480nm appears blue
Microwave have a shorter wavelength and higher Frequency than radio wave
<span>v² = u² + 2as </span>
2as = v² - u²
<span>a = (v² - u²) / 2s </span>
<span>a = (20.0² m²/s² - 6.00² m²/s²) / (2 * 50.0 m) </span>
<span>a = (400 m²/s² - 36 m²/s²) / (100 m) </span>
<span>a = (364 m²/s²) / (100 m) </span>
a = 3.64 m/s²
The answer is : B. allow for bonding metals to be stable. Metals, nonmetals all bond to be stable. Metallic bonding is the force of attraction between valence electrons and the metal ions.The electrons and the positive ions in the metal have a strong attractive force between them.
Answer:
5900J
Explanation:
Work=Forse*Distance
work = J, Jewls
100*59=5900
Hop this helps and can u think about brainlist
i put a picture on how to find these answers, if u got any more questions im here
We have a wave function: D(y,t) and we want to know some things about it. 1. The direction the wave is travelling is negative y direction or -y. 2. Since sound waves are longitudinal waves, this sound wave is oscillating along the y axis. 3. The wavelength we can get from k=2π/λ, k is the wave number, λ is the wavelength. So λ=2π/k=6.28/8.96=0.7 m. 4. Before i get the wave speed i will calculate the period of oscillation. It can be calculated from: ω=2πf where ω is angular frequency and f is wave frequency. So f=ω/2π=3140/6.28=500 Hz and the period is T=1/f=1/500=0.002 s. 5. Wave speed is v=λ*f= 0.7*500=350 m/s.
