The new gravitational force between the two masses is 4 times the original force, or 4F.

To find the new gravitational force between the two masses when the mass M is replaced by a mass of 2M, we'll use the formula for gravitational force and plug in the appropriate values.
The gravitational force (F) between two objects with masses m1 and m2, separated by a distance (R), is given by the formula:
F = G × (m1 × m2) / R²
where G is the gravitational constant.
Initially, we have the masses M and 2M, with a force F:
F = G × (M ×2M) / R²
Now, let's replace the mass M with 2M and find the new force (F_new):
F_new = G × (2M ×2M) / R²
We can simplify this as:
F_new = 4 × G × (M × 2M) / R²
Notice that the expression G × (M × 2M) / R² is equal to the original force F:
F_new = 4 ×F
So the new gravitational force between the two masses is 4 times the original force, or 4F.

This expression gives the burning surface area A of one motor segment in terms of r1, r2, and w.

To find an expression for the burning surface area (A) of one motor segment, considering that both ends and the inner bore of the cylinder burn, we will use the terms r1, r2, and w.

The surface area A can be calculated as the sum of the areas of the two ends and the inner bore. The two ends have circular shapes, while the inner bore has a cylindrical shape.

For the ends, we have two circles with radii r1 and r2. The area of a circle is given by the formula A = πr². So, the total area of the two ends is:

A_ends = πr1² + πr2²

For the inner bore, we have a cylinder with radius r1 and height w. The lateral surface area of a cylinder is given by the formula A = 2πrh. So, the area of the inner bore is:

A_bore = 2πr1w

Now, we can find the total burning surface area A by adding the areas of the two ends and the inner bore:

A = A_ends + A_bore
A = (πr1² + πr2²) + 2πr1w

This expression gives the burning surface area A of one motor segment in terms of r1, r2, and w.

The force constant of the spring is 200.696 N/m & The height the object achieves when the spring releases its energy is 2.5087 m

The spring constant is the force needed to stretch or compress a spring, divided by the compressive or expansive distance. It's used to determine stability or instability in the spring, and therefore the system it's intended for. we know,

F = kx

Therefore,

k = F/x

We also know that the force being exerted on the spring is equal to the mass of the object. Hence, F = mg = 5.13 * 9.8 N = 50.174 N and we know compression due to the mass is 0.25m. Therefore,

K = 50.174/0.25 N/m

K = 200.696 N/m

Therefore, The Spring Constant is 200.696 N/m

On release, the spring potential energy gets converted to kinetic energy. Hence, on release, the height attained by the object is given by:

h = \(1/2 kx^{2}\)

We know that k=200.696 N/m and x=0.25 m. Therefore the height is:

h = \(1/2 (200.696 N/m)(0.25 m)^{2}\)

h = 2.5087 m

Coherence is the property by which two waves with identical wavelengths maintain a constant phase relationship.

The property of coherence refers to the relationship between two waves that have the same wavelength. Coherent waves maintain a constant phase relationship, meaning that the crests and troughs of the waves are aligned at all times. This is different from incoherent waves, which have no predictable relationship between their phases.

While the amplitude and frequency of waves can also be important properties, they are not directly related to coherence. Amplitude refers to the strength of a wave, while frequency refers to the number of cycles per second that a wave completes.

Coherent waves can be important in many areas of physics and engineering. For example, lasers are able to produce coherent light waves, which allows them to be used in a wide range of applications, from surgery to data transmission. Coherent waves can also be used in interferometry, a technique used to measure small changes in distance or position.

In summary, coherence is the property by which two waves with identical wavelengths maintain a constant phase relationship. This is important in many fields of science and technology, and is particularly useful for applications that require precise measurements or control over the behavior of waves.

The work-energy theorem is a fundamental principle in physics that relates the work done on an object to its change in kinetic energy.

The theorem states that the net work done on an object is equal to its change in kinetic energy:

Net Work = Change in Kinetic Energy

In other words, the work-energy theorem tells us that the work done on an object is equal to the change in its kinetic energy. If work is done on an object, its kinetic energy will change by an amount equal to the work done. Conversely, if the kinetic energy of an object changes, it must be due to work being done on the object.

The work-energy theorem applies to both conservative and non-conservative forces. For conservative forces, the work done depends only on the initial and final positions of the object, and not on the path taken between them.

For non-conservative forces, such as friction, the work done depends on the path taken and may result in a loss of mechanical energy.

The work-energy theorem is a powerful tool for analyzing and solving problems in physics, and it is widely used in many fields, including mechanics, thermodynamics, and electromagnetism.

It allows us to relate the work done on an object to its resulting motion and energy changes, providing a comprehensive picture of the physical system under consideration.

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.

The power cycle shown in the figure represents a type of internal combustion engine, commonly used in automobiles. It consists of four processes: intake, compression, combustion, and exhaust. During the intake process, the piston moves downward, drawing in a mixture of air and fuel. Then, during the compression process, the piston moves upward, compressing the air-fuel mixture. The compression causes an increase in temperature and pressure, which is necessary for the combustion process.

Next, during the combustion process, a spark ignites the compressed air-fuel mixture, causing it to rapidly expand and push the piston downward. This is where the engine produces power to turn the wheels of the vehicle. Finally, during the exhaust process, the piston moves upward again, pushing the burnt gases out of the cylinder.

The efficiency of this power cycle can be improved by using various techniques such as turbocharging, supercharging, and direct fuel injection. These techniques increase the amount of air and fuel entering the engine, resulting in more power output. However, they also increase the temperature and pressure inside the engine, which can cause problems such as knocking and engine damage.

Overall, the power cycle shown in the figure is an important process in internal combustion engines. It has undergone many improvements over the years, and continues to be a crucial part of transportation and many other industries.

If transformations from stabilization are minimal, a double pendulum performs basic geometric motion. The highly nonlinear system, furthermore, becomes radically unstable in its motion as significant displacements are introduced, showing that deterministic processes are not inherently predictable

A ball is launched into the air vertically. Because of air resistance, it takes less time to come down than to get up.

The forces that oppose an object's relative motion as it travels through the air are known as air resistance. These drag forces cause the object to move more slowly by acting in opposition to the speed of the incoming flow. Since drag is the part of the net aerodynamic force operating in the opposite direction to the direction of the movement, it differs from other resistance forces in that it directly depends on velocity.

Another way to describe it is to say that air resistance is caused by the leading surface of the object smacking with air molecules. Therefore, it can be claimed that the object's speed and cross-sectional area are the two most frequent variables that directly affect the quantity of air resistance. Thus, an increase in air resistance will be caused by both increasing speeds and cross-sectional areas.

In the context of aerodynamics and flight, the term "drag" refers to both the forces opposing and perpendicular to propulsion (i.e. lift).
