Answer:
the center of the flower or the ovary
Answer:
a. 340.13 m/s b. 680.26 m/s c. our wavelength doubles
Explanation:
a. speed of wave, v = fλ were f = frequency = 301 Hz and λ = wavelength = 1.13 m.
v = fλ = 301 Hz × 1.13 m = 340.13 m/s
b. If we double the frequency then f = 2 × 301 Hz = 602 Hz
v = fλ = 602 Hz × 1.13 m = 680.26 m/s
c. If the speed of the wave is still 340.13 m/s, if we cut the frequency in half, then frequency now equals f = 301 Hz/2 = 150.5 Hz.
Since v = fλ,
λ = v/f = 340.13 m/s ÷ 150.5 Hz = 2.26 m.
Since our initial wavelength λ₀ = 1.13 m,
λ/λ₀ = 2.26 m/1.13 m = 2.
So, λ = 2λ₀ our wavelength doubles
Answer:
2 m/s
Explanation:
Velocity is a vector quantity that is given by:
![v=\frac{d}{y}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bd%7D%7By%7D)
where
d is the displacement of the object (a vector indicating its change in position)
t is the time elapsed
Note that since velocity is a vector, it has both a magnitude and a direction (the same as the displacement).
For the toy train in this problem, we have:
d = 40 m (displacement)
t = 20 s (time elapsed)
So, its velocity is:
![v=\frac{40}{20}=2 m/s](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B40%7D%7B20%7D%3D2%20m%2Fs)
The shortest visible wavelength is the last color you can see
at the blue end of the spectrum.
The light-gathering capacity of a telescope depends on the area
of the main lens in the front, or the main mirror in the back.
That's also the area of the opening of the tube, called the 'aperture'.
To find information, the would take DNA tests.
