solstice. This date also marks the first day of summer in the Southern Hemisphere.
During the June solstice the declination of the Sun is at 23.5° North of the equator. During the June solstice, locations in the Northern Hemisphere experience their longest day.

Answer:
Explanation:
<u>The question is asked in portuguese</u>
<u>Hence, it will be answered in portuguese</u>
1kg = 1000g
e
1 g = 1000mg
então
1 kg = 1 x (1000 x 1000)
1 kg = 1x 1.000.000
1 kg = 1.000.000mg
assim
1 comprimido -------------> 0,025 mg
x comprimido ------------> 1.000.000 mg ( só cruzar)
0,025(x) = 1(1.000.000)
0,025x = 1.000.000
x = 1.000.000/0,025
x = 40.000.000
<h3>1kg são feitos 40.000.000( Quarenta milhões de comprimidos)</h3>
To solve this problem we will apply the concepts related to the conservation of momentum. This can be defined as the product between the mass and the velocity of each object, and by conservation it will be understood that the amount of the initial momentum is equal to the amount of the final momentum. By the law of conservation of momentum,

Here,
= Mass of Basketball
= Mass of Tennis ball
= Initial velocity of Basketball
= Initial Velocity of Tennis ball
= Final velocity of Basketball
= Final velocity of the tennis ball
Replacing,

Solving for the final velocity of the tennis ball

Therefore the velocity of the tennis ball after collision is 11 m/s
