Naw ur pretty accurate, heck collage is the only football worth watching most the time. Hook'um horns!
I would say C and A.
It’s the only option that’s the correct length apart.
Its like the weather man. They are the people you see on the news that use radars ect. To predict the weather.
Hope that helps?
Answer:
Wave speed = 1.25 m/s
Explanation:
Given that the
wavelength = 0.25 m.
Frequency F = 5.0 Hz
The speed of a wave is the product of wave frequency and the wavelength. That is
V = F λ
Where
V = wave speed (m/s)
λ = wavelength (m).
F = frequency (Hz).
Using the formula above gives:
V = 0.25 × 5
V = 1.25 m/s
Answer : The work function of this metal is, 
Explanation : Given,
Wavelength of light = 
Formula used :
where,
E = work function of metal
h = Planck's constant = 
= threshold frequency
= wavelength of light
c = speed of light = 
Now put all the given values in this formula, we get the value of work function of this metal.
Therefore, the work function of this metal is,
