<span>John Dalton’s model of the atom was the first model of the atom that was proposed. John Dalton discovered the atom which he said composed matter, which is basically anything and everything. He proposed that all matter is composed of atoms which are small and indivisible particles. His model which may be true, is too general and soon were extended by other scientists.</span>
Answer:
Answer:
A. Increasing the number of lines per length.
The direction of acceleration due to gravity is always towards earth, going downwards.
mark me brainliesttt :))
To solve this problem we will apply the considerations of equilibrium on a body, we will decompose the tensions into their respective components and apply the sum of forces and solving equations for the given system.
According to the graph, the sum of the horizontal components would be



The sum of the vertical components is





Therefore the net force on the new vine is 366.2N
The characteristics of the standing wave we can find the backlash for the frequency of the wave when the string is shortened is:
- The new frequency is f = 657 Hz
<h3>How is a standing wave produced?</h3>
A standing wave is produced when a traveling wave meets an obstacle and bounces, the sum of the two waves results in a wave that does not propagate in space.
In the event that the obstacle is a fixed point, there is a node at this point. The expression for the length of the standing wave.
L =
fundamental frequency
L =
second harmonic
L =
third harmonic
L =
general term.
Where L is the length of the chord, lan the wavelength and n an integer.
Wave speed is related to wavelength and frequency.
v = λ f.
Let's substitute.
v =
They indicate that initially the string has a length of L₀ = 327 mm= 0.327m and the frequency is f₀ = 440 Hz.
v n = 2L₀ f₀
v n = 2 0.327 440
v n = 287.76
They indicate that the tension on the string do not changes and the speed of the wave depends only on the tension and the density of the string, therefore it is constant, we assume that the harmonic does not change either, therefore the new length.
v n = 2 L f
Let's substitute.
287.76 = 2 L f
f =
Let's calculate.
f =
f = 656.99 Hz
In conclusion with the characteristics of the standing wave we can find the backlash for the frequency of the wave when the string is shortened is:
- The new frequency is: f = 657 Hz
