Answer:

Output power = 500 KW

Explanation:

Given the following data;

Efficiency = 20%

Input power = 2500 KW

To find the output power;

\( Efficiency = \frac {Out-put \; power}{In-put \; power} * 100 \)

Substituting into the equation, we have;

LET Output power = OP

\( 20 = \frac {OP}{2500} * 100 \)

Cross-multiplying, we have;

\( 20 * 2500 = OP * 100 \)

\( 50000 = OP * 100 \)

\( OP = \frac {50000}{100} \)

Output power = 500 KW

The time constant (in ms) of the RC circuit is 3.75 ms. Hence, the correct option is  (d) 3.75 ms.

The rate of decay of the current in a charging capacitor is proportional to the current in the circuit at that time. Therefore, it takes longer for a larger current to decay than for a smaller current to decay in a charging capacitor.A capacitor is discharged through a 20.0 Ω resistor.

The discharge current decreases to 22.0% of its initial value in 1.50 ms. We can obtain the time constant of the RC circuit using the following formula:$$I=I_{o} e^{-t / \tau}$$Where, I = instantaneous current Io = initial current t = time constant R = resistance of the circuit C = capacitance of the circuit

The time constant of the RC circuit is approximately 0.674 m s.

To determine the time constant (τ) of an RC circuit, we can use the formula:

τ = RC

Given that the discharge current decreases to 22.0% of its initial value in 1.50 m s, we can calculate the time constant as follows:

The percentage of the initial current remaining after time t is given by the equation:

I(t) =\(I_oe^{(-t/\tau)\)

Where:

I(t) = current at time t

I₀ = initial current

e = Euler's number (approximately 2.71828)

t = time

τ = time constant

We are given that the discharge current decreases to 22.0% of its initial value. Therefore, we can set up the following equation:

0.22 =\(e^{(-1.50/\tau)\)

To solve for τ, we can take the natural logarithm (ln) of both sides:

ln(0.22) = \(\frac{-1.50}{\tau}\)

Rearranging the equation to solve for τ:

τ = \(\frac{-1.50 }{ ln(0.22)}\)

Calculating this expression:

τ ≈ 0.674 m s

The mass of oxygen gas (O2) occupying the 25.0 L container at a pressure of 665 torrs and a temperature of 55.0ºC is approximately 28.288 grams.

To determine the mass of oxygen gas (O2) occupying a 25.0 L container, we can use the ideal gas law equation:

PV = nRT

Where:

P is the pressure of the gas (in atm)

V is the volume of the gas (in liters)

n is the number of moles of gas

R is the ideal gas constant (0.0821 L·atm/(mol·K))

T is the temperature of the gas (in Kelvin)

First, we need to convert the given temperature from Celsius to Kelvin:

T(K) = T(°C) + 273.15

T(K) = 55.0°C + 273.15

T(K) = 328.15 K

Next, we need to convert the given pressure from torr to atm:

P(atm) = P(torr) / 760

P(atm) = 665 torr / 760

P(atm) ≈ 0.875 atm

Now, we can rearrange the ideal gas law equation to solve for the number of moles (n):

n = PV / RT

n = (0.875 atm) * (25.0 L) / [(0.0821 L·atm/(mol·K)) * (328.15 K)]

n ≈ 0.884 mol

Finally, to calculate the mass of oxygen gas (O2), we need to use the molar mass of oxygen, which is 32.00 g/mol (16.00 g/mol for each oxygen atom):

Mass = n * molar mass

Mass = 0.884 mol * 32.00 g/mol

Mass ≈ 28.288 g

Explanation:

If you build a common-source amplifier with an NMOS input transistor, and you want a current source as a load, and that current source goes from VDD to a node, the type of current source would be the diode-connected transistor.

An NMOS current source implemented as a diode-connected transistor is a type of bipolar transistor circuit that creates a constant current from an input voltage. The collector and emitter of the bipolar transistor are connected together in the circuit, effectively turning the transistor into a diode. The main advantage of diode-connected transistors is that they can generate currents of a specific magnitude and not be influenced by changes in the supply voltage.

The current generated by the diode-connected transistor is almost completely determined by the physical characteristics of the transistor and the biasing resistors used in the circuit. Another advantage of diode-connected transistors is that they may be cascaded in series to create current sources of various sizes. These devices have been commonly used to generate reference currents, voltage-to-current (V-I) converters, and bias currents in linear integrated circuits. So therefore diode-connected transistor is the type of current source, if you build a common-source amplifier with an NMOS input transistor, and you want a current source as a load, and that current source goes from VDD to a node.

Hello this is allina from brainly. I'll be helping you today. Use the formula, v=gt to find the velocity.

For example, the velocity after one second would be g * t = 10 m/s^2 * 1, which would be 10 m/s.

So, just put the time into the equation:

ii. 20 m/s

iii. 30 m/s

iv. 50 m/s

The formula d = 1/2gt^2 is for finding the distance it has fallen in free fall.

SO plug in the value for t into the equation.

i. 5 m

ii. 20 m

iii. 45 m/s

iv. 125 m/s

Use the previous formula (v = gt) to find the time it has fallen:

v = gt

30 m/s = 10 m/s^2 * t

t = 3 s

So it has fallen for 3 seconds.

Use the 3 seconds to find the distance it has fallen in free fall:

d = 1/2gt^2

d = 1/2 * 10 m/s^2 * 3^2 s

d = 45 m

While the car is going towards the standing person on the sidewalk he is listening the pitch of the horn higher then it is.

When the car passes the person on the sidewalk and goes away, the horn's pitch become lower (for the person standing on the sidewalk).

For the driver, the pitch is always the same.

Explanation:

Is the doppler effect.

When the car is approaching, the sound waves must travel a smaller space than the previous one and they take less time to reach the standing person. So, sound waves reach the standing person with a higher frequency.

It happens the opposite when the car is going away: the sound waves need to travel more space and take more time to reach the person on the sidewalk. So, the frequency of the waves is lower.

The minimum wavelength of x-rays produced by the x-ray tubes currently used by dentists can be calculated using the equation λ_min = hc / eV, where λ_min is the minimum wavelength, h is Planck's constant, c is the speed of light, e is the charge of an electron, and V is the accelerating voltage. Plugging in the values, we get λ_min = (6.626 x 10^-34 J s x 3 x 10^8 m/s) / (1.602 x 10^-19 C x 80 kV) = 0.025 nanometers (or 25 angstroms). Therefore, the x-rays produced by these x-ray tubes have a minimum wavelength of 0.025 nm.

Wavelength is commonly designated by the Greek letter lambda (λ). The term wavelength is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids.

Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. In wireless systems, this length is usually specified in meters (m), centimeters (cm) or millimeters (mm).

Answer:

Explanation:

The strength of the electric field e at the equilibrium condition can be calculated using the equation e = vB, where v is the velocity of the charge carriers and B is the strength of the magnetic field.

When charge carriers move through a magnetic field, they experience a force given by the equation F = qvB, where q is the charge on the carriers, v is their velocity, and B is the strength of the magnetic field.

As a result of this force, the charge carriers move in a circular path. However, as they move, they create an electric field in the direction opposite to their motion, which tries to separate them. This electric field generates an electric force given by the equation F = qE, where E is the strength of the electric field.

The charge carriers continue to separate until the magnetic force exactly balances the electric force. At this equilibrium condition, we have: F = F  qE = qvB  Solving for E, we get: E = vB.
