Which of the following is an example of a biotic factor depending on an abiotic factor?

rewona [7]

Answer:

The correct answer is B. Algae and fungi are biotic; temperature and rainfall are abiotic.. FURTHER EXPLANATION. An ecosystem consists of all living and non-living factors in an environment that interact and that are interdependent with each other.. All living things or factors in an ecosystem are called biotic factors.Examples include organisms like plants, animals, humans, etc.

Air enters a 16-cm-diameter pipe steadily at 200 kPa and 20°C with a velocity of 5 m/s. Air is heated as it flows, and it leaves

igor_vitrenko [27]

Explanation:

(a) We will determine the mass flow rate as follows.

m = $\rho_{1} V_{1}$

= $\frac{P_{1}}{RT_{1}}A_{1}v_{1}$

= $\frac{P_{1}}{RT_{1}} \times \frac{D^{2}}{4} \pi v_{1}$

Putting the given values into the above formula as follows.

m = $\frac{P_{1}}{RT_{1}} \times \frac{D^{2}}{4} \pi v_{1}$

= $\frac{200}{0.287 \times 293 K} \times \frac{(0.16)^{2}}{4} \pi \times 5$

= 0.239 kg/s

Hence, the mass flow rate of the inlet/outlet is 0.239 kg/s.

(b) Now, we will determine the final volume rate as follows.

$V_{2} = \frac{m}{\rho_{2}}$

= $\frac{RT_{2}m}{P_{2}}$

= $\frac{0.287 \times 313 \times 0.239}{180}$

= 0.119 $m^{3}/s$

And, the final velocity will be determined as follows.

$v_{2} = \frac{V_{2}}{A}$

= $\frac{4V_{2}}{D^{2} \times \pi}$

= $\frac{4 \times 0.119}{(0.16)^{2} \times \pi}$

= 5.92 m/s

Therefore, the volumetric flow rate is 0.119 $m^{3}/s$ and velocity rate is 5.92 m/s.

A 30.0-Î¼F capacitor is connected to a 49.0-Î© resistor and a generator whose rms output is 30.0 V at 60.0 Hz. (a) Find the rms

Natali5045456 [20]

Explanation:

Given that,

Capacitor = 30μC

Resistor = 49.0Ω

Voltage = 30.0 V

Frequency = 60.0 Hz

We need to calculate the impedance

Using formula of impedance

$Z=\sqrt{R^2+X_{c}^2}$ .....(I)

We need to calculate the value of $X_{c}$

Using formula of $X_{c}$

$X_{c}=\dfrac{1}{2\pi f c}$

$X_{c}=\dfrac{1}{2\times\pi\times60.0\times30\times10^{-6}}$

$X_{c}=88.42\ \Omega$

Put the value of $X_{c}$ into the formula of impedance

$Z=\sqrt{(49.0)^2+(88.42)^2}$

$Z=101.08\ \Omega$

(a). We need to calculate the rms current in the circuit

Using formula of rms current

$I_{rms}=\dfrac{V}{Z}$

$I_{rms}=\dfrac{30.0}{101.08}$

$I_{rms}=0.30\ A$

The rms current in the circuit is 0.30 A.

(b). We need to calculate the rms voltage drop across the resistor

Using formula of rms voltage

$V_{rms}=I_{rms}\times R$

Put the value into the formula

$V_{rms}=0.30\times49.0$

$V_{rms}=14.7\ V$

The rms voltage drop across the resistor is 14.7 V

(c). We need to calculate the rms voltage drop across the capacitor

Using formula of rms voltage

$V_{rms}=I_{rms}\times X_{C}$

$V_{rms}=0.30\times88.42$

$V_{rms}=26.53\ V$

The rms voltage drop across the capacitor is 26.53 V.

Hence, This is the required solution.
