Answer:
I say 150 because i aded 850+150= 1000 so yea thats how i got my answer
Explanation:
I'm going to say carrying capacity since carrying capacity is the maximum amount of organisms that can live in an ecosystem. So the reason for there being a maximum of organisms is because, like the question says, organisms usually produce more offspring than the ecosystem can support.
C. added an electron to the outer electron shell.
Explanation:
Atoms consist of three particles:
- Protons: they are located in the nucleus, they have positive charge of
, and mass of ![1.67\cdot 10^{-27}kg](https://tex.z-dn.net/?f=1.67%5Ccdot%2010%5E%7B-27%7Dkg)
- Neutrons: they are also located in the nucleus, they have no electric charge, and mass similar to that of the proton
- Electrons: they orbit around the nucleus, they have negative charge of
, and mass around 1800 smaller than the proton
Normally, atoms are neutral (no electric charge), because they have an equal number of protons and electrons.
However, sometimes atoms can give off or take electrons from other atoms. We have two cases:
- If an atom gives off an electron, it remains with an excess of positive charge, so it becomes a positive ion
- If an atom takes an electron from another atom, it remains with an excess of negative charge, so it becomes a negative ion
Therefore, in order to form a negative ion, the atom must have

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
