Answer: A. carrying capacity

A carrying capacity of the ecosystem or the environment refers to the maximum number of individuals in a population of species that an ecosystem can support in terms of available resources like food, habitat, water and other necessities. If the size of the population exceeds the environmental carrying capacity, this will result in death as all individuals will not be able to derive resources and the population size will return to previous levels.

what is the period of a sound wave whose wavelength is 20.0m? use values from the book and show all of your work
Lera25 [3.4K]
The wavelength of a sound wave is related to its frequency by the relationship:
f= \frac{v}{\lambda}
where
f is the frequency
v is the speed of the wave
\lambda is the wavelength

The wave in our problem has wavelength of \lambda=20.0 m and speed of v=343 m/s (this is the speed of sound in air), therefore its frequency is
f= \frac{343 m/s}{20.0 m}=17.15 Hz

And the period of the wave is equal to the reciprocal of its frequency:
T= \frac{1}{f}= \frac{1}{17.15 Hz}=0.058 s

For a point charge, how does the potential vary with distance from the point charge, r?
mr_godi [17]

For a point charge, how does the potential vary with distance from the point charge, r?

a constant

b. r.

c. 1/r.

d. 1/r^2.

e. r^2.

Answer:

The  correct option is  C

Explanation:

Generally for a point charge the electric potential is mathematically represented as

    V  =  \frac{k  Q  }{r }

Here we can deduce that the electric potential varies inversely with the distance i.e

      V  \  \alpha \  \frac{1}{r}

So

The hydronium ion concentration of your gastric fluid is 1.0 x 10^-2. you drink a tablespoon of milk of magnesia, which raises t
slamgirl [31]

Answer:

[OH⁻] = 1 × 10⁻¹¹ mol/dm³

Explanation:

Since the hydronium ion concentration of the gastric fluid is [H₃O]⁺ = 1.0 × 10⁻².

The pH at this point is pH = -log₁₀[H₃O]⁺ = -log₁₀[1.0 × 10⁻²] = 2

When milk of magnesia is added, the pH increases by one unit, so the new pH is 1 + 2 = 3

Since pH + pOH = 14, then pOH = 14 - pH = 14 - 3 = 11

The hydroxide ion concentration of the fluid is gotten from

pOH = -log₁₀[OH⁻]

11 = -log₁₀[OH⁻]

-11 = log₁₀[OH⁻]

taking antilog

[OH⁻] = 1 × 10⁻¹¹ mol/dm³
