Gravity influenced the formation of the solar system, with the planets orbiting the sun.
What is Gravitational Force ?Gravitational force is force of attraction between two masses. Gravitational force(F) between two bodies is directly proportion to the product of masses(m₁,m₂) of two bodies and inversely proportional to square of distance(r) between them. mathematically it is written as,
F [tex]\alpha[/tex] m₁.m₂
F [tex]\alpha[/tex] 1/r²
F = G m₁,m₂÷r²
where G is gravitational constant, whose value is 6.6743 × 10⁻¹¹ m³ kg-1s⁻².
Force is expressed in Newton N in SI unit. its dimensions are [M¹L¹T⁻²].
According to Kepler's first law of motion, every planet is moving in an elliptical orbit with sun has situated at one of the foci of the orbit.
when a planet moves in the orbit around the sun, it moves in a stable orbit. in this orbit , centripetal force is equal to centrifugal force, in this case centripetal force appears as gravitational force. Means Gravitational force between sun and planet balances the centrifugal force which is outwards. In such a way gravity influenced the formation of the solar system.
Hence gravity plays crucial role in the formation of solar system.

Use what you have learned in the reading to answer the following question. The point of a compass needle points to Earth’s north pole. The point in the compass needle has–
~the same polarity as Earth's north pole.
~the opposite polarity from Earth’s north pole.
~no polarity.
~unlimited polarity.
The point in the compass needle has the opposite polarity from Earth’s north pole. The correct option is B.
What is a compass needle?The compass needle A magnetized pointer within a compass that can freely align with the Earth's magnetic field.
The magnetic needle is the most important part of the compass. It swings around the compass as you move, but the red end always points north and the white (or sometimes black) end always points south.
If you mean the geographical North Pole, the needle would point south because that is the only way to get there; more specifically, it would point south along the 112.4 degrees west longitude meridian towards the magnetic north pole at 82 degrees north, where compasses point.
Thus, the correct option is B.

If two forces are acting on an object , one is 25N west, and the other is 50N east. Calculate the net force.
Answer:
Explanation:
Since the forces are only in the x-direction, you could just add the two forces. The West is to the left, so it would be -25N with the negative sign indicating direction. The East is to the right, so that would be +50N.
50 + (-25) = 25N to the right or the positive i-hat direction

How can a volcano develop in the middle of a tectonic plate?
Answer:
Volcanoes that form away from plate boundaries are created by hotspots. A hotspot is an area in the mantle that is believed to be somewhat hotter than the surrounding material. The rising magma from the hotspot can push its way through the crust and burst out at the surface, forming a volcano.
Explanation:
Volcanoes can form in subduction zones, which are regions where tectonic plates are interacting one and plate is sinking beneath the other.
Essay about how volcanoes form.A volcano is a hill or mountain in the shape of a cone that is erected around a fissure in the surface of the earth thru which heated gases, rock fragments, and lava are released. A conical mass grows around the conduit as the solid fragments gather there, becoming progressively larger until it reaches the size of a gigantic volcanic mountain.
Explain what a volcano is.A volcano is an aperture or vent through which magma, tephra (small rocks), or steam are released onto the the planet's surface. Days, weeks, or even years might pass between outbursts of volcanoes.

The three main types of nuclear radiation are alpha, beta, and gamma
Which of the following lists these types of radiation from highest penetrating power to lowest penetrating power?
beta, alpha, gamma
beta, gamma, alpha
ОООО
O gamma, beta, alpha
O alpha, gamma, beta
The correct order of these types of radiation from highest penetrating power to lowest penetrating power is gamma, beta, and alpha. The correct option is C.
Among gamma, beta, and alpha radiation, gamma radiation has the shortest wavelength. This is because gamma radiation consists of high-energy electromagnetic waves, similar to X-rays and light, but with even shorter wavelengths.
In terms of other properties:
Alpha radiation consists of particles called alpha particles, which are helium nuclei (two protons and two neutrons) that are emitted from the nucleus of an atom during radioactive decay. Alpha particles are relatively large and heavy, and they have a positive charge. They have a short range in air and can be stopped by a piece of paper or human skin, but they can cause significant damage to living tissue if they are inhaled or ingested.
Beta radiation consists of particles called beta particles, which are high-energy electrons or positrons that are emitted from the nucleus of an atom during radioactive decay. Beta particles are smaller and lighter than alpha particles, and they have a negative charge. They have a longer range in air than alpha particles, but they can be stopped by a thin sheet of metal or plastic.
Gamma radiation, as mentioned earlier, consists of high-energy electromagnetic waves. Gamma rays are similar to X-rays but have even higher energies and shorter wavelengths. Gamma rays have the longest range in air and require dense materials, such as lead or concrete, to stop them. Gamma radiation is the most penetrating of the three types of radiation and can cause damage to living tissue if exposure is prolonged.

of the train?
Show your work ! PLEASEEEE HELPPP !!
Answer:
45
Explanation:
The average speed of the train was 5.33 meter/second.
What is speed?Speed is distance travelled by the object per unit time. Due to having no direction and only having magnitude, speed is a scalar quantity With SI unit meter/second.
Given parameters:
Distance travelled by the train is: d = 80 meters.
Time taken by the train: t = 15 seconds.
Hence, the average speed of the train =
total distance travelled/total time taken
= 80 meters/ 15 seconds.

A student wants to test the force of magnetism by placing objects on top of a piece of cardboard and then moving them with a magnet placed under the cardboard. Which items will help the student with this investigation?
Answer:
Any material that has ferromagnetic property
Explanation:
Materials such as iron, nickel or cobalt are ferromagnetic element as they behave as small magnets in the presence of moving electric charge or static magnetic field.
When an external magnetic field is applied these ferromagnetic material align in a way that they contribute to produce a stronger magnetic field in the material and remain aligned even after removal of the external magnetic field.
A wave in which the particles of the medium move up and down as the wave passes through is a transverse wave or a
a longitudinal wave
Answer:
transverse waves
Explanation:
this is because the definition of transverse waves is transverse waves are waves that travel perpendicular to the direction of the wave motion
however the definition of longitudinal waves is that longitudinal waves are waves that travel parallel to the direction of the wave motion.
so you can see the parallel means it forms compressions and rarefactions
but perpendicular means the particles will move up and down to the straight horizontal line, that's how lines are perpendicular right? ,
so the answer is transverse wave

A una temperatura de 329°K una placa de aluminio tiene un área de 15 m2, si su temperatura disminuye hasta 288°K; ¿Cuál es el valor de su área final?
Answer:
El área final de la placa de aluminio es 14.971 metros cuadrados.
Explanation:
Para pequeñas deformaciones, la expresión para la dilatación de área es la siguiente:
[tex]A_{f} = A_{o} \cdot [1+2\cdot \alpha \cdot (T_{f}-T_{o})][/tex] (1)
Donde:
[tex]A_{o}[/tex], [tex]A_{f}[/tex] - Áreas inicial y final de la placa, medidas en metros cuadrados.
[tex]\alpha[/tex] - Coeficiente de expansión lineal, medido en [tex]\frac{1}{K}[/tex].
[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Temperaturas inicial y final de la placa, medidas en Kelvin.
Si sabemos que [tex]A_{o} = 15\,m^{2}[/tex], [tex]\alpha = 23\times 10^{-6}\,\frac{1}{K}[/tex], [tex]T_{o} = 329\,K[/tex] y [tex]T_{f} = 288\,K[/tex], entonces el área final de la placa es:
[tex]A_{f} = (15\,m^{2})\cdot \left[1+2\cdot \left(23\times 10^{-6}\,\frac{1}{K} \right)\cdot (288\,K-329\,K)\right][/tex]
[tex]A_{f} = 14.971\,m^{2}[/tex]
El área final de la placa de aluminio es 14.971 metros cuadrados.
