Answer:
c. 2 m/s
Explanation:
The speed of a wave is given by:

where
v is the speed of the wave
f is the frequency
is the wavelength
For the wave in this problem, we have
f = 4 Hz is the frequency
is the wavelength
So, the speed of the wave is

Mass = Density * Volume
Density = 19.3 g/cm³
Volume = 24 cm³
Mass = Density * Volume = 19.3 g/cm³ * 24 cm³ = 463.2 g
Mass = 463.2 g
Answer:
Here are some examples of tropism in plants : Sunflowers are one of the best examples of positive phototropism , as they always grow facing the sun.
Explanation:
Although some experts consider that perhaps such a clear growth movement should not be considered tropism.
42.6 is the answer I believe because you would do 2,560 divided by 60 if I'm correct.
