Answer:
It reveals that light is a wave
Explanation:
Diffraction is the property of a wave in which there is a bending of the wave about the corners of an obstacle or aperture into the geometrical shadow of the obstacle or aperture.
This simply implies that a wave bends or spreads out when it passes through openings. Since the light diffracts through small slits and diffraction has been shown to occur in water waves and sound waves, this property of diffraction can only be characteristic of a wave and thus, this evidence reveals that light is a wave.
Because dark line spectra result from passing white light through ionized gasses and plasmas, which is what the atmosphere of stars are made of. These frequencies are scattered by the star's atmosphere as it leaves the surface (photosphere) of the star, and don't make it to earth.
Explanation:
8 m × (1000 mm / m) = 8000 mm
2.4 ounces is the average weight of a hot wheels car.
Let:
<span>m- 0.0600Kg </span>
<span>v1- +50.0 m/s </span>
<span>v2- -42 m/s </span>
<span>a) </span>
<span>momentum1 - momentum2 = impulse </span>
<span>p1 - p2 = Ft </span>
<span>m(v1 + v2) = Ft </span>
<span>Ft = 0.54 N-s </span>
<span>b) </span>
<span>Work is traditionally force times distance but an easy way to get through this one is to think logically and keep your units straight: </span>
<span>The racket creates an overall velocity of 90 m/s for the ball: </span>
<span>W=(Ft)*(V) </span>
<span>W=0.54 N-s * 90 m/s </span>
<span>W=48.6 N-m = 48.6 J</span>
