A rise in temperature increases the kinetic energy of particles be increasing

Kinetic energy of particles in substance increases, with increase their thermal energy and an increase in their mobility. When the solid metal melted to 1300 °C, the closely packed structure changes to more mobile liquid form and thus kinetic energy increases.

Kinetic energy of  a substances  s an energy form generated by virtue of the motion. Kinetic energy of a particles increases with an increase in temperature.

As temperature increases, particles gains thermal energy by which they can weaken the binding force and move apart. Similarly when a solid changes to liquids, the particles have more space to move and thus gains much kinetic energy.

Therefore, when the solid metal melts to liquid form by heating to higher temperature, particles moves apart more energetically where kinetic energy increase. Thus option a is correct.

The maximum kinetic energy of photoelectrons produced by photons of wavelength 2200 å is 5.0eV. Hence the correct option is (d).

The maximum kinetic energy of photoelectrons produced by photons of wavelength 2200 Å can be calculated using the following equation:

Kmax = hc/λ - W

Here Kmax is max. KE of photoelectrons, h is Planck's cons. (6.62 x 10^-34 Js), c is speed of photon i.e. light (2.998 x 10^8 m/s), λ is wavelength of incident photon (2200 Å), and W is work function of metal (the minimum amount of energy required to remove an electron from the metal).

Converting the wavelength from Å to m:

λ = 2200 x 10^-10 m

Using the above equation, we can calculate the maximum kinetic energy of photoelectrons produced by photons of wavelength 2200 Å:

Kmax = (6.62 x 10^-34)(2.998 x 10^8) / (2200 x 10^-10) - W

The value of W can be calculated from the threshold wavelength of tungsten, which is 2700 Å. The relationship between the threshold wavelength and the work function can be expressed as follows:

W = hc/λthreshold

Putting the value of threshold wavelength:

W = (6.62 x 10^-34)(2.998 x 10^8) / (2700 x 10^-10)

Inserting vale for W in equation for Kmax:

Kmax = (6.62 x 10^-34)(2.998 x 10^8) / (2200 x 10^-10) - (6.62 x 10^-34)(2.998 x 10^8) / (2700 x 10^-10)

Simplifying the expression, we get:

Kmax = 5.0 eV

Therefore, the maximum kinetic energy of photoelectrons produced by photons of wavelength 2200 Å is 5.0 eV (Option d).

Explanation:

The Sirius or Dogstar is the brightest star in Earth's night sky.

The time constant of the circuit can be determined from the formula τ = RC. The values given in the question are R = 4.00 MΩ and C = 3.00 µF. Thus, the time constant is given as:τ = RC = (4.00 × 10^6 Ω) × (3.00 × 10^-6 F) = 12 secondsb. The current in the circuit can be found by using Ohm’s law, which states that I = V/R, where V is the voltage across the circuit.

The voltage across the circuit is 12.0 V, so the current is given as:I = V/R = (12.0 V)/(4.00 MΩ) = 3.00 µAThe charge on the capacitor as a function of time can be found using the formula Q = Qmax (1 - e^(-t/τ)), where Qmax is the maximum charge that can be stored by the capacitor. The maximum charge can be found using the formula Qmax = CV, where V is the voltage across the capacitor.

The voltage across the capacitor is the same as the voltage across the circuit, which is 12.0 V. Thus, the maximum charge that can be stored by the capacitor is:Qmax = CV = (3.00 × 10^-6 F) × (12.0 V) = 36 µCThe charge on the capacitor as a function of time is given as:Q = Qmax (1 - e^(-t/τ)) = (36 µC) (1 - e^(-t/12)).

Answer:

The earth's axis of rotation is tilted 66.5 degrees with respect to its orbital plane around the sun and its axis of rotation is inclined 23.5 degrees from the perpendicular, with respect to this plane. The tilt of the earth affects the angle between the sun beam and the normal over a surface.

Earth orbits at an angle, so half the year, the Northern Hemisphere is tilted toward the Sun — this is summer in the Northern Hemisphere, and winter in the Southern Hemisphere. The other half of the year, the Northern Hemisphere is tilted away from the Sun, creating winter in the north and summer in the south.

When the Earth's axis is tilted toward the sun for the Northern Hemisphere, the people in the Northern Hemisphere experience summer, while at the same time, the Southern Hemisphere is tilted away from the sun and the people there experience winter.

The Northern Hemisphere receives the maximum intensity of the sun's rays, while the angle of sunlight decreases in the Southern Hemisphere.

When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures.

The magnitude of the acceleration of point B is 9 rad/s². Given, the angular acceleration of the disk α = 9 rad/s² and angular velocity of the disk ω = 3 rad/s at the instant shown.

To determine the magnitude of the acceleration of point B and the direction of the acceleration of point B. As the disk has angular acceleration α and angular velocity ω, we can find the acceleration of point B using the formula; a = rα + rω² Where r is the distance between point B and point A.

Here, r = AB

Now, the distance AB can be obtained using Pythagoras' theorem;

AB² = AD² + DB²AB² = (0.4 m)² + (0.3 m)²AB = √(0.16 + 0.09)AB = √0.25AB = 0.5 m

Now, substituting the value of r = 0.5 m in the formula of acceleration;

a = rα + rω²a = (0.5 m)×(9 rad/s²) + (0.5 m)×(3 rad/s)²a = 4.5 rad/s² + 4.5 rad/s²a = 9 rad/s²

Therefore, the magnitude of the acceleration of point B is 9 rad/s².

As the disk rotates counterclockwise, the direction of the acceleration of point B will be tangent to the disk, at the instant shown. The focus of acceleration will be in the counterclockwise order as well.

In terms of increasing rotation rate, the objects can be ranked as follows:

white dwarf > black hole (unclear) > neutron star.

The three objects listed, black holes, neutron stars, and white dwarfs, are all astronomical objects that have different properties and characteristics. When it comes to their rotation rates, each of these objects rotates at different speeds, which can be used to rank them in terms of increasing rotation rate.

A black hole is a region of space where the gravitational pull is so strong that nothing, not even light, can escape. Due to its immense gravitational pull, a black hole can rotate very quickly. However, since it is difficult to observe the rotation rate of a black hole, it is not clear where it should be ranked in terms of increasing rotation rate.

A neutron star is a small and dense object that is formed when a massive star explodes in a supernova. Due to its small size and high density, a neutron star can rotate very quickly, up to hundreds of times per second. This makes neutron stars one of the fastest rotating objects in the universe.

A white dwarf is a small and dense object that is formed when a star like our sun runs out of fuel and collapses. White dwarfs are relatively slow rotating objects, with rotation rates typically on the order of days or weeks.

Therefore, in terms of increasing rotation rate, the objects can be ranked as follows: white dwarf > black hole (unclear) > neutron star.

The charge on the point as it passes is 10τ, the charge on this point is 10τ(1-e-10), and the charge that passes this point is 10τ.

The charge that passes this point between t = 0 and t = τ can be calculated using the following equation:

Q(τ) = I0τ

Therefore, Q(τ) = I0τ = I0 × τ.

The charge that passes this point between t = 0 and t = 10τ can be calculated using the following equation:

The magnitude of the speed at the center of a point simple harmonic motion (SHM) is 15.6691 m/s.

Simple harmonic motion (SHM) refers to a type of periodic motion where the restoring force is directly proportional to the displacement and is always directed towards the equilibrium position. The applicable equation of motion is

x=xmaxcos(ωt+ϕo).

Acceleration of a point in SHM = a = -ω2x

Distance of the point from the origin = x = 0.48 mm

Therefore, a = -ω2x = 4.26 m/s2-ω2x = a = -4.26 m/s2ω2 = 4.26/0.48 = 8.875

Therefore, ω = 2πf = √ω2 = 2π√8.875 = 29.665 rad/s

Period of oscillations = Tp = 2π/ω = 0.2122 sFrequency = f = 1/Tp = 4.7065 Hz

Amplitude of motion = xmax = 0.528 mmInitial phase = ϕo = 6π/π = 6 rad

Position of the point at t = 0s: x(t = 0s) = xmaxcos(ωt+ϕo) = 0.528cos(29.665 × 0 + 6) = -0.2284 mm

The time Δt required for a point in SHM to move from the center of motion to the amplitude of motion is of the period of motion. The distance of the point from the origin at the center of motion is given by: x = 0 mm, and the distance of the point from the origin at the amplitude of motion is given by: x = 0.528 mm.

From the applicable equation of motion: x = xmaxcos(ωt+ϕo), the time required to move from the center of motion to the amplitude of motion is given by:

cos(ωt+ϕo) = x/xmaxcos(ωt+ϕo) = cos^-1(x/xmax)ωt+ϕo = cos^-1(x/xmax)ωt = cos^-1(x/xmax) - ϕoωt = cos^-1(0.528/0.528) - 6ωt = -6

Therefore, the time required to move from the center of motion to the amplitude of motion is Δt = Tp/4 = 0.0531 s.At Δt/6 sec after passing the center point of the SHM: x = xmax/6 = 0.528/6 = 0.088 mm

The magnitude of the speed at the center of motion is given by: v = ωxmax = 29.665 × 0.528 = 15.6691 m/s

Therefore, the magnitude of the speed at the center is 15.6691 m/s.

To determine the second power, we first need to convert the minutes to seconds; we know the one minute have 60 seconds and then 4 min is equal to 240 s. Hence have:

Therefore, the fist result is 5 and the second result is 10.

The mass and magnitude of the second particle are calculated below.

The initial velocity of an object is its velocity prior to the effect of acceleration, which causes the change. The velocity will be the final velocity after accelerating the object for some time. When a particle moves at a constant speed, it can be accelerated. When a point object moves in a horizontal circular path at a constant speed, the direction of its velocity vector changes over time. It means that in a uniform circular motion, the object's velocity vector changes over time.

Distance between the charges, r = 3.2 × \(10^{-3}\)m

initial acceleration of first particle, \(a_{1}\) = 7m / \(s^{2}\)

Initial acceleration of second particle, \(a_{2}\) = 9.0m / \(s^{2}\)

Mass of first particle, \(m_{1}\) = 6.3 × \(10^{-7}\)kg

Mas of second particle, m₂ = ?

a) Since, \(F_{1}=F_{2}\)

∴ \(m_{1}a_{1} = m_{2}a_{2}\)

mass of second particle-\(m_{2}\) =\(\frac{m_{1}\times a_{1}}{a_{2}}\)

= \(\frac{6.3\times10^{-7}\times7.0}{9.0}\)

=4.9 × \(10^{-7}\)Kg

b)As, \(F_{1} = F_{2}\)

       = \(\frac{q_{1}q_{2}}{4\pi E_{0}r^{2}}\) = \(m_{1}a_{1}\)

       = 6.3 × \(10^{-7} \times\) 7.0

       = 44.1 × \(10^{-7}\)

∴ q = 7.1 × \(10^{-11}\)C.

(c) The total internal energy change of the fluid during this process is 515.4 kJ.

(d) The process can be represented as an isochoric heating process on the P-v diagram and as an isobaric expansion process on the T-v diagram.

(a) To find the initial temperature, we can use the saturated steam tables. At a pressure of 200 kPa, the corresponding saturation temperature is 373.95 K.

(b) Since the volume doubles, the process is an isochoric (constant volume) heating process. Using the ideal gas law, we can determine the final temperature. The initial and final volumes are related by the equation V_final = 2V_initial. Since the mass remains constant, the specific volume (v) is inversely proportional to the density (ρ). Therefore, ρ_final = ρ_initial/2. Using the ideal gas law, we can calculate the final temperature to be 546.15 K.

(c) The total internal energy change can be calculated using the equation ΔU = mC_vΔT, where m is the mass of the fluid and C_v is the specific heat at constant volume. Given the mass as 0.5 kg, the specific heat of water at constant volume, and the temperature change, we can find that the total internal energy change is 515.4 kJ.

(d) On the P-v diagram, the process is represented as a vertical line at 200 kPa, indicating constant pressure. On the T-v diagram, the process is shown as an upward-sloping line, indicating an isobaric expansion process. The initial state is represented as a point on the left, and the final state is represented as a point on the right.
