The answer is False, dark nebulae are not opaque to all wavelengths of electromagnetic radiation. Dark nebulae are interstellar clouds of dust and gas that obscure the light from stars and other celestial objects behind them, primarily in the visible light spectrum.

However, they do allow certain wavelengths of electromagnetic radiation to pass through, particularly longer wavelengths such as infrared and radio waves. Observations in these wavelengths enable astronomers to study the structures and properties of dark nebulae, as well as the star formation processes occurring within them. In summary, dark nebulae are not completely opaque to all forms of electromagnetic radiation, but rather selectively absorb and scatter specific wavelengths, particularly visible light.

The given one is an experiment because it tests a cause and effect relationship. The rate of photosynthesis is determined by measuring the concentration of carbon dioxide on an enclosed transparent chamber.

Photosynthesis is a biochemical process by which green plants synthesis chemical energy with the aid of light energy. The photosynthetic reaction is  the combination of carbon dioxide and water to form oxygen molecule and glucose.

The photosynthetic reaction is given here:

\(\rm 6CO_{2} + 6H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}\)

Here, the oxygen gas is the product in the reaction. Hence, increase in the oxygen level will reverse the reaction and thus, rate of photosynthesis decreases.

The rate of photosynthesis is determined by the measurement of concentration of carbon dioxide within the closed transparent chamber in which the plant is placed. Hence, we are testing a cause and effect and it is a scientific experiment. Hence, option A is correct.

Newton's law of universal gravitation states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Newton's Law of Universal Gravitation states that every object with mass attracts every other object with mass. The force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The key equation for Newton's Law of Universal Gravitation is:
F = G * (m1 * m2) / r2.
where F is the gravitational force, G is the gravitational constant, m1, and m2 are the masses of the objects, and r is the distance between their centers.

This is a general law of physics derived from experimental observations, which Isaac Newton called inductive reasoning. It is part of classical mechanics and was developed in Newton's book Philosophiæ Naturalis Principia Mathematica ("Principles of Mathematics"), first published on July 5, 1687. When Newton presented Volume 1, he did not report to the Royal Society in April 1686. Robert Hooke claimed that Newton took the right back from him.

In modern language, the law states that each element of the group attracts all other elements of the group with a force acting along a line where the two elements intersect. The force is proportional to the product of the two groups and inversely proportional to the square of the distance between them.

Light rays first pass through the transparent layer called the cornea and then refracted again as they pass through the transparent lens.

How do light rays flow in the eyes?

The first factor in the journey of light via the eye is the objects being seen and how they produce, reflect, or change the light in various ways.

The visual cortex of the brain's occipital lobe serves as the destination of the light pathway, which starts with photoreceptors in the retina. Rod and cone cells are two different types of photoreceptors. When it comes to eyesight in low light and in peripheral vision, rods can be especially helpful.

The cornea is where most of the refraction occurs as light enters the eye's curved, transparent front surface. The natural or crystalline lens of the eye also distorts light rays. When an item passes in front of the eye, its rays pass through the transparent cornea and enter the eye.

Explanation:

The total resistance for a series is the sum of each resistance.  If both lamps are the same (same resistance, R ohms each) then the battery will sense 2R resistance.

The volume of a material is related to temperature through thermal expansion and thermal contraction. Different materials will expand and contract at different rates, and the amount of expansion or contraction also depends on the magnitude of the temperature change.

Temperature and volume are related through the phenomenon of thermal expansion and thermal contraction. Thermal expansion occurs when the temperature of a material increases, causing the material to expand or increase in volume. Thermal contraction is the opposite; when the temperature of a material decreases, the material contracts or decreases in volume.

The amount of thermal expansion or contraction that occurs depends on the type of material, as different materials will respond differently to temperature changes. Generally, solids experience more thermal expansion than liquids, and metals experience more thermal expansion than non-metals. This means that when the temperature of a material increases, the volume of a solid material will increase more than the volume of a liquid material; the volume of a metal material will increase more than the volume of a non-metal material.

The amount of thermal expansion or contraction also depends on the magnitude of the temperature change. Generally, the greater the temperature change, the greater the amount of thermal expansion or contraction. For example, if the temperature of a material is increased from 10°C to 20°C, the material may experience a small amount of thermal expansion. However, if the temperature is increased from 10°C to 100°C, the material may experience a large amount of thermal expansion.

\(\tt =24\times 9.8(2-1)=235.2~J\)

The average potential difference across the coil is: 9 × 10⁻³ volts or 9 millivolts when the magnetic field strength changes as described.

To find the average potential difference, we can use Faraday's law of electromagnetic induction, which states that the induced electromotive force (EMF) in a coil is equal to the rate of change of magnetic flux through the coil. The formula for Faraday's law is:

EMF = -N × (ΔΦ/Δt)

where EMF is the induced electromotive force, N is the number of turns in the coil, ΔΦ is the change in magnetic flux, and Δt is the time interval.

First, we need to convert the cross-sectional area from cm² to m²:

1000 cm² × (1 m / 100 cm)² = 0.1 m²

Next, we calculate the change in magnetic flux:

ΔΦ = (10^-4 Wb/m³ - 10^-3 Wb/m²) × 0.1 m² = -9 × 10⁻⁵ Wb

Now, we can plug the values into Faraday's law formula:

EMF = -100 × (-9 × 10⁻³ Wb / 0.1 s) = 9 × 10⁻³ V

Therefore, the average potential difference across the coil is 9 × 10⁻³volts or 9 millivolts when the magnetic field strength changes as described.

S = 1/2 a t^2       distance covered by falling body from speed = 0

300 = 1/2 a 10^2

a = 600 m / 100 s^2 = 6 m/s^2

v = a t = 6 m/s^2 s * 10 s = 60 m/s     speed after 10 sec

S2 = v t + 1/2 a t^2

S2 = 60 m/s * 10 sec + 3 m/s^2 * 100 s^2

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.

The moment of inertia of the odd-shaped object is: approximately 1.67x10⁻³ kg∙m².

To find the moment of inertia of the odd-shaped object, we can use the conservation of angular momentum principle. Angular momentum before the mass is dropped equals angular momentum after the mass is dropped.

Initially, only the odd-shaped object is rotating with an angular speed of 10.0 rev/s. After the 25 g mass with a moment of inertia I=1.5x10⁻⁶ kg∙m² is dropped onto the object at a distance of 4.5 cm (0.045 m) from its center of mass, the system's angular speed slows to 9.0 rev/s.

First, let's convert the angular speed from rev/s to rad/s:

Initial angular speed (ω1) = 10.0 rev/s * 2π rad/rev ≈ 62.83 rad/s
Final angular speed (ω2) = 9.0 rev/s * 2π rad/rev ≈ 56.55 rad/s

Let I_obj be the moment of inertia of the odd-shaped object. The angular momentum before and after the mass is dropped can be written as:

I_obj * ω1 = (I_obj + I + m * r²) * ω2

Solving for I_obj, we get:

I_obj = [(I + m * r²) * ω2] / ω1

Substituting the given values:

I_obj = [(1.5x10^-6 kg∙m² + (0.025 kg * (0.045 m)^2)) * 56.55 rad/s] / 62.83 rad/s

After calculating the above expression, we find that the moment of inertia of the odd-shaped object is approximately 1.67x10⁻³ kg∙m².

The Pressure Gradient Force (PGF) is the force that drives air from areas of high pressure to areas of low pressure. In both a trough and a ridge, the PGF is the same.

However, the winds will not be the same in both features.  

In a trough, the winds tend to move towards the center of the trough, where the air is rising, and this causes convergence and lifting. This upward motion causes a decrease in pressure, leading to a steeper pressure gradient, which means stronger winds. On the other hand, in a ridge, the winds move away from the center of the ridge, where the air is sinking, and this causes divergence and sinking. This sinking motion causes an increase in pressure, leading to a weaker pressure gradient and lighter winds.  

Therefore, assuming the same PGF, the trough will have the faster winds compared to the ridge.

The CG is located 99.76 inches aft of the datum.

To determine center of gravity (CG), we need to use formula:

CG = (Σ(weight x arm))/Σ(weight)

where Σ(weight x arm) is sum of  weight times arm for each component, and Σ(weight) is sum of all weights.

Weight of pilot and passengers = 380.0 lb

Arm of pilot and passengers = 64.0 in

Weight of fuel = total weight - empty weight - weight of pilot and passengers = 1875.0 - 1495.0 - 380.0 = 0 lb

Arm of fuel = 96.0 in

Calculate the CG:

CG = (1495.0 x 101.4) + (380.0 x 64.0) + (0 x 96.0) / (1495.0 + 380.0 + 0) = 99.76 in aft of datum

                                                            = 35 x 4

                                                            = 140 Newton-meters

2. Work done, W  = 420 Nm

   Time, T = 3 seconds

   Therefore, the power required is,

   \($P=\frac{W}{T}$\)

   \($P=\frac{420}{3}$\)

       = 140 joules

3. The force exerted is, F = 1.2 N

  Distance the box is moved, d = 5 m

  So the amount of work done is, W = F x d

                                                            = 1.2 x 5

                                                            = 6 Newton-meters

4. Work done, W  = 120 Nm

   Time, T = 20 seconds

   Therefore, the power required is,

   \($P=\frac{W}{T}$\)

   \($P=\frac{120}{20}$\)

       = 6 joules
