The north part of the compass needle is attracted to the magnetic south pole of Earth, which is also known as the geographical north pole.  When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.

Explanation:

A) The 3-and y-components of the initial velocity vector are (0.7431y - 233.327 fis) and (0.6691y - 209.466 fis) respectively.

B) The maximum height reached by the arrow is (0.136y² - 85.836y + 13505.45) fis.

The horizontal component of initial velocity,

u_x = u cos θ= (y - 314 fis) cos 42°

      = (y - 314 fis) × 0.7431

      = 0.7431y - 233.327 fis.

The vertical component of initial velocity,

u_y = u sin θ= (y - 314 fis) sin 42°

      = (y - 314 fis) × 0.6691

      = 0.6691y - 209.466 fisB)

Calculate the maximum height reached.

The time taken to reach maximum height,

t = u sin θ / g

 = [(y - 314 fis) sin 42°] / 9.81

 = 0.067y - 21.019 fis.

The maximum height reached,

H = u² sin² θ / 2g

   = [(y - 314 fis)² sin² 42°] / (2 × 9.81)

   = 0.136y² - 85.836y + 13505.45 fis.

So, the 3-and y-components of the initial velocity vector are (0.7431y - 233.327 fis) and (0.6691y - 209.466 fis) respectively.The maximum height reached by the arrow is (0.136y² - 85.836y + 13505.45) fis.

The chamber has an absolute pressure of 64 kPa.

Absolute pressure is the force that exists in a space when there is no matter present, or when there is a perfect vacuum. This absolute zero serves as the baseline for measurements in absolute pressure. The measurement of barometric pressure is the greatest illustration of an absolute referenced pressure.

By deducting the ambient pressure from the vacuum gauge measurement, the absolute pressure inside the chamber can be calculated:

Atmospheric pressure minus the vacuum gauge reading gives the chamber's absolute pressure.

absolute pressure in the chamber is

=>100 kPa - 36 kPa

=> 64kPa

Therefore, 64 kPa is the chamber's absolute pressure.

Explanation:

The wave motion in a Slinky is an example of a longitudinal wave. So, option b. is correct.

In a longitudinal wave, the particles of the medium move parallel to the direction of the wave propagation. In the case of a Slinky, the coils of the spring move back and forth parallel to the direction of the wave as it travels along the length of the Slinky.

This is in contrast to a transverse wave, where the particles of the medium move perpendicular to the direction of wave propagation, such as a wave on a string.

A complex wave, on the other hand, is a combination of two or more waves with different frequencies, amplitudes, or directions of propagation.

An example of a complex wave is sound, which is a longitudinal wave that can be composed of multiple frequencies (harmonics) that give it its unique timbre.

Therefore, the correct classification for the wave motion in a Slinky is a longitudinal wave.

So, option b. is correct.

Answer:

The linear speed of the 0.0800 kg sphere as it passes through its lowest point is 0.989 m/s.

Explanation:

To solve this problem, we can use the principle of conservation of energy, which states that the initial potential energy of the system is equal to the final kinetic energy of the system, assuming no energy is lost to friction or other non-conservative forces.

Initially, the system has only potential energy due to the height of the spheres above their lowest point. At the lowest point, all of this potential energy is converted to kinetic energy, which is shared between the two spheres. We can set the initial potential energy equal to the final kinetic energy and solve for the final speed of the 0.0800 kg sphere.

The initial potential energy of the system is given by:

U_i = mgh = (0.0200 kg)(9.81 m/s^2)(40.0 cm) + (0.0800 kg)(9.81 m/s^2)(40.0 cm) = 0.0782 J

where h is the height of the spheres above their lowest point, which is half the length of the rod.

The final kinetic energy of the system is given by:

K_f = (1/2)mv^2

where m is the mass of the 0.0800 kg sphere and v is its final speed.

Setting the initial potential energy equal to the final kinetic energy and solving for v, we get:

0.0782 J = (1/2)(0.0800 kg)v^2

v^2 = 0.97875 m^2/s^2

v = 0.989 m/s (to three significant figures)

Both lunar and solar eclipses occur due to the alignment of the Sun, Moon, and Earth, but the specific conditions required for each type of eclipse are slightly different.

For a lunar eclipse to occur, three conditions are necessary:

Full Moon: A lunar eclipse can only occur during a Full Moon when the Moon is on the opposite side of the Earth from the Sun.

Alignment: The Earth, Moon, and Sun must be aligned in a straight line, with the Earth in the middle.

Angle: The Moon's orbit around the Earth is tilted at an angle of about 5 degrees to the Earth's orbit around the Sun. Therefore, for a lunar eclipse to occur, the Moon must pass through the Earth's shadow, which only happens when the alignment is just right.

For a solar eclipse to occur, three different conditions are necessary:

New Moon: A solar eclipse can only occur during a New Moon, when the Moon is between the Earth and the Sun.

Alignment: The Earth, Moon, and Sun must be aligned in a straight line, with the Moon in the middle.

Distance: The Moon's distance from the Earth can affect whether or not a solar eclipse occurs. The Moon's orbit around the Earth is elliptical, meaning that it is not always the same distance from Earth. If the Moon is too far away, it appears smaller in the sky and cannot completely block the Sun's disk, resulting in an annular solar eclipse. If the Moon is closer to the Earth, it appears larger and can fully block the Sun, resulting in a total solar eclipse.

Energy is transferred along the food chain from the producers to the decomposers.

The term food chain has to do with the process by which energy is passed from one organism to another along the in the ecosystem. Let us recall that the ecosystem is a unit that is composed of living and non living parts and is able to sustain itself.

According to the principle of second law of thermodynamics, energy transfers is not 100% efficient. Thus as energy is transferred along the food chain, only 10% of the energy that was acquired from the pervious trophic level is passed on to the succeeding trophic level.

This is because of the fact that the remainder of the energy is utilized in the metabolic activities of organisms. We can rightly call the food chain a food cycle because as we can see from the image, energy is obtained from the sun and passed along the food chain and returned to the producers by the activities of the decomposers.

If the back of a person's eye is too close to the lens, this person is suffering from a. nearsightedness,

This is also known as myopia, nearsightedness is a common refractive error that occurs when the eye's length is longer than usual, causing light rays to focus in front of the retina instead of directly on it. As a result, people with nearsightedness can see objects up close clearly, but distant objects appear blurry. Nearsightedness is not related to spherical aberration, astigmatism, or chromatic aberration. Spherical aberration occurs when light rays entering the lens at different distances from the center do not focus at the same point, causing image distortion.

Astigmatism is another refractive error that happens when the cornea or lens has an irregular shape, resulting in blurred vision at all distances. Chromatic aberration is an optical phenomenon in which a lens cannot focus all colors of light at the same point, causing color fringes around objects. Farsightedness, or hyperopia, is the opposite of nearsightedness. In this case, the eye is shorter than normal, causing light rays to focus behind the retina, making it difficult to see nearby objects clearly. So therefore if the back of a person's eye is too close to the lens, this person is suffering from a. nearsightedness,

Answer:

 I₃ = I₀ 0.395

Explanation:

Polarized light passing through a polarizer must comply with Malus's law

         I = I₀ cos² θ

Before starting, let's analyze the angle between the polarizers, the second has the same angle with the first and the third, so it is at the midpoint

         θ₂ = 39/2 = 19.5

now let's analyze the light that passes through each polarizer, as the incident is unpolarized through the first polarizer half the intensity comes out

          I₁ = I₀ / 2

the second polarizer comes out

          I₂ = I₁ cos² 19.5

          I₂ = I₀ / 2 cos² 19.5

through the third polarized the intensity passes

          I₃ = I₂ cos² 19.5

          I₃ = (I₀ /2 cos² 19.5) cos² 19.5

          I₃ = I₀ 0.395
