When a light ray passes from water (with a refractive index of 1.333) into diamond (with a refractive index of 2.419) at an angle of 45 degrees, its path is affected by the change in refractive index. Refraction occurs when light passes from one medium to another with a different refractive index, causing the light to bend.

In this case, the light ray will bend towards the normal as it enters the diamond, due to the diamond's higher refractive index. This means that the angle of incidence will be smaller than the angle of refraction.

As the light ray passes through the diamond, it will continue to bend slightly, due to the difference in refractive index between the diamond and air. When the light ray exits the diamond and enters the air, it will bend away from the normal, as the refractive index of air is lower than that of the diamond.

Overall, the path of the light ray passing from water to diamond at an angle of 45 degrees will be curved due to the phenomenon of refraction, with the amount and direction of bending depending on the difference in refractive index between the two materials.

Answer:

In Explanation

Explanation:

The transition from ocean to cloud refers to the process by which water vapour in the ocean rises and condenses into clouds. This process is known as evaporation and is a key component of the water cycle.

Evaporation occurs when the sun's energy heats the surface of the ocean, causing water molecules to gain enough energy to escape into the atmosphere as water vapour. As the water vapour rises, it cools and condenses into tiny droplets, which form clouds. The clouds can be made of water droplets or ice crystals, and they can be observed in the sky in different forms, such as stratus clouds, cumulus clouds, and cirrus clouds.

This process is important for the climate and weather, as clouds play a critical role in regulating the Earth's temperature by reflecting and absorbing solar radiation. Clouds also affect precipitation, as the droplets or crystals in the clouds grow and fall as rain or snow. The transition from ocean to the cloud is also important for the water cycle as precipitation, either in form of rain or snow, replenishes the water in the oceans and rivers.

In summary, the transition from ocean to the cloud is the process by which water vapour in the ocean rises and condenses into clouds, known as evaporation, and is a key component of the water cycle. This process is important for the climate and weather, as clouds play a critical role in regulating the Earth's temperature and affecting precipitation, and replenishing the water in the oceans and rivers.

The radius of Jupiter is 11.37 × 10^6 km (approx).

The correct answer to the given question is option D.

Jupiter is a giant planet in our solar system and takes 9.9259 hours to rotate on its axis. The tangential speed of Jupiter is given to be 12,293 m/s. We are required to find out the radius of Jupiter.

Given Data:

Rotation period of Jupiter, T = 9.9259 hours

Tangential speed of Jupiter, v = 12,293 m/s

Formula Used:

Radius of Jupiter, r = v × T / (2π)

Calculation:

We can find the radius of Jupiter using the above formula.

Substituting the given values in the formula, we get:

r = 12,293 × 9.9259 × 60 × 60 / (2π)r = 71,492,602.68 / (2π)r = 11,371,641.26 km ≈ 11.37 × 10^6 km.

Therefore, the radius of Jupiter is 11.37 × 10^6 km (approx).

Answer:

Calor absorbido, Q = 52325 Joules

Explanation:

Dados los siguientes datos;

Masa = 250g to kg = 250/1000 = 0.25kg

Temperatura inicial, T1 = 10°C to Kelvin = 273 + 10 = 283K

Temperatura final, T2 = 60°C to Kelvin = 273 + 60 = 333K

Capacidad calorífica específica = 4186 j/kg.K.

Para encontrar la cantidad de calor necesaria;

La capacidad calorífica viene dada por la fórmula;

\( Q = mct \)

Dónde;

Q representa la capacidad calorífica o la cantidad de calor.

m representa la masa de un objeto.

c representa la capacidad calorífica específica del agua.

dt representa el cambio de temperatura.

dt = T2 - T1

dt = 333 - 283

dt = 50 K

Sustituyendo en la fórmula, tenemos;

\( Q = 0.25*4186*50\)

\( Q = 52325 \)

Calor absorbido, Q = 52325 Joules

" 50 W " means " 50 Watts "  or  " 50 Joules per second ".

Explanation:

It looks like you're given

\(x(t) = -11\,\mathrm m + \left(1\dfrac{\rm m}{\rm s}\right) t - \left(5\dfrac{\rm m}{\mathrm s^3}\right) t^3\)

\(y(t) = 19\,\mathrm m + \left(3\dfrac{\rm m}{\rm s}\right) t - \left(9\dfrac{\rm m}{\mathrm s^2}\right) t^2\)

The particle's position vector at time \(t\) is given by

\(\vec r(t) = x(t)\,\vec\imath + y(t)\,\vec\jmath\)

Differentiate \(\vec r\) twice to recover the velocity and acceleration vectors.

\(\vec a(t) = \dfrac{d\vec v(t)}{dt} = \dfrac{d^2\vec r}{dt^2} = x''(t)\,\vec\imath + y''(t)\,\vec\jmath \\\\ \implies \vec v(t) = \left(1\dfrac{\rm m}{\rm s} - \left(15\dfrac{\rm m}{\mathrm s^3}\right) t^2\right)\,\vec\imath + \left(3\dfrac{\rm m}{\rm s} - \left(18\dfrac{\rm m}{\mathrm s^2}\right) t\right) \,\vec\jmath \\\\ \implies \vec a(t) = -\left(30\dfrac{\rm m}{\mathrm s^3}\right)t \, \vec\imath - \left(18\dfrac{\rm m}{\mathrm s^2}\right) \,\vec\jmath\)

At \(t=1.4\,\rm s\), the particle has acceleration

\(\vec a(1.4\,\mathrm s) = \left(-42\,\vec\imath - 18\,\vec\jmath) \dfrac{\rm m}{\mathrm s^2}\)

with magnitude

\(\|\vec a(1.4\,\mathrm s)\| = \sqrt{\left(-42\dfrac{\rm m}{\mathrm s^2}\right)^2 + \left(-18\dfrac{\rm m}{\mathrm s^2}\right)^2} \approx 45.695\dfrac{\rm m}{\mathrm s^2}\)

and making an angle \(\theta\) relative to the positive \(x\)-axis such that

\(\tan(\theta) = \dfrac{-18}{-42} = \dfrac37\)

Since both components of the acceleration vector have negative sign, the acceleration points into the third quadrant, so that we add a multiple of 180° after taking the inverse tangent of both sides, namely

\(\theta = \tan^{-1}\left(\dfrac37\right) - 180^\circ \approx -156.801^\circ\)

Now, (a) the magnitude of the net force acting on the particle is, by Newton's second law,

\(F = (0.41\,\mathrm{kg})\|\vec a(1.4\,\mathrm s)\| \approx \boxed{18.735\,\mathrm N}\)

and (b) makes the same angle as the acceleration vector, \(\theta \approx \boxed{-156.801^\circ}\).

At this moment, its velocity vector is

\(\vec v(1.4\,\mathrm s) = \left(-28.4\vec\imath - 22.2\,\vec\jmath\right) \dfrac{\rm m}{\rm s}\)

which (c) makes an angle \(\theta\) such that

\(\tan(\theta) = \dfrac{-22.2}{-28.4} = \dfrac{111}{142}\)

This vector also points in the third quadrant, so

\(\theta = \tan^{-1}\left(\dfrac{111}{142}\right) -180^\circ \approx \boxed{-142.986^\circ}\)

Answer:

Approximately \(19.6\; {\rm m}\) (assuming that \(g = 9.81\; {\rm m\cdot s^{-2}}\) and that air resistance is negligible.)

Explanation:

Assume that the air resistance on the rock is negligible. During the descent, the acceleration \(a\) of the rock will be constant: \(a = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}\).

It is given that the descent took \(t = 2.00\; {\rm s}\). Let \(x\) denote the displacement (change in position) of the stone. Apply the SUVAT equation \(x = (1/2)\, a\, t^{2}\) to find displacement \(x\!\):

\(\begin{aligned}x &= \frac{1}{2}\, a\, t^{2} \\ &= \frac{1}{2}\, ((-9.81)\; {\rm m\cdot s^{-2}})\, (2.00\; {\rm s})^{2} \\ &\approx (-19.6)\; {\rm m}\end{aligned}\).

Note that \(x\) is negative since the water is below the initial position of the rock. Therefore, the distance to the water will be approximately \(19.6\; {\rm m}\).

Kepler's laws are fundamental principles of celestial mechanics and continue to be valid for all planets in our solar system, including the ones discovered after Kepler's era.

Kepler's laws of planetary motion are fundamental principles that describe the motion of planets around the Sun and were derived based on observational data available to Johannes Kepler during the 16th and 17th centuries. However, these laws are not limited to the six planets known in Kepler's time.

Kepler formulated three laws of planetary motion:

1. Kepler's First Law (Law of Ellipses): Planets orbit the Sun in elliptical paths, with the Sun located at one of the two foci of the ellipse. This law applies to all planets, including those discovered after Kepler's time.

2. Kepler's Second Law (Law of Equal Areas): An imaginary line connecting a planet to the Sun sweeps out equal areas in equal time intervals. This law holds for all planets, regardless of when they were discovered.

3. Kepler's Third Law (Harmonic Law): The square of a planet's orbital period is proportional to the cube of its average distance from the Sun. This law applies to all planets, both the ones known in Kepler's time and the ones discovered later.

Kepler's laws are fundamental principles of celestial mechanics and continue to be valid for all planets in our solar system, including the ones discovered after Kepler's era. They provide important insights into the motion and behavior of celestial bodies.
