Answer:
id say D
Explanation:
because its the only answer that has to do with colors and visable light
but A and B also have to do with eachother so i feel like it could be with one of those but it def isnt C
I am sorry if i am wrong, let me know tho!
The ball's vertical velocity at the time it just passes over the goal is 0 m/s. Its initial vertical velocity is unknown and we denote it by 
, where 
here is the ball's initial speed. Vertically, the only force acting on the ball is gravity, which attributes a downward acceleration of 9.8 m/s^2. We expect the maximum height achieved by the ball to be 2.4 m, so we can find the initial speed by solving
The correct answer among the choices above is option C. <span>Beryllium, Be, and chlorine, Cl, form a binary ionic compound with a one-to-two ratio of beryllium ions to chloride ions.</span> The chemical formula for the compound of beryllium and chlorine is BeCl2.
hmmmmmmmmmmmmmmmmm ask someone else sorry if im not helping
For any periodic wave
<span>v = f λ </span>
<span>where </span>
<span>v = velocity </span>
<span>f = frequency </span>
<span>λ = wavelength (distance between 2 successive crests) </span>
<span>This means that </span>
<span>λ = v/f </span>
<span>Assuming that v stays the same while f increases, λ must DECREASE.
I hope this helps
