If a vibrating string is made shorter (i.e., by holding your finger on it), what effect does

1 answer:

4 0

Pitch and frequency are more or less the same thing - high pitch = high frequency.
The freqency of vibration of a string f = 1/length (L) so as length decreases the frequency increases.

Glycolysis. In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule.
Pyruvate oxidation. Each pyruvate from glycolysis goes into the mitochondrial matrix—the innermost compartment of mitochondria.

A uniform rod of length 0.8 m and mass 1.4 kg, has two point masses at each end. The point mass on the left end has a mass 1.2 k

VladimirAG [237]

Answer:

Explanation:

1.2(0) + 3(0.8) + 1.4(0.8/2) / (1.2 + 3 + 1.4) = 0.5285714... ≈ 0.53 m

The displacement (in meters) of a particle moving in a straight line is given by the equation of motion s = 6/t2, where t is mea

ycow [4]

Answer:

Velocity of the particle at time t = a

$v(a)=-\frac{12}{a^3}$

Velocity of the particle at time t = 1

$v(1)=-12m/s$

Velocity of the particle at time t = 2

$v(2)=-1.5m/s$

Velocity of the particle at time t = 3

$v(3)=-0.44m/s$

Explanation:

Displacement,

$s(t)=\frac{6}{t^2}$

Velocity is given by

$v(t)=\frac{ds}{dt}=\frac{d}{dt}\left ( \frac{6}{t^2}\right )=-\frac{12}{t^3}$

Velocity of the particle at time t = a

$v(a)=-\frac{12}{a^3}$

Velocity of the particle at time t = 1

$v(1)=-\frac{12}{1^3}=-12m/s$

Velocity of the particle at time t = 2

$v(2)=-\frac{12}{2^3}=-1.5m/s$

Velocity of the particle at time t = 3

$v(3)=-\frac{12}{3^3}=-0.44m/s$

What is the difference between Laplace Transform and fourier Transform?

Rainbow [258]

The difference between laplace transform and fourier transform is :

Laplace transform is used to get directly the final response of any system. Having transient behavior just by knowing the initial condition of the system

Fourier transform is used to breakup any varying signal into its sin and cosin components

hope this helps
