The molecule that trap's the sun's energy is chlorophyll.
Answer:
The fundamental resonance frequency is 172 Hz.
Explanation:
Given;
velocity of sound, v = 344 m/s
total length of tube, Lt = 1 m = 100 cm
height of water, hw = 50 cm
length of air column, L = Lt - hw = 100 cm - 50 cm = 50 cm
For a tube open at the top (closed pipe), the fundamental wavelength is given as;
Node to anti-node (N ---- A) : L = λ / 4
λ = 4L
λ = 4 (50 cm)
λ = 200 cm = 2 m
The fundamental resonance frequency is given by;
Therefore, the fundamental resonance frequency is 172 Hz.
Answer:
There should be only one manipulated variable within a scientific experiment so that the experimenter can be certain it is this variable which causes a pattern in the resultant data, if any exists at all. ... A variable within a scientific experiment is something that is changed
Explanation:
Answer:
Explanation:
As we know that tension force in the string will be equal to the centripetal force on the string
so we will have
now we have
now we have
now when string length is 0.896 m and its speed is 71.5 m/s then we will have
<span>The answer would be Vestibular Senses.
Consciousness of body equilibrium and movement are checked by the vestibular
system. The vestibular senses (the feelings of
body rotation and of attraction and gravity) ascend in the inner ear; the sense
organs are the hair cells that give off signals done in the auditory nerve.</span>
