Answer:
wavelength is 20.71 cm
Explanation:
given data
wave = 43.0 vibrations
time = 29 s
wave travels = 430 cm
time t2 = 14 s
to find out
wavelength
solution
we know here wavelength formula that is
wavelength = velocity / frequency .........................1
here frequency = 43 / 29 = 1.4827 Hz
and velocity = 430 / 14 = 30.71 cm/s
so here from equation 1 put all value
wavelength = velocity / frequency
wavelength = 30.71 / 1.4827
wavelength = 20.71 cm
so wavelength is 20.71 cm
The average velocity can be calculated using the formula:
v = d / t
For the 1st car, the velocity is calculated
as:
v1 = 8.60 m / 1.80 s = 4.78 m / s
While that of the 2nd car is:
v2 = 8.60 m / 1.66 s = 5.18 m / s
Now we can solve for the acceleration using the formula:
v2^2 = v1^2 + 2 a d
Rewriting in terms of a:
a = (v2^2 – v1^2) / 2 d
a = (5.18^2 – 4.78^2) / (2 * 8.6)
a = 0.23 m/s
Therefore the train has a constant acceleration of about
0.23 meters per second.
I can conclude that the aluminum heats up faster then the water, since how they are made up is more different, each has a different compound to it, plus water is more denser<span />
The chromosome pair that attaches to fiber stretching is called Centrioles
Answer:
Pluto
because the the gravitation strength is small, so it will be accelerating slow
