Explanation:

Answer:

y

Explanation:

Answer:

The revolution of the earth around the sun and the tilt of the earth's axis cause the changing of the seasons.

Explanation:

The Earth's rotation causes day and night, while its revolution causes seasons. This happens due to how the rotation exposes different parts of the Earth to the sun, and how the tilt of the Earth's axis during revolution causes varying sunlight exposure.

The rotation of Earth on its axis causes day and night. This astronomical phenomenon happens because as the Earth rotates, different parts of it are exposed to the Sun's light, creating the cycle of day and night. On the other hand, the revolution of the Earth around the sun causes the seasons. As the Earth orbits the Sun, the tilt of our planet's axis causes different parts of the Earth to receive varying degrees of sunlight throughout the year, which results in the changes in weather conditions we know as seasons.

Answer:

The gas enclosed in a container with rigid walls is at a pressure of 150,000 Pa. The temperature of the gas is 27 ° C. At what temperature in Kelvin and degrees Celcius does the gas have to be heated so that the pressure is 300,000 Pa?

Explanation:

Given that,

When the temperature is 27°C, it's pressure is 150,000 Pa

Then,

T₁ = 27°C

Let convert to Melvin

T₁ = 27 + 273 = 300K

P₁ = 150,000 Pa

What's the temperature when it is heated to a pressure of 300,000 Pa

T₂ =?

P₂ = 300,000 Pa

Since the gas is in a rigid wall container then the volume does not change so,

V₁ = V₂

Using Gay Lussac law,

P₁ / T₁ = P₂ / T₂

Making T₂ subject of formula

T₂ = P₂ × T₁ / P₁

T₂ = 300,000 × 300 / 150,000

T₂ = 600K

So, converting to °C

°C = K - 273

°C = 600 - 273

°C = 327 °C

Then, the final temperature at 300,000 Pa is 600K OR 327°C

So, using Spanish

Dado que,

Cuando la temperatura es de 27 ° C, su presión es de 150,000 Pa

Entonces,

T₁ = 27 ° C

Deje convertir a Melvin

T₁ = 27 + 273 = 300K

P₁ = 150,000 Pa

¿Cuál es la temperatura cuando se calienta a una presión de 300,000 Pa?

T₂ =?

P₂ = 300,000 Pa

Como el gas está en un contenedor de pared rígido, el volumen no cambia,

V₁ = V₂

Usando la ley Gay Lussac,

P₁ / T₁ = P₂ / T₂

Hacer T₂ sujeto de fórmula

T₂ = P₂ × T₁ / P₁

T₂ = 300,000 × 300 / 150,000

T₂ = 600K

Entonces, convirtiendo a ° C

° C = K - 273

° C = 600 - 273

° C = 327 ° C

Entonces, la temperatura final a 300,000 Pa es 600K o 327 ° C

Answer:

A) Light waves are restricted to a single plane through the lens.

Explanation:

Took the quiz and got it right

Final answer:

The view inside a lens differs from the outside because light waves refract in multiple directions within the lens, a process essential for lenses to form images by bending light.

Explanation:

The view within the rectangle lens is different than the view outside the lens because light waves refract in multiple directions through the lens. When light waves enter the lens, they experience refraction both when they enter and exit the lens medium. The concept of refraction is inherently three-dimensional and is based on the principle that when light passes through variations in matter, its direction changes due to the different speeds at which light travels in different media. This bending of light is essential for lenses to redirect light and form images, whether they are magnified, shrunk, or inverted.

Lenses like the eye's crystalline lens or a microscope's glass lens use refraction to form images by bending light towards or away from the line perpendicular to the boundary surface. The thin lens approximation simplifies this process by considering the double refraction through the lens as a single change in path occurring at the plane of the lens. An example of this principle in action would be rays of light entering a diverging lens and appearing to originate from its focal point due to their diverging paths.

The interstellar matter within the Milky Way galaxy primarily contributes to the formation of new stars, not new galaxies, new universes, or new constellations. Constellations are not formed but are simply patterns or configurations of stars as observed from the Earth.

The Milky Way galaxy, which is the galaxy that contains our solar system, is composed of various forms of interstellar matter that include stars, dust, and gas. This interstellar matter has the potential to contribute to the formation of new celestial bodies. Forming new galaxies or new universes as suggested in the question, however, is not typically attributed to the interstellar matter within the Milky Way itself.

Instead, the interstellar matter in the Milky Way is primarily involved in forming new stars. This occurs when dense regions of dust and gas collapse under their own gravitational pull, thus initiating nuclear fusion and creating a new star.

Final answer:

Pictures of valleys on a planet's surface can indicate the presence of water, a critical natural resource, whereas other features like craters or rocks might suggest different geological aspects but not specific resources.

Explanation:

When considering pictures of a planet's surface to provide evidence about the planet's natural resources, there are specific indicators to look for. For instance, valleys often signify past or present water flow, as they are typically formed by this process. Figure 10.30 from Gale Crater and Underground Ice Deposits demonstrates this, showing cross-bedded sandstone, which geologists interpret as evidence of liquid water activity. Therefore, valleys on a planet's surface can indicate the presence of water, which is a crucial natural resource. Other features, such as craters or rocks, may suggest geological activity, age, or the presence of minerals, but not necessarily specific resources like gold or natural gas without additional data.

Answer:

[tex]|M_y| = 170.82 \ N.mm[/tex]

Explanation:

From the diagram affixed below completes the question

Now from the diagram; We need to resolve the force at point  A into (3) components ; i.e x.y. & z directions which are equivalent to [tex]F_x \ , F_y \ , F_z[/tex]

So;

[tex]F_x[/tex] = positive x axis

[tex]F_y =[/tex] Negative y axis

[tex]F_z[/tex] = positive z axis

Then;

[tex]|M_x| = F_y *27-F_z*11 = 77 ----- equation(1) \\ \\ |M_z| = F_y*4 - F_x*11 = 81 ---- equation (2) \\ \\ |M_y| = F_x *27 - F_z *4 = ? ---- equation (3)[/tex]

From equation (1); Let's make [tex]F_y[/tex] the subject of the formula ; then :

[tex]F_y = \frac{77+11F_z}{27}[/tex]

Substituting  the value for [tex]F_y[/tex] into equation (2) ; we have:

[tex](\frac{77+11F_z}{27})4-F_x*11=81 \\ \\ 11(\frac{7+F_z}{27} ) 4- F_x -11 =81 \\ \\ 28+4 F_z - 27F_x = \frac{81*27}{11} \\ \\ 4F_z - 27F_x = 198.82 -28 \\ \\ 4F_z - 27F_x = 170.82 \\ \\ Since \ |M_y| = 4F_z-27F_x \\ \\ Then: \\ \\ \\ |M_y| = 170.82 \ N.mm[/tex]

Thermoelectric generator is the method by which an electrical potential developed in generators and thermocouple.

Explanation:

Answer:

Electric generators develop an electric potential via magnetic induction. Moving a conducting rod through a magnetic field that exists between the poles of a horseshoe magnet causes an electric potential to be set up in the rod. Free electrons move through this rod from one end to the other for as long as movement of the rod is maintained. The direction of this movement depends on whether the rod is moved across the lines of force in the magnetic field in either the opposite direction or the same direction. Generators usually consist of multiple conductors mounted on a cylinder that rotates in a magnetic field.

Thermocouples utilize heat to develop an electric potential. Two strips of different metals are connected at one end to form a junction and the other ends are kept apart. A heat source is applied to the junction; this causes each metal strip’s temperature to rise at the junction. The free ends aren’t as hot and electric charges are produced at these free ends. Because the strips consist of different materials, there's a difference of potential between these free ends; when connected by a conducting wire, the electrons can move through the pathway. The voltage that's produced will become greater as the difference in temperature between the free ends and the junction increases.

Explanation:

help this help! :)

Among the options provided, both magnetic force and electric force are examples of field forces. Thus, option 1 and 2 is correct.

Magnetic force arises due to the interaction between moving charges or magnetic dipoles in a magnetic field. It is responsible for phenomena such as the attraction or repulsion between magnets, the operation of electric motors, and the behavior of charged particles moving through magnetic fields. Magnetic fields are produced by moving charges or currents, creating a force that acts on other moving charges within the field.

Electric force, similarly, arises from the interaction between charged particles within an electric field. This force is responsible for the attraction or repulsion between charged objects, the operation of devices like capacitors, and the behavior of charged particles in electric fields. Electric fields are created by static charges or changing magnetic fields, exerting a force on other charged particles within the field.

Both magnetic and electric forces are examples of field forces because they are transmitted through fields (magnetic or electric fields, respectively) and act at a distance without direct contact between the interacting objects. Conversely, normal force and gravitational force are contact forces, as they require physical contact between objects to manifest.

Answer:

Explanation:

Based on the wave model of light, physicists predicted that increasing light amplitude would increase the kinetic energy of emitted photoelectrons, while increasing the frequency would increase measured current.

Contrary to the predictions, experiments showed that increasing the light frequency increased the kinetic energy of the photoelectrons, and increasing the light amplitude increased the current.

Based on these findings, Einstein proposed that light behaved like a stream of particles called photons with an energy of \text{E}=h\nuE=hνstart text, E, end text, equals, h, \nu.

The work function, \PhiΦ\Phi, is the minimum amount of energy required to induce photoemission of electrons from a metal surface, and the value of \PhiΦ\Phi depends on the metal.

The energy of the incident photon must be equal to the sum of the metal's work function and the photoelectron kinetic energy:

The answer is: B.

speeds above 343 m/s.

:)

Supersonic speeds is speed which is above 343. Hence option B is correct.

Speed is a rate of change of distance with respect to time. i.e. v=dx÷dt. Speed can also be defined as distance over time i.e. speed= distance ÷ time. It is denoted by v and its SI unit is m/s. it is a scalar quantity. Speed shows how much distance can be traveled in unit time.

To find dimension for speed is,

from formula Speed = Distance ÷ Time

Dimension for distance is [L¹] ,

Dimension for Time is [T¹],

Dividing dimension of distance by dimension of time gives,

[L¹] ÷ [T¹] = [L¹T⁻¹]

Dimension for speed is [L¹T⁻¹].

Supersonic speed is the speed of an object that is above the speed of sound. For objects traveling in dry air of a temperature of 20 °C. Speed of the sound is 343 m/s in dry air.

Hence Option B is correct.
