Explanation:

The linear distance Δ between the ninth order maximum and the fourth order maximum on the screen is 729.6 mm.

Use formula Δ = L * (y9 - y4).

where L is the distance between the double gashes and the screen, and y9 and y4 are the distances between the centre  outside and the ninth and fourth order maxes.

 To get y9 and y4, we may use the maximum position formula in a double- slit  hindrance pattern

 y =  m * λ * L/ d  

where m is the loftiest order, is the light wavelength, L is the distance between the double gashes and the screen, and d is the slit distance.   With the  handed values, we get

d = 0.100 mm = 0.0001 m

λ = 552 nm = 0.000552 m

L = 49.0 cm = 0.49 m

m = 9

y9 = m * λ * L / d = 9 * 0.000552 * 0.49 / 0.0001 = 2.6876 m

Δ = L * (y9 - y4) = 0.49 * (2.6876 - 1.2056) = 0.7296 m

Δ = 729.6 mm

R = 24 cm

Explanation:

Given that,

A spherical mirror used in solar furnace focuses sunlight on its principal axis at a distance 12 cm from its pole. It means the focal length of the mirror is equal to 12 cm

We need to find the radius of curvature of the mirror. Let it is R. We know that the relation between radius of curvature and the focal length is given by :

R = 2f

So,

\(R=2\times 12\\\\=24\ cm\)

So, the radius of curvature of the mirror is equal to 24 cm.

The mole fractions of hydrogen and nitrogen in the vessel are\(0.6667\) and \(0.3333\), respectively. The partial pressures of hydrogen and nitrogen are\(2.00 atm\) and \(1.00 atm\) , respectively.

To calculate the mole fractions of each component, we need to determine the total moles of gas present in the vessel. Since the vessel contains \(2.0 mol\) of hydrogen and \(1.0 mol\)  of nitrogen, the total moles of gas is \(3.0 mol (2.0 mol + 1.0 mol)\). The mole fraction of hydrogen can be calculated by dividing the moles of hydrogen by the total moles of gas: \(2.0 mol / 3.0 mol = 0.6667\)  Similarly, the mole fraction of nitrogen is \(1.0 mol / 3.0 mol = 0.3333.\)

The partial pressure of a gas component is given by the product of its mole fraction and the total pressure of the system. Since the vessel contains only hydrogen and nitrogen, the total pressure is equal to the sum of their partial pressures. The total pressure can be assumed to be 1 atmosphere (atm) at \(273.15 K\) . Therefore, the partial pressure of hydrogen is \(0.6667\)  (mole fraction) multiplied by\(1 atm = 0.6667 atm.\) . Similarly, the partial pressure of nitrogen is 0.3333 (mole fraction) multiplied by\(1 atm = 0.3333 atm.\)

In summary, the mole fractions of hydrogen and nitrogen in the vessel are 0.6667 and 0.3333, respectively. The partial pressures of hydrogen and nitrogen are 2.00 atm and 1.00 atm, respectively.

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 magnetic force exerted on a 2.35m length of wire carrying a current of 0.819A perpendicular to the magnetic field of 0.920 T is 1.807 N.

The magnetic force is the force that acts between two magnets or between a magnet and a magnetic material. When a moving charge is exposed to a magnetic field, it experiences a magnetic force. The direction of the magnetic force is perpendicular to both the magnetic field and the direction of the motion of the charged particle.

The magnetic force is given by:

F = BILsin(θ)

where,

F is the magnetic force

B is the magnetic field

I is the current

L is the length of the wire

θ is the angle between the current and the magnetic field.

The length of the wire (L) is 2.35 m

The current (I) is 0.819 A

The magnetic field (B) is 0.920 T

As the wire is carrying the current perpendicular to the magnetic field, the angle between the current and the magnetic field is 90°.

Hence, the magnetic force (F) is given by:

F = BILsin(θ)

F = 0.920 T × 2.35 m × 0.819 A × sin 90°F = 1.807 N

Therefore, the magnetic force exerted on a 2.35 m length of wire carrying a current of 0.819 A perpendicular to the magnetic field of 0.920 T is 1.807 N.

The human capacity for storing long-term memories is A) essentially limitless.

The human capacity for storing long-term memories is generally considered to be essentially limitless. Unlike short-term memory, which has limited capacity and duration, long-term memory has the potential to store an enormous amount of information for extended periods.

Research suggests that the brain has an incredible capacity to form and store memories, and this capacity is not fixed or finite. The exact capacity of long-term memory is difficult to quantify precisely, as it can vary greatly among individuals and is influenced by various factors such as age, cognitive abilities, and expertise in specific domains.

While it is true that short-term memory has a limited capacity, long-term memory has the ability to store a vast amount of information over a lifetime. Studies have shown that individuals can retain an extensive range of memories, including personal experiences, factual knowledge, and learned skills, without any predetermined upper limit on storage capacity.

In astronomy, as in other fields of science, wavelength and frequency are two important properties of electromagnetic radiation. The relationship between wavelength and frequency can be described by the formula:

c = λν

where c is the speed of light, λ is the wavelength, and ν (nu) is the frequency. This formula states that the speed of light is equal to the product of the wavelength and the frequency.

In general, shorter wavelengths correspond to higher frequencies and longer wavelengths correspond to lower frequencies. This relationship is known as the inverse relationship between wavelength and frequency. For example, gamma rays have the shortest wavelengths and highest frequencies, while radio waves have the longest wavelengths and lowest frequencies.

In astronomy, this relationship is important for understanding the properties of various types of electromagnetic radiation emitted by celestial objects, such as stars, galaxies, and black holes. By measuring the wavelengths and frequencies of this radiation, astronomers can learn about the physical properties and processes occurring in these objects.

The maximum work that can be produced per unit of heat that the engine receives from the source is 0.4891.

The maximum work that can be produced by a heat engine is given by the difference between the heat received from the source and the heat rejected to the sink, which is also known as Carnot’s theorem1. The maximum work that can be obtained from a heat engine operating between two thermal-energy reservoirs at temperatures T1 and T2 (T1 > T2) is given by:

\(W_{max}\) = \(Q_{h}\) \((1 - T_{c} / T_{h} )\)

where \(Q_{h}\) is the heat absorbed from the hot reservoir at temperature \(T_{h}\) and \(T_{c}\) is the temperature of the cold reservoir.

In this case, we have:

\(T_{h}\) = 1400 r and \(T_{c}\) = 490 r

Converting these temperatures to Kelvin scale:

T_h = 1400 + 459.67

= 1859.67 K

Also, T_c = 490 + 459.67

= 949.67 K

Therefore,

\(W_{max} = Q_{h} (1 - T_{c} / T_{h} )\)

Since these three vehicles would all go the same speed at the bottom if released from the same height, they would not all possess the same amount of kinetic energy because they have different amounts of potential energy.

Kinetic energy is dependent on the velocity of the object as well as its mass. Therefore, the three vehicles, though they have the same speed, would differ in their kinetic energy due to their varying mass. This concept is known as mechanical energy and is the sum of kinetic and potential energy.

Mechanical energy is also constant in an ideal situation where no external forces are acting upon the object. For instance, the three vehicles will all have the same mechanical energy at the release point but would not possess the same amount of kinetic energy due to their mass difference.
