As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
Answer:
The number of coils of the wire and the strength of the power source.
Explanation:
It is a direct relationship meaning when one increases so does the other. A stronger power source will induce a stronger magnetic force. The more coils the stronger the magnet.

becuase if you take away the 0 then it would change the value of the number
Answer:
0.63 s
Explanation:
We have,
- Height, h = 2.0 m
- Initial velocity, u = 0 m/s
- Acceleration due to gravity, g = 10 m/s²
We have to find the time taken.
⠀⠀⠀⠀⇒ h = ut + ½gt²
⠀⠀⠀⠀⇒ h = ½gt²
⠀⠀⠀⠀⇒ 2 = ½ × 10 × t²
⠀⠀⠀⠀⇒ 2 = 5 × t²
⠀⠀⠀⠀⇒ 2/5 = t²
⠀⠀⠀⠀⇒ √(2/5) = t
⠀⠀⠀⠀⇒ <u>0.63 s = t</u>
Therefore, time taken is 0.63 seconds.
The projectile has a height <em>h</em> at time <em>t</em> given by
<em>h</em> = (14.0 m/s) <em>t</em> - 1/2 <em>g t</em> ²
where <em>g</em> = 9.80 m/s² is the magnitude of the acceleration due to gravity. Solve for <em>t</em> when <em>h</em> = 0 :
0 = (14.0 m/s) <em>t</em> - 1/2 <em>g t</em> ²
0 = 1/2 <em>t</em> (28.0 m/s - <em>g t</em> )
1/2 <em>t</em> = 0 <u>or</u> 28.0 m/s - <em>g</em> <em>t</em> = 0
The first equation says <em>t</em> = 0, which refers to the moment the gun is first fired, so we ignore that solution. We're left with
28.0 m/s - <em>g t</em> = 0
<em>t</em> = (28.0 m/s) / <em>g</em>
<em>t</em> = (28.0 m/s) / (9.80 m/s²)
<em>t</em> ≈ 2.86 s
