To calculate the distance, the equation would be:

distance = acceleration X time² / 2

Assuming the stone is held at a complete stop before dropping, the acceleration would be equal to gravity which is 9.8m/s².  So:

d = (9.8m/s²)( 6s)² / 2

The diver was most likely wrong because of refraction. Light bends in water, leading to some optical illusions. In the case of the pool, the light bends as it enters the water, making it look shallower than what it really is when looked at from the top. Light rays reflected from the bottom of the pool are refracted at the surface of the water, however our eyes trace the light rays back into the water as though traveled in a straight line, and not refracted at all. This results in an image of the object that appears at a shallower depth to where it really is.

The Divergence Theorem is true for the vector field F(x,y,z)=3xi+xyj+3xzk on the region E, which is the cube bounded by the planes x=0,x=3,y=0,y=3,z=0,z=3.

Explanation: The Divergence Theorem states that the flux of a vector field across a closed surface is equal to the volume integral of the divergence of the vector field over the enclosed volume. In this case, the cube is a closed surface, and the vector field F has a constant divergence of 6. Therefore, by the Divergence Theorem, the flux of F across the cube is equal to 6 times the volume of the cube. The volume of the cube is (3^3)=27, so the flux of F across the cube is 6 times 27, which is equal to 162.

The correlation function of white noise is zero for all values of τ except when τ is equal to zero.

The correlation function of a white noise frequency after Fourier transformation in quantum physics can be determined by using the Wiener-Khinchin theorem. The Wiener-Khinchin theorem states that the correlation function of a stationary random process can be calculated using the power spectral density of the process. In the time domain, the correlation function R(τ) of a stationary random process is defined as the expected value of the product of two variables at different times. The Fourier transform of the correlation function is known as the power spectral density (PSD) of the process.

The PSD is the square of the magnitude of the Fourier transform of the signal. In quantum mechanics, the Wiener-Khinchin theorem applies to white noise in the frequency domain after Fourier transformation. For white noise, the PSD is constant over all frequencies. The PSD for white noise is given by the constant c. Therefore, the correlation function R(τ) of white noise is given by: R(τ) = c δ(τ)where δ(τ) is the Dirac delta function. This shows that the correlation function of white noise is zero for all values of τ except when τ is equal to zero. When τ is equal to zero, the correlation function is equal to the constant c.

The efficiency of the engine is 83.4% assuming  that the

heat capacity is 21 J/K and the universal gas constant is 0.08206 L · atm/mol/K =8.314 J/mol/K.

Efficiency is described as the often measurable ability to avoid wasting materials, energy, efforts, money, and time while performing a task.

The efficiency of the engine is given by:

E = W/Q

where;

W = the work done in the four steps,

Q = the energy input

Since there at four steps in a cycle:

E = w1+ w2 +w3+ w4/ q1+ q2+q3+q4

We calculate that the work done in the first step (isothermal expansion)

n= 1 mole, T1 = 402 K, V2 = 41.2 L, V1 = 18.5 L

We also solve for Steps 2 and 4 are constant volume processes,

We also calculate  work done in the third step (isothermal expansion) is

where;

n = 1 mol, T3 = 273 K, V4 = 41.2 L, V3 = 18.5 L

The electric field at point P is \({2.12\times10^2\ \mathrm{\frac{N}{C}}\ \hat z}\)

Given values: Radius, r = 1.80 cm Charge density, σ = +4.80 p C/m² z-coordinate, z = 2.64 cm

The electric field at point P at z = 2.64 cm is to be determined.

Let the origin of the coordinate system be the center of the circular hole.

Take the z-axis perpendicular to the surface of the nonconducting material.

The surface charge density is uniform, that is, it has the same magnitude and direction at each point.

Use the expression for electric field due to a charged disk to determine the electric field at point P.

Electric field due to a charged disk at a point on the axis of the disk:  \(E=\frac{1}{4\pi\ϵ_0}\frac{\sigma}{2}(1-\frac{R^2}{R^2+z^2})\) Here, \(\ϵ_0\) is the permittivity of free space.

R is the radius of the disk.

z is the distance from the center of the disk.

The expression for the electric field reduces to \(E=\frac{1}{4\pi\ϵ_0}\frac{\sigma}{2}(1-\frac{r^2}{r^2+z^2})\hat z\)

The electric field at point P is \(\begin{aligned} E&=\frac{1}{4\pi \ϵ _0}\frac{ \sigma }{2}(1-\frac{r^2}{r^2+z^2})\hat z\\ &=\frac{1}{4\pi \times 8.85\times10^{-12}}\frac{4.80\times10^{-12}}{2}(1-\frac{(1.80\times10^{-2})^2}{(1.80\times10^{-2})^2+(2.64\times10^{-2})^2})\hat z\\ &=\boxed{2.12\times10^2\ \mathrm{\frac{N}{C}}\ \hat z} \end{aligned}\)

(a)The force constant (k) is 700N/m.(b) Work done (W) while drawing the bowstring back is 252J.(c) speed of the arrow (v) while releasing from the bowstring is 35.49m/s.

It states that “ The applied force (F) is equal to constant k times the displacement or change in length.”

Mathematically,

F=kx

Where F= applied force in newton(N).

k= constant

x= displacement in m.

In the above question given,

Force F = 420N

Displacement x= 0.60m

And mass m= 0.20kg

a) For calculating k, applying Hooke’s law we get,

F=kx

k= F/x = 420/0.60=700N/m

b) We know work done is equal to the product of force and distance.

Now

W= Fx= 420*0.60=252J

c) Here the bow is pulled backward with a force of 420N so that the kinetic energy stored by the bow

is equal to the Kinetic energy given by the arrow.

Applying law conservation of energy

Initial total energy = final total energy

½ kx2=½ mv2

Now

v2= kx2/m

v=sqrt(kx2/m)

v= sqrt(700*(0.60)2 /0.20)

v=35.496m/s

Hence the force constant k is 700N/m and the work done while drawing the bowstring is 252J and the velocity of the arrow is 35.496m/s.

The refractive index of the material is 0.

When the ray is incident on a transparent surface at an angle of 360 and the angle of refraction within the material is 27°, the refractive index of the material can be determined. The formula for Snell’s law is used to calculate refractive index. It states that: `sin i / sin r = n where i is the angle of incidence, r is the angle of refraction and n is the refractive index`.Snell’s law can be re-arranged to make n the subject of the formula to be: `n = sin i / sin r`Hence, we can calculate the refractive index as follows:

For the incident ray, i = 360° and the angle of refraction within the material, r = 27°.n = sin i / sin r= sin 360°/ sin 27°= 0/1 (since sin 360° = 0)= 0Therefore, the refractive index of the material is 0. T

Based on the relationship between a star's mass and its luminosity, as described in Chapter 5 of your textbook, we can determine the relative luminosity and lifespan of stars with different masses compared to the Sun.

For a star that is 10 times more massive than the Sun:

According to the mass-luminosity relationship, more massive stars have higher luminosities. Since the star is 10 times more massive than the Sun, we can assume it will have a greater luminosity. However, without specific data on the exact relationship between mass and luminosity, we cannot determine the precise relative luminosity value. As for its lifespan, more massive stars tend to have shorter lifespans than lower-mass stars. Therefore, we can expect the star that is 10 times more massive than the Sun to have a shorter lifespan compared to the Sun's 10 billion years.

For a star that is 1/3 as massive as the Sun:

Similarly, using the mass-luminosity relationship, less massive stars have lower luminosities. If the star is 1/3 as massive as the Sun, we can expect it to have a lower luminosity compared to the Sun. Again, without specific data, we cannot determine the exact relative luminosity value. Regarding its lifespan, less massive stars typically have longer lifespans. Therefore, we can expect the star that is 1/3 as massive as the Sun to have a longer lifespan compared to the Sun's 10 billion years.

In summary, a star that is 10 times more massive than the Sun would likely have a greater luminosity and a shorter lifespan, while a star that is 1/3 as massive as the Sun would likely have a lower luminosity and a longer lifespan.

Explanation:

Work = change in KE = \(KE_{f} - KE_{i}\)

KE initial is 0 because the initial velocity is 0. Therefore, work is equal to final kinetic energy. With that:

\(W = KE_{f} = \frac{1}{2}mv_{f}^{2}\)

With some algebraic manipulations,

\(v_{f} = \sqrt{\frac{2W}{m} } = \sqrt{\frac{2*450000 J}{1550 kg} } = 24.1 m/s\)
