Answer:
B. 20m/s
Explanation:
The wavelength of a wave can be calculated using the formula;
λ = v/f
Where;
λ = wavelength (m)
v = velocity (m/s)
f = frequency (Hz)
According to the information provided in this question; the wave has a wavelength (λ) of 2m and a frequency (f) of 10Hz.
Using λ = v/f
v = λ × f
v = 2 × 10
v = 20m/s.
Answer: it they are both in the same place
Explanation:I don’t know and don’t care loser
As water freezes its molecules move farther apart. As when water freezes , Its move farther apart .
And the cause of this movement is hydrogen bond that is formed among the surrounding water molecules that causes water molecules to move apart. So as water freezes its molecules move farther apart, it is the correct answer .
The answers that are correct are a, b, and d
Answer:
