*The product of photosynthesis is B) glucose because it makes glucose from the plant.

The products of photosynthesis are Glucose, Oxygen and water. Since oxygen and water exit through stomata, the main product is Glucose.

Answer: Option B

Explanation:

The solar energy is utilized to produce sugar in the process of photosynthesis. This process occurs in plants, bacteria's and protistans. In the photosynthesis process, the sunlight energy is transformed into some usable chemical energy. It is possible due to the pigment called chlorophyll which is green in color and present in plants.  

Most time photosynthesis process makes use of water and releases oxygen as output. The leaves of the plants are the collector of solar. The intakes of photosynthesis process are carbon dioxide, water and the results are glucose and oxygen.

Answer:

35.7 mW

Explanation:

The intensity of light after passing through a polarizer is given by

[tex]I=I_0 cos^2 \theta[/tex]

where

[tex]I_0[/tex] is the initial intensity of the light

[tex]\theta[/tex] is the angle between the direction of polarization of the initial light and the transmission axis of the polarizing filter

Keeping in mind that the power is directly proportional to the intensity:

[tex]P \propto I[/tex]

we can rewrite the previous equation as

[tex]P=P_0 cos^2 \theta[/tex]

where we have

[tex]P_0 = 200 mW[/tex]

[tex]\theta=90^{\circ}-25^{\circ}=65^{\circ}[/tex] (because the initial light is horizontally polarized, while the axis of the filter is 25 degrees from the vertical

So, the power of the laser beam emerging from the filter is

[tex]P=(200 mW) cos^2 65^{\circ}=35.7 mW[/tex]

The power of the laser beam as it emerges from the polarizer is approximately 35.7 mW, as calculated using Malus's Law.

The power P' of a light beam after passing through a polarizer can be determined by Malus's Law:

where P is the initial power of the light, θ is the angle between the light's initial polarization direction and the axis of the polarizer.

In this case, the light is horizontally polarized and the axis of the polarizer is 25° from vertical, so the angle θ we need is the complement of 25°, which is 65° (since 90° - 25° = 65°).

Plug in the given values: P = 200 mW and θ = 65° into the equation, we get:

Solving this you get: P' = 35.7 mW

If we are talking about simple harmonic motion, we are talking about waves and in this case the frequency [tex]f[/tex] is related to the period of oscillation [tex]T[/tex] in an inverse proportion.

Now, for a mass-on-a-spring system the period is given by:

Where [tex]m[/tex] is the oscillating mass and [tex]k[/tex] the spring constant, which depends on the spring stillness.

As we can see in this equation:

If we change [tex]m[/tex] and [tex]k[/tex] we will affect the period, hence the frequency.

Nevertheless, we do not see any relation with the Amplitude, this means the period (hence the frequency) does not depend on the amplitude.

Explanation:

A) [tex]E(r) = \frac{\rho r_b^3}{3 \epsilon_0 r^2}[/tex]

In this problem we have spherical symmetry, so we can apply Gauss theorem to find the magnitude of the electric field:

[tex]\int E(r) \cdot dr = \frac{q}{\epsilon_0}[/tex]

where the term on the left is the flux of the electric field through the gaussian surface, and q is the charge contained in the surface.

Here we are analyzing the field at a distance [tex]r>r_B[/tex], so outside the solid ball. If we take a gaussian sphere with radius r, we can rewrite the equation above as:

[tex]E(r) \cdot 4 \pi r^2 = \frac{q}{\epsilon_0}[/tex] (1)

where [tex]4 \pi r^2[/tex] is the surface of the sphere.

The charge contained in the sphere, q, is equal to the charge density [tex]\rho[/tex] times the volume of the solid ball, [tex]\frac{4}{3}\pi r_b^3[/tex]:

[tex]q= \rho (\frac{4}{3}\pi r_b^3)[/tex] (2)

Combining (1) and (2), we find

[tex]E(r) \cdot 4 \pi r^2 = \frac{4\rho \pi r_b^3}{3 \epsilon_0}\\E(r) = \frac{\rho r_b^3}{3 \epsilon_0 r^2}[/tex]

And we see that the electric field strength is inversely proportional to the square of the distance, r.

B) [tex]\frac{\rho r}{3 \epsilon_0}[/tex]

Now we are inside the solid ball: [tex]r<r_B[/tex]. By taking a gaussian sphere with radius r, the Gauss theorem becomes

[tex]E(r) \cdot 4 \pi r^2 = \frac{q}{\epsilon_0}[/tex] (1)

But this time, the charge q is only the charge inside the gaussian sphere of radius r, so

[tex]q= \rho (\frac{4}{3}\pi r^3)[/tex] (2)

Combining (1) and (2), we find

[tex]E(r) \cdot 4 \pi r^2 = \frac{4\rho \pi r^3}{3 \epsilon_0}\\E(r) = \frac{\rho r}{3 \epsilon_0}[/tex]

And we see that this time the electric field strength is proportional to r.

C)

E(0)=0.

limr→∞E(r)=0.

The maximum electric field occurs when r=rb.

Explanation:

From part A) and B), we observed that

- The electric field inside the solid ball ([tex]r<r_B[/tex]) is

[tex]\frac{\rho r}{3 \epsilon_0}[/tex] (1)

so it increases linearly with r

- The electric field outside the solid ball ([tex]r>r_B[/tex]) is

[tex]E(r) = \frac{\rho r_b^3}{3 \epsilon_0 r^2}[/tex] (2)

so it decreases quadratically with r

--> This implies that:

1) At r=0, the electric field is 0, because if we substitute r=0 inside eq.(1), we find E(0)=0

2) For r→∞, the electric field tends to zero as well, because according to eq.(2), the electric field strength decreases with the distance r

3) The maximum electric field occur for [tex]r=r_B[/tex], i.e. on the surface of the solid ball: in fact, for [tex]r<r_B[/tex] the electric field increases with distance, while for [tex]r>r_B[/tex] the field decreases with distance, so the maximum value of the field is for [tex]r=r_B[/tex].

The magnitude of the electric field E(r) at a distance r>rb and r from the center of a solid ball with uniform charge density can be calculated using the same formula. The electric field is zero at the center and surface of the ball, and approaches zero as r tends to infinity.

Part A:

The magnitude of the electric field E(r) at a distance r>rb from the center of the ball can be calculated using the formula:

E(r) = (ρ * (4/3) * π * rb³) / (4 * π * ϵ0 * r²)

Part B:

The magnitude of the electric field E(r) at a distance r from the center of the ball can be calculated using the formula:

E(r) = (ρ * (4/3) * π * rb³) / (4 * π * ϵ0 * r²)

Aeronautics is the science of designing planes and other flying machines. Aeronautical engineers must understand four fundamental areas in order to design planes. Engineers must understand all of these elements in order to design a plane.

A plane uses something called "air pushing it up" to help it fly. This air pushing is called "lift." The wings of the plane are shaped like long, flat feathers that help create lift.

Another way the plane flies is by using its engine to make a strong "whoosh" of air that moves the plane forward. This strong "whoosh" of air is called "thrust."

And finally, the plane uses its tail to help it steer and balance, just like a bird uses its tail to help it fly straight.

So, when all of these things work together, the big heavy piece of metal becomes a plane that can fly high up in the sky.

The correct path of light through a reflecting telescope will be Primary mirror--->secondary mirror--->eyepiece--->eye.

A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image

it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors.

Reflecting telescopes come in many design variations and may employ extra optical elements to improve image quality or place the image in a mechanically advantageous position.

A curved primary mirror is the reflector telescope's basic optical element that creates an image at the focal plane. The distance from the mirror to the focal plane is called the focal length.

Film or a digital sensor may be located here to record the image, or a secondary mirror may be added to modify the optical characteristics and/or redirect the light to film, digital sensors, or an eyepiece for visual observation.

Answer:

A virtual image is formed at the position from which the rays appear to have originated

Explanation:

When using lenses or mirrors to produce the image of an object, two types of images can be produced:

- Real image: a real image is produced when the rays of light actually converge to a point - in this case, the image can be projected on a screen. For a lens, a real image is located on the opposite side of the lens relative to the object, while for a mirror, a real image lies on the same side of the object with respect to the mirror

- Virtual image: a virtual image is formed at the position from which the rays appear to have originated. Because of that, a virtual image cannot physically be projected on a screen. For a mirror, a virtual image is located on the opposite side of the mirror relative to the object, while for a lens, a virtual image lies on the same side of the object with respect to the lens.

Answer:

[tex]2.74\cdot 10^{14} Hz[/tex]

Explanation:

First of all, let's convert the energy gap from eV to Joules:

[tex]E=1.14 eV \cdot (1.6\cdot 10^{-19}J/eV)=1.82\cdot 10^{-19}J[/tex]

In order to promote the electron to the conduction band, the electron must absorb a photon with an energy at least equal to the energy gap, so:

[tex]E=hf=1.82\cdot 10^{-19}J[/tex]

where

h is the Planck constant

f is the frequency of the photon

Solving for f, we find the lowest frequency needed:

[tex]f=\frac{E}{h}=\frac{1.82\cdot 10^{-19} J}{6.63\cdot 10^{-34}Js}=2.74\cdot 10^{14} Hz[/tex]

The lowest frequency photon that will promote an electron in silicon from the valence band to the conduction band is approximately 1.72 x 10^14 Hz.

To find the lowest frequency photon that will promote an electron in silicon from the valence band to the conduction band, we need to determine the energy difference between the two bands. The energy gap for silicon at 300 K is given as 1.14 eV. Since energy is directly proportional to frequency, we can use the equation E = hf, where E is the energy, h is Planck's constant (6.63 x 10^-34 J s), and f is the frequency. Rearranging the equation gives f = E/h. Plugging in the energy gap for silicon and Planck's constant, we can calculate the lowest frequency photon.

f = (1.14 eV) / (6.63 x 10^-34 J s) = 1.72 x 10^14 Hz

Therefore, the lowest frequency photon that will promote an electron in silicon from the valence band to the conduction band is approximately 1.72 x 10^14 Hz.

Explanation:

Radiation affects both cancer cells and healthy cells, but it affects cancer cells more.

Radiation is often used in cancer treatment because the rapid cell division of cancer cells makes them vulnerable to radiation damage. These cells often cannot repair this damage as effectively as healthy cells, leading to their destruction. However, radiation is not the only method for fighting cancer.

Radiation is often used to destroy cancer cells because, in general, cancer cells divide more rapidly than normal cells, which makes them more susceptible to the damaging effects of radiation. This is the reason behind the option (C). While radiation does affect both cancerous and healthy cells, the quick division of cancer cells often makes them more vulnerable to being damaged by the radiation. However, they often cannot repair this damage as effectively as healthy cells can. Consequently, the cancer cells are destroyed, with minimal effect on the healthy cells. It's important to note that radiation is not the only method to fight cancer as stated in option (D). Other methods include surgery, chemotherapy, and immunotherapy. Furthermore, radiation is not a tracer that picks out cancer cells to destroy as stated in option (B).

[tex]\theta[/tex] is the parallax angle, in arcseconds

For the star in the problem, the parallax angle is

[tex]2.46\cdot 10^5 J[/tex]

Explanation:

The enegy of a single photon is given by:

[tex]E=\frac{hc}{\lambda}[/tex]

where

h is the Planck costant

c is the speed of light

[tex]\lambda[/tex] is the wavelength of the photon

In this problem,

[tex]\lambda=486 nm=4.86\cdot 10^{-7}m[/tex]

so the energy of one photon is

[tex]E_1=\frac{(6.63\cdot 10^{-34} Js)(3\cdot 10^8 m/s)}{4.86\cdot 10^{-7}m}=4.09\cdot 10^{-19} J[/tex]

1 mole of photons contains a number of Avogadro of photons:

[tex]N_A = 6.022\cdot 10^{23}[/tex]

therefore, the total energy of 1 mole of these photons will be

[tex]E=N_A E_1 = (6.022\cdot 10^{23})(4.09\cdot 10^{-19} J)=2.46\cdot 10^5 J[/tex]

The energy of a mole of photons with a wavelength of 486 nm is 2.462 x 10^5 joules, calculated by applying Planck's equation and using Avogadro's number.

The energy in joules of a mole of photons associated with visible light of wavelength 486 nm can be calculated using Planck's equation, E = hc/\u03bb, where h is Planck's constant (6.626 x 10-34 J·s), c is the speed of light (3.00 x 108 m/s), and \u03bb is the wavelength of the light (486 nm or 486 x 10-9 m). To find the energy per mole of photons, we also use Avogadro's number (6.022 x 1023 photons/mole).

First, calculate the energy of one photon:

E = hc/\u03bb = (6.626 x 10-34 J·s) (3.00 x 108 m/s) / (486 x 10-9 m) = 4.09 x 10-19 J/photon

Then, calculate the energy per mole of photons:

Emole = E · Avogadro's number = 4.09 x 10-19 J/photon x 6.022 x 1023 photons/mole = 2.462 x 105 J/mole

Therefore, the energy of a mole of photons at 486 nm is 2.462 x 105 joules.

The magnitude of the triceps muscle force M needed to maintain static equilibrium of the forearm is 138 N, which balances the weight of the forearm and the force registered on the scale.

To solve for the magnitude of the force applied by the triceps muscle, M, we must take into account the principles of static equilibrium. In static equilibrium, the sum of all forces acting on the object is zero because it is not moving. Given that the forearm weighs 20.0 N, and the scale registers a downward force of 118 N, we know that there is an upward force required to balance the system and maintain equilibrium.

Let's establish an equation for the vertical forces acting on the forearm:

Since the forearm is in equilibrium, the upward force must balance the downward forces:

M = 138 N

Therefore, the magnitude of the force M applied by the triceps muscle is 138 N.
