the surface temperature of the sun is approximately 6000 k. what is the approximate temperature of the sun's corona?

Answer:According to Coulomb's law, the electrostatic force between two bodies is proportional to the product of their two charges. If the charge on A is increased this product increases in size (it must have been non-zero to begin with, since there was a force between them at first). Thus, the force between them rises.

Explanation:

When a series LRC circuit is driven at its resonance frequency, the phase difference between the drive voltage and the voltage across the resistor will be 0 degrees.

Solution - Resonant frequency is the natural frequency where a medium vibrates at the highest amplitude. Resonant frequency is usually denoted as f0. Resonance is witnessed in objects in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions. This is because, at resonance, the inductive and capacitive reactances cancel each other out, resulting in a purely resistive circuit where the voltages across the resistor and the source are in phase.

Electromagnetic waves are a form of radiation that occurs when electric fields and magnetic fields are coupled with each other. Thus, option C is correct.

An electromagnetic field is formed with an electric field and a magnetic field that are dependent on each other. The two fields are perpendicular to each other and travel in that direction as well.

Electromagnetic waves are not elastic waves either and can travel in a vacuum. They are different from mechanical waves as electromagnetic waves can travel in the absence of a medium. They travel at the speed of 3x\(10^{8}\)m/s. Thus, only option C is right.

The magnitude of the change in momentum is therefore 6.12 kg*m/s, and the direction is downward and the floor exerts an average net force of 51 N upward on the ball during the collision.

(a) To find the magnitude and direction of the ball's change in momentum, we need to first find the initial and final momenta of the ball. The initial momentum is given by:

\(p_i = m*v_i\)

where m is the mass of the ball, and \(v_i\) is the initial velocity of the ball before it hits the floor. Substituting the given values, we get:

\(p_i\) = (0.60 kg)(6.0 m/s) = 3.6 kg*m/s

The final momentum is given by:

\(p_f = m*v_f\)

where \(v_f\) is the velocity of the ball after it rebounds from the floor. Substituting the given values, we get:

\(p_f\)= (0.60 kg)(-4.2 m/s) = -2.52 kg*m/s

Note that the negative sign indicates that the direction of the final momentum is opposite to that of the initial momentum.

The change in momentum is given by:

Δp = \(p_f - p_i\)

Substituting the calculated values, we get:

Δp = -2.52 kgm/s - 3.6 kgm/s = -6.12 kg*m/s

The magnitude of the change in momentum is therefore 6.12 kg*m/s, and the direction is downward.

(b) To find the average net force that the floor exerts on the ball, we can use the impulse-momentum theorem:

Δp = \(F_avg\) * Δt

where Δt is the time duration of the collision. Substituting the calculated value of Δp and the given value of Δt, we get:

-6.12 kg*m/s = \(F_avg\) * 0.12 s

Solving for \(F_avg\), we get:

\(F_avg\) = -6.12 kg*m/s / 0.12 s = -51 N

Note that the negative sign indicates that the direction of the average net force is opposite to that of the change in momentum, i.e., upward. Therefore, the floor exerts an average net force of 51 N upward on the ball during the collision.

Answer:

Distance travel (s) = 67 m (Approx)

Explanation:

Given:

Initial speed (u) = 20 m/s

Final speed (v) = 0 m/s

Acceleration (a) = (-3 m/s²)

Find:

Distance travel (s)

Computation:

v² = u² + 2(a)(s)

0² = 20² + 2(-3)(s)

0 = 400 - 6 s

6 s = 400

S = 66.6667 meter

Distance travel (s) = 67 m (Approx)

To obtain a buffer with a pH of 9.55, approximately 80 grams of ammonium chloride should be added to 2.50 L of a 0.150 M NH_3 solution.

The pH of a buffer solution is given by the Henderson-Hasselbalch equation: pH = pKa + log([A^-]/[HA])

where pKa is the dissociation constant of the weak acid (NH_4^+), [A^-] is the concentration of the conjugate base (NH_3), and [HA] is the concentration of the weak acid (NH_4^+). We can assume that the volume of the solution remains constant upon adding ammonium chloride.

From the problem statement, we know the initial volume and concentration of the NH_3 solution. We also know that we want a buffer with a pH of 9.55. Using the value of pKa for ammonium chloride (9.24), we can solve for the ratio [A^-]/[HA] that will give us the desired pH.

pH = pKa + log([A^-]/[HA])

9.55 = 9.24 + log([A^-]/[HA])

0.31 = log([A^-]/[HA])

10^0.31 = [A^-]/[HA]

[A^-]/[HA] = 1.995

We also know that the total molar concentration of the buffer will be equal to the molar concentration of NH_3 in the initial solution (0.150 M) plus the molar concentration of NH_4^+ from the ammonium chloride we add (which we will assume completely dissociates):

[A^-] + [HA] = 0.150 M

Substituting the ratio we just found gives us:

1.995[HA] + [HA] = 0.150

[HA] = 0.0454 M

[A^-] = 0.9046 M

Now we can use the definition of molarity to find the mass of ammonium chloride we need to add to obtain these concentrations in our 2.50 L solution.

Molarity = moles solute / liters solution

moles NH_3 in initial solution = 0.150 * 2.50

= 0.375

To achieve the desired concentrations of NH_3 and NH_4^+ in the final solution, we need to add moles of ammonium chloride equal to [HA] x (volume of solution) = 0.0454 * 2.50 = 0.1135

This additional moles of ammonium chloride will provide the desired amount of NH_4^+ while the original NH_3 concentration remains the same. We can find the mass of ammonium chloride using its molar mass:

mass NH4Cl = moles NH4Cl x molar mass NH4Cl

moles NH4Cl = 0.1135

molar mass NH4Cl = 53.5 g/mol

mass NH4Cl = 0.1135 * 53.5

= 6.06 g

Therefore, approximately 80 grams of ammonium chloride should be added to 2.50 L of a 0.150 M NH_3 solution to obtain a buffer with a pH of 9.55.

To summarize, we can create a buffer solution with pH of 9.55 by adding approximately 80 grams of ammonium chloride to 2.50 L of a 0.150 M NH_3 solution. This calculation was based on using the Henderson-Hasselbalch equation, which relates the concentrations of a weak acid and its conjugate base to the pH of the buffer.

To determine the amplitude of oscillation, measure the maximum displacement of the mass from its equilibrium position. This value represents the distance between the maximum and minimum positions of the mass during one complete cycle of oscillation, and it is expressed in centimeters (cm).

To calculate the frequency of oscillation, measure the time it takes for the mass to complete one cycle of oscillation (also known as the period), and then use the following formula: frequency (Hz) = 1 / period (s). The period can be calculated by measuring the time it takes for the mass to complete a certain number of oscillations and dividing that time by the number of oscillations.

To determine the spring constant of the spring, use the formula: spring constant (N/m) = mass (kg) x (2π x frequency)^2 x amplitude (m) / 4π^2. The mass of the object in this case is 0.293 kg.

In a circuit with a purely resistive load, the phase constant is zero.

The phase constant represents the phase relationship between the voltage and current in an AC circuit. In a purely resistive load, the current and voltage waveforms are in phase with each other. This means that they reach their maximum and minimum values at the same time, and their waveforms are aligned.

Since there is no reactive component (inductance or capacitance) in a purely resistive load, there is no phase difference between the voltage and current. Therefore, the phase constant is zero, indicating that the voltage and current are in phase with each other.

When the radioactive decays in Earth's interior cease, several things will eventually happen to the planet. Finally, the Earth's surface will continue to erode and weather, which will eventually cause it to become flat and featureless. This process will take billions of years, and by the time the radioactive decays in the Earth's interior cease, life on Earth will likely have evolved into something completely different from what we know today.

Firstly, the Earth will cool down, and as a result, the magma in the mantle will also cool and stop flowing. The Earth's inner core will also solidify over time, as it is no longer receiving heat from the mantle.

Secondly, the Earth's magnetic field will weaken, which will have a significant impact on life on Earth. The magnetic field helps protect us from cosmic radiation, so a weaker field could lead to increased radiation exposure and potentially harm life on Earth.

Thirdly, the lack of internal heat will cause plate tectonics to slow down, and eventually, come to a halt. This could have a significant impact on the Earth's surface features, as plate tectonics are responsible for shaping the landscape and creating mountains and oceans.

Decreasing.

Determination of a wave's amplitude:

The amplitude of a sound wave determines how loud or loud it is. A louder sound has a bigger amplitude, and a softer sound has a smaller amplitude.

Higher pitch and sharper edges result from decreasing wavelength and increasing frequency. As a result, increasing the frequency makes sounds sharper while increasing the amplitude or intensity increases the volume.

A sound wave's amplitude measures the height of the wave. When a sound is made, the maximum displacement of the medium's vibrating particles from their mean position determines the amplitude of the sound wave.

The wavelength corresponding to photons with a frequency of 1.039x1015 s-1 is approximately 289.44 nm.

To find the wavelength corresponding to a given frequency, we can use the formula: wavelength = speed of light/frequency. The speed of light is approximately 3x10^8 m/s. We need to convert the frequency from s-1 to Hz, so 1.039x10^15 s-1 is equivalent to 1.039x10^15 Hz.

Plugging these values into the formula, we have wavelength = (3x10^8 m/s) / (1.039x10^15 Hz). Simplifying the expression, we find the wavelength to be approximately 2.89x10^-7 m. To convert this value to nanometers (nm), we multiply by 10^9, resulting in approximately 289.44 nm.
