the calculated frequency is 932 Hz.
Even for sensors positioned at significant track offsets, the computation method integrates three different speed calculation techniques to produce estimates for arbitrary train speeds. The second technique is comparable, but it combines a running rms with a previously created "dominant frequency method." The third technique calculates train speed using regression analysis and an analytical vibration frequency prediction model.
given-
train is travelling at a constant speed. f=(π v/L)
The actual frequency of the note emitted by the train.
By applying Doppler effect,
n'=n( v + vs/ v-vs )
=200( 340+220 / 340-220 )
=200( 560/120)
=932 Hz

Answer:
F = 1.19 x 10⁹ N
Explanation:
The electrostatic force between the charged particles is given by Colomb's Law as follows:
where,
F = Electrostatic force = ?
k = Colomb's constant = 9 x 10⁹ N.m²/C²
q₁ = q₂ = charge on proton = 1.6 x 10⁻¹⁹ C
r = distance between protons = 4.4 x 10⁻¹⁰ m
Therefore,
<u>F = 1.19 x 10⁹ N</u>
Answer:
An atom is the smallest part of an element by itself, while molecules are built of multiple atoms.
Answer:
A. how dose each model effect the temperature of a substance
Explanation:
Explanation:
Let a is the linear acceleration of the descending sphere. It is given by,
.......(1) (change in velocity)
Let 
is the angular acceleration α of the rotating wheel. It is given by :
............(2) (change in angular velocity)
Dividing equation (1) and (2) we get :
Since, 
Hence, this is the required solution.
