If a resistor, an inductor and a capacitor are connected in series, the phase angle between the voltages of the inductor and capacitor in a RLC series circuit is 180 degrees.

A resistor , capacitor and inductor are key components of a RLC circuit. Resistor doesn't store energy but capacitor and inductor stores energy and that is the reason resistor is called a passive element and inductor and capacitors are called active element.

Inductor leads the current by a phase angle of 90 degrees and the voltage across the capacitor lags the current by 90 degrees, so the phase difference between the voltages of the inductor and the capacitor is 180 degrees in an RLC circuit.

The distance the car would travel when it hit the barrier before coming to a stop is 14.6 m.

The distance travelled by the car before stopping is calculated by applying third kinematic equation as shown.

v² = u² - 2as

where;

when the car stops,  the final velocity will zero, v =  0

0 = u² - 2as

2as = u²

s = u²/2a

The given parameter;

initial velocity of the car, u = 110 km/h = 30.56 m/s

a = 32 m/s²

s = (30.56²) / (2 x 32)

No, the elastic potential energy stored in the pole of a pole vaulter is not the only type of potential energy involved in pole-vaulting.

In pole-vaulting, there are multiple forms of potential energy involved. While the elastic potential energy stored in the pole plays a crucial role, other forms of potential energy include gravitational potential energy and kinetic energy.

1. Elastic Potential Energy: The pole used in pole-vaulting is typically made of flexible materials, such as fiberglass or carbon fiber, which store elastic potential energy when bent or compressed. This stored energy is then released, propelling the vaulter upwards.

2. Gravitational Potential Energy: As the vaulter reaches the highest point of their vault, they have gained gravitational potential energy due to their increased height above the ground. This potential energy is converted into other forms of energy as the vaulter descends.

3. Kinetic Energy: Throughout the vaulting process, the vaulter's body also possesses kinetic energy, which is the energy of motion. The vaulter's initial speed and subsequent acceleration contribute to their kinetic energy, allowing them to gain momentum and clear the bar.

Therefore, while the elastic potential energy stored in the pole is an important component, there are other forms of potential energy involved in pole-vaulting, namely gravitational potential energy and kinetic energy.

As we don't have the final distance, we can't determine the exact power output of the speaker.

To determine the power output of the speaker, we need to use the inverse square law for sound intensity. The inverse square law states that the intensity of sound decreases as the square of the distance from the source increases.

The formula for the inverse square law is: I₁ / I₂ = (r₂ / r₁)²

where:

I₁ = initial intensity (0.25 W/m²)

I₂ = final intensity (unknown, to be determined)

r₁ = initial distance (10 m)

r₂ = final distance (unknown, to be determined)

Rearranging the formula, we have:

I₂ = (r₂ / r₁)² * I₁

Plugging in the given values:

I₂ = (r₂ / 10)² * 0.25 W/m²

Since we don't have the final distance, we can't determine the exact power output of the speaker. The power output of the speaker is not solely dependent on the distance but also on other factors such as the speaker's efficiency and design

Explanation:

A: Because it would equal 19, and 19 is EQUAL than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.

B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.

Hope this helps <3

The inequality 4x − 1 ≤ 19 has less than or equal sign but the inequality 4x − 1 < 19 has only less than sign. The equation 5x + 2 = 47 is satisfied, for x = 9.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

Part A: Explain why x = 5 makes 4x − 1 ≤ 19 true but not 4x − 1 < 19.

The inequality 4x − 1 ≤ 19 is satisfied by 5 because the inequality has less than or equal sign but the inequality 4x − 1 < 19 has only less than sign so for x = 5, the value is equal to 19 which is not true.

Part B: The value from the set {6, 7, 8, 9, 10} makes the equation 5x + 2 = 47 true.

By simplifying the equation, then we have

The time it takes for light to travel across the Milky Way galaxy is approximately 102,000 years (to the nearest thousand)

The speed of light is 186,000 miles per second. The Milky Way galaxy has an approximate diameter of 6 × 10¹⁷ miles. Therefore, we can estimate the time it takes for light to travel across the Milky Way by dividing the distance by the speed of light. Using this formula, we can say that:

Time taken for light to travel across the Milky Way galaxy= 6 × 10¹⁷ miles/186,000 miles per second= 3.23 × 10¹² seconds.1 year has 365.25 days, and each day has 24 hours, each hour has 60 minutes and each minute has 60 seconds.

So the number of seconds in one year = 365.25 days × 24 hours × 60 minutes × 60 seconds= 31,536,000 seconds.

Therefore, we can determine the time it takes for light to travel across the Milky Way in years by dividing the time taken by the number of seconds in a year, as follows:

3.23 × 10¹² seconds/31,536,000 seconds per year= 1.02 × 10⁵ years.

A) The modulation index is undefined. B) The lower-side band (LSB) frequency is 99,500Hz. C) Percentage modulation = 20%

a) The modulation index (m) may be calculated through the usage of the formulation:

m = (Vmax - Vmin) / (Vmax + Vmin)

where Vmax and Vmin are the most and minimum amplitudes of the modulating signal, respectively.

In this case, the modulating sign is vi(t) = 90cos(2π500t) V. The most amplitude (Vmax) is 90 V, and the minimum amplitude (Vmin) is -90 V (for the reason that the cosine feature varies between -1 and 1).

Therefore, the modulation index is:

m = (Vmax - Vmin) / (Vmax + Vmin) = (90 - (-90)) / (90 + (-90)) = 180 / 0 = undefined

b) The carrier frequency is fc =100,000 Hz.

The higher-aspect band (USB) frequency is given via:

fUSB = fc + fm =100,000 Hz + 500 Hz = 100,500 Hz

The decrease-aspect band (LSB) frequency is given by way of:

fLSB = fc - fm = 100,000 Hz - 500 Hz = 99,500 Hz

c) If vi(t) = 120cos(2π500t) V, we will calculate the share modulation using the components:

Percentage modulation = (Vm - Vc) / Vc * 100%

in which Vm is the peak amplitude of the modulating sign and Vc is the peak amplitude of the service signal.

In this situation, Vm = 120 V and Vc = 100 V.

Percentage modulation = (Vm - Vc) / Vc * 100% = (120 - 100 ) / 100  * 100% = 20%

Increasing the modulation amplitude increases the percentage modulation. This outcome is in a larger version within the amplitude of the AM signal, which could result in extended sidebands and a more said modulation impact. The audio content of the modulating signal turns more distinguished, ensuing in a more potent modulation effect inside the AM signal.

The energy per photon associated with a frequency of 1260 kHz is 2.10×10^-25 J.

To calculate the energy per photon, we can use the equation: E = hf, where E represents the energy, h is the Planck's constant (6.62607015 × 10^-34 J·s), and f is the frequency of the photon. Given that the frequency is 1260 kHz, we need to convert it to hertz (Hz) by multiplying it by 10^3:

Frequency = 1260 kHz × 10^3 = 1.26 × 10^6 Hz

Now, we can substitute the values into the equation:

E = (6.62607015 × 10^-34 J·s) × (1.26 × 10^6 Hz)

E = 8.33929859 × 10^-28 J

The answer is given in scientific notation as 8.34 × 10^-28 J. However, the question specifically asks for the answer in the format of 0.00×10^0. To achieve this, we can multiply the result by 10^3 and adjust the exponent accordingly:

E = (8.33929859 × 10^-28 J) × (10^3)

E = 8.33929859 × 10^-25 J

to find the frequencies of the fundamental and the first two overtones for the guitar string with given parameters.

First, let's determine the linear density (μ) of the string:
μ = (mass of the string) / (length of the string)
μ = (3.00 g) / (90.0 cm)
μ = 0.0333 g/cm (convert to kg/m for SI units)
μ = 0.00333 kg/m

Next, we need to find the wave speed (v) on the string:
v = √(Tension / Linear Density)
v = √533 N / 0.00333 kg/m)
v = √(160060.060060 N/kg)
v = 400 m/s

Now we can calculate the frequencies of the fundamental (f1) and the first two overtones (f2 and f3) using the formula:
f = (n × v) / (2 × L)

For the fundamental (n = 1) and the effective length L=60.0 cm (0.6 m):
f1 = (1 × 400 m/s) / (2 × 0.6 m) = 333.33 Hz

For the first overtone (n = 2):

it takes the man 160 seconds or 2 minutes and 40 seconds to row back upriver to reclaim his hat.

The speed of the river's current is 1 m/s, and the canoe's speed relative to the water is 4 m/s downstream. Thus, the man paddles a canoe in a long, straight section of the river. The speed of the man relative to the bank is 4 - 1 = 3 m/s upstream.

The distance that the hat floats downstream during the eight-minute interval is equal to the product of the speed and time:

distance = speed x time= 1 m/s x (8 x 60 s) = 480 m.

The man must paddle back upstream to recover the hat. Since the distance to the hat is 480 meters, he will have to paddle 480 meters upstream. Let's use the formula for velocity and distance;

time = distance / velocity

In this instance, since he is paddling upstream, his velocity is the difference between the speed of the canoe relative to the water and the velocity of the river's current. Thus, his velocity is 4 - 1 = 3 m/s.

Using the formula, we obtain:

The total angular momentum of the two-disk system after the smaller disk is dropped on the larger disk is \(\omega _2 = (I_1\times \omega _1) / (I_1 + m_2 \times r^2)\).

The total angular momentum of the two-disk system after the smaller disk is dropped on the larger one will depend on the initial angular momenta of the two disks and any changes that occur when they collide.

Assuming the system is isolated, the total angular momentum before and after the collision must be conserved. Before the collision, we can assume that the smaller disk has an initial angular momentum of zero since it is not rotating, and the larger disk has an initial angular momentum given by:

\(L_1 = I_1 \times \omega_1\)

where \(I_1\) is the moment of inertia of the larger disk and ω₁ is its initial angular velocity.

When the smaller disk is dropped onto the larger one, there will be a transfer of angular momentum from the smaller disk to the larger one. The final angular velocity of the combined system will depend on the moment of inertia of the combined system, which can be approximated as:

\(I_2  I_1 + m_2 \times r^2\)

Where m_2 is the mass of the smaller disk and r is the distance from the center of the larger disk to the point where the smaller disk makes contact. We assume that the collision is elastic and that no external forces act on the system, so angular momentum is conserved:

\(L_1 = L_2\)

\(I_1 \times \omega _1 = (I_1 + m_2 \times r^2) \times \omega _2\)
