The angle θ is approximately 0.688°, and the angle θ' is approximately 1.988°.

To determine the angles θ and θ' in the given scenario, we can use Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the media involved. Snell's Law can be stated as follows:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Where:

n₁ is the refractive index of the medium of incidence (in this case, air with a refractive index close to 1),

θ₁ is the angle of incidence,

n₂ is the refractive index of the medium of refraction (in this case, linseed oil with a refractive index of 1.48), and

θ₂ is the angle of refraction.

Let's solve for the unknown angles θ and θ' using the given information.

Given:

Angle of incidence θ = 1°

Refractive index of linseed oil n₂ = 1.48

We need to find the angle of refraction θ₂.

Using Snell's Law, we have:

n₁ * sin(θ₁) = n₂ * sin(θ₂)

Since the refractive index of air (n₁) is approximately 1, we can simplify the equation to:

sin(θ₁) = n₂ * sin(θ₂)

Plugging in the values:

sin(1°) = 1.48 * sin(θ₂)

We can now solve for θ₂:

θ₂ = arcsin(sin(1°) / 1.48)

Calculating this value, we find:

θ₂ ≈ 0.688°

Now, let's determine the angle θ'.

Given:

Angle of refraction θ₂ = 0.688°

Refractive index of linseed oil n₂ = 1.48

We need to find the angle of incidence θ'.

Using Snell's Law, we have:

n₂ * sin(θ₂) = n₁ * sin(θ')

Since the refractive index of air (n₁) is approximately 1, we can simplify the equation to:

n₂ * sin(θ₂) = sin(θ')

Plugging in the values:

1.48 * sin(0.688°) = sin(θ')

Solving for θ', we find:

θ' = arcsin(1.48 * sin(0.688°))

Calculating this value, we get:

θ' ≈ 1.988°

Therefore, the angle θ is approximately 0.688°, and the angle θ' is approximately 1.988°.

Explanation:

Particle moving in a circular path with a constant speed.

From the calculation, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude

VELOCITY AND ACCELERATION

The rate of change of displacement is called Velocity. While acceleration is the rate of change of velocity.

Given that  a race Car A accelerates on a straight track from 0 to 100 kilometers/second in 6 seconds.

Since acceleration = \(\frac{Change in velocity}{time taken} \)

a = 1000(100 - 0)/6

a = 100000/6

a = 16666.67 m/\(s^{2} \)

And race Car B accelerates on a straight track from 0 to 100 kilometers/second in 5 seconds.

acceleration =  \(\frac{Change in velocity}{time taken} \)

a = 1000(100 - 0)/5

a = 100000/5

a = 20000 m/\(s^{2} \)

From the calculation above, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude.

Race car A accelerates at 16666.67 m/\(s^{2} \), while race car B accelerates at 20000 m/\(s^{2} \)

4)m=f÷a

=45÷15=3kg

The acceleration of the particle after 1 minute is \(18 units/min^2.\)

To find the acceleration, we need to differentiate the position function twice with respect to time.

Given:

\(s(t) = 2t^3 + 3t^2 + t\)

To find the velocity, differentiate s(t) with respect to t:

\(v(t) = d/dt [2t^3 + 3t^2 + t]\)

\(v(t) = 6t^2 + 6t + 1\)

To find the acceleration, differentiate v(t) with respect to t:

\(a(t) = d/dt [6t^2 + 6t + 1]\)

\(a(t) = 12t + 6\)

Now, substitute t = 1 to find the acceleration after 1 minute:

\(a(1) = 12(1) + 6\)

\(= 12 + 6\)

\(= 18\)

Therefore, the acceleration after 1 minute is \(18 units/min^2\)

The correct unit used to measure the electric potential difference is Volts.

Joules is used to measure energy.

Newtons is used to measure forces.

Centimeters is used to measure distance.

Therefore the correct option is the first one.

When switching from red to blue light in a laser, the fringes in the interference pattern become closer together. This phenomenon is due to the change in the wavelength of the light.

The fringe spacing in an interference pattern is directly related to the wavelength of the light used. Blue light has a shorter wavelength compared to red light. As the wavelength decreases, the fringes become denser and closer together. This means that there will be more bright spots in a given distance.

The interference pattern is created when two coherent light waves interfere constructively or destructively. Constructive interference produces bright fringes, while destructive interference creates dark fringes. As the wavelength changes, the path length difference between the interfering waves also changes, altering the interference pattern.

Switching from red to blue light effectively reduces the wavelength, causing the fringes to be closer and more numerous. This change in fringe spacing is a result of the different wave properties associated with the two colors of light and can be observed in experiments involving interferometers or other interference-based setups.

The raw file size for a 320x240 12-bit thermal image is 115,200 bytes. Thermal images have smaller raw file sizes than digital camera images because they have lower resolution and color depth, resulting in less data being stored.

(i) To calculate the raw file size for a 320x240 12-bit thermal image, we need to consider the number of pixels and the bit depth. Each pixel in a 12-bit image can have 2¹² (4096) possible values.

The total number of pixels in a 320x240 image is 76,800 (320 x 240). Multiplying this by the bit depth, we get:

76,800 pixels x 12 bits/pixel = 921,600 bits

To convert this to bytes, we divide by 8:

921,600 bits / 8 = 115,200 bytes

Therefore, the raw file size for a 320x240 12-bit thermal image is 115,200 bytes.

(ii) The file size of a thermal image compared to a typical commercial digital camera image for the visible range is generally smaller due to a couple of reasons:

1. Resolution: Thermal images typically have lower resolution compared to commercial digital camera images. The example given is a 320x240 image.

While commercial digital cameras often capture images with higher resolutions like 12 megapixels (e.g., 4000x3000 pixels). The higher-resolution images from digital cameras contain more data per image, resulting in larger file sizes.

2. Color Depth: Thermal images are often grayscale or have limited color palettes. They usually use a lower bit depth, such as 12 bits, to represent the temperature variations.

In contrast, commercial digital cameras capture images with higher color depth, such as 24 bits (8 bits per color channel), resulting in more information per pixel and larger file sizes.

In conclusion, the raw file size of a thermal image is generally smaller compared to a typical commercial digital camera image due to lower resolution and color depth, resulting in less data being stored for each image.

Explanation:

The average value of the square wave is zero, and the RMS value is 4.24 V.

The average value and RMS value calculations of square signal of 6 Vpp at 20 Hz frequency are discussed below:

Average value: The average value of any waveform is defined as the area under the curve divided by the time period. The square wave has an equal area above and below the zero line. Thus, the average value is zero.

RMS value: The RMS value of a waveform is defined as the square root of the average of the square of the waveform. Since the square wave alternates between 6 V and -6 V, it can be treated as the sum of a series of positive pulses. Thus, the RMS value of the square wave can be calculated as follows:

RMS = Vp / √2

Where Vp is the peak voltage of the waveform.

RMS = 6 / √2 = 4.24 V

Therefore, the RMS value of the square wave is 4.24 V.

"a) Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form.

b) Electric field lines are an excellent way of visualising electric fields. A field line is drawn tangentially to the net at a point.  

c) At positive charge, field lines originate and at negative charge field lines terminate.

The ratio of force on the proton to the force on electron when proton and electron are released from rest in the centre of a capacitor is equal to one.

The ratio of acceleration on the proton to electron is less than one."

The electric force per unit charge is another name for an electric field. Always pointing away from a positive charge and in the direction of a negative spot are electric field lines. Field boundaries never overlap.

Force can be written as the product of charge and electric field. The ratio of force on proton and the force and electron is,

Fp/Fe = Q× Ep/Q×Ee

where,

Q is charge

As charge and electric field are the same in both cases,

Fp/Fe = 1

As we know from Newton's second law,

F = m a = charge × electric field

⇒ ap = Q × Ep/mp

where,

ap is acceleration of proton

mp is mass of proton

Ep is electric field of proton

⇒ ae = Q × Ee/me

where,

ae is acceleration of electron

me is mass of electron

The 10-20 rule is a rule of thumb which states that the diameter of a crater formed by an impact event is roughly 10 times the diameter of the impacting object.

Object is a physical, tangible thing that can be seen and touched. It is an entity that has a physical presence in the real world. It can be an animal, a plant, a person, a place, an inanimate object, an idea, or any combination of these. Objects can also be abstract, such as an event or a concept. Object-oriented programming is a popular programming paradigm that is based on objects and their interactions. It involves creating classes, which are similar to blueprints, and then instantiating objects based on those classes.

Using this rule, the lower bound on the diameter of the resulting crater would be 10 km, assuming the diameter of the impacting object is 1 km. It is important to note, however, that this 10-20 rule is an approximation and that there are many factors that can affect the diameter of the resulting crater. For example, the angle of the impact, the angle of the surface of the target material, and the speed of the impacting object can all have an effect on the final crater size.

Answer:

Gamma rays cannot be seen or felt, but can cause ionization.

Explanation:

Gamma rays are a type of electromagnetic radiation, similar to X-rays, radio waves, and visible light. They have the highest energy and the shortest wavelength in the electromagnetic spectrum. Gamma rays are emitted by the nuclei of atoms during certain types of radioactive decay.

Gamma rays cannot be seen or felt because they are electromagnetic waves, and not particles like visible light or sound waves. Gamma rays do not have enough energy to excite the atoms in our eyes, so we cannot see them. They also do not have enough energy to cause vibrations in our ears, so we cannot hear them.

Gamma rays can cause ionization when they interact with matter, meaning that they can knock electrons off atoms and molecules, creating ions. When gamma rays pass through matter, they can disrupt the electrons in atoms and molecules, which can cause damage to living cells and genetic material. This is why gamma rays are considered to be dangerous and are used in very limited circumstances, such as in cancer treatment, where the goal is to destroy cancer cells.

Explanation:

The spring's potential energy decreases as the spring compresses, and the external force that compresses the spring does negative work.

When you stretch a spring, the work done by the external force that stretches the spring is positive. This statement is true. Explanation: The work done by an external force on an object is the product of the force applied and the distance over which it is applied. It may be either positive or negative. A spring is a flexible, elastic object that can store energy in the form of mechanical energy when compressed or stretched. Springs are frequently used to apply force or store energy in mechanical systems, making them an essential component of engineering designs. When a spring is stretched, the energy stored within it is increased. This is because the external force applied stretches the spring, which in turn stores energy in the form of potential energy, which is proportional to the spring's extension. Thus, the work done by the external force in stretching the spring is positive. However, if you compress a spring, the work done on the spring is negative.
