B. The new temperature =  20.833°C.

The resistance of a wire is:

R = ρL/A

where:

R is the resistance in ohms

ρ is the resistivity of the material in ohm-meters = 1.72 x 10-8 Ωm

L is the length of the wire in meters = 200 m

A is the cross-sectional area of the wire in square meters = πr² = π(0.25 mm)² = 4.909 x 10^-7 m²

Thus,

R = 1.72 x 10-8 Ωm x  200 m / 4.909 x 10^-7 m² = 7.58 Ω

B. The new temperature:

The temperature coefficient of resistance (α) is a measure of how much the resistance of a material changes with temperature.

The crew on the ship hears a frequency of about 1251.5 Hz when the aircraft is going away from them.

The crew hears a higher frequency  than the jet when the sound waves are condensed. The Doppler effect with a moving source can be calculated using the formula f' = (v v s) / (v v o) * f.  where:

The  frequency of the observer is indicated by f'.  

v o is the velocity of the crew relative to the medium (water), v s is the velocity of the source (jet) relative to the medium, and f is the emission frequency  (water).  

In this case, f = 1550 Hz (radiation rate), v s = 67.0 m/s (velocity of jet relative to water), v o = 0 m/s (velocity of crew at rest), and v = 343 m/s ( speed of sound).  By entering these numbers into the algorithm, we can determine the frequency  the crew will hear when the plane is close.

f' = 410 / 343 * 1550 Hz f' = (343 67) / (343 0) * 1550 Hz f' = (343 0) * 1550 Hz f' 1856.8 Hz

Hence the crew on board the ship hears a frequency of about 1856.8 Hz as the jet draws near.

We can get the frequency heard by the crew when the jet is traveling away by using the same parameters as previously but with v s = -67.0 m/s (negative sign indicates the aircraft is flying away).

F' = (276 / 343 * 1550 Hz) f' = (343 - 67) / (343 + 0) * 1550 Hz f' 1251.5 Hz

The crew on the ship, therefore, hears a frequency of about 1251.5 Hz when the aircraft is going away from them.

Hooke's law is a crucial concept in civil engineering as it relates to materials' behavior under mechanical stress. It establishes a linear relationship between the force applied to an elastic material and the resulting deformation or strain experienced by the material. The law states that deformation is directly proportional to the applied force, as long as the material remains within its elastic limits.

In civil engineering, Hooke's law is significant for several reasons:

Structural Analysis: Hooke's law helps engineers analyze structures and materials under various loads. By understanding how materials deform under stress, engineers can accurately predict structure responses, such as beams, columns, and bridges. This will ensure their safety and stability.

Material Selection: Hooke's law assists civil engineers in selecting appropriate materials for construction projects. It provides insights into materials' mechanical properties, such as elasticity, strength, and stiffness. These are essential considerations in designing structures that withstand anticipated loads.

Design of Elements: Hooke's law is utilized in the design of structural elements to ensure they can withstand expected forces and deformations. By considering materials' elastic behavior, engineers can calculate the required dimensions, reinforcement, and support systems to prevent excessive deformations or failures.

Structural Testing: Hooke's law guides materials and structural component testing and evaluation. Engineers can conduct experiments to measure elastic properties of materials, such as Young's modulus, Poisson's ratio, and shear modulus. This is done by applying known forces and measuring the resulting deformations. These tests validate design assumptions and ensure safety standards compliance.

Load Distribution: Hooke's law helps understand how loads are distributed within a structure. By considering materials' elasticity, engineers can determine how forces are transmitted through structural elements. This allows for an optimized design that efficiently distributes loads and minimizes stress concentrations.

Hooke's law provides a fundamental framework for analyzing materials and structures' behavior under mechanical stress. This enables civil engineers to design and construct safe, efficient, and reliable infrastructure.

An insulating vessel contains 80 g of a block of ice at -12 °C. If 450 g of water at 60 °C is added to the ice in the vessel, Energy required for complete melting = [tex]80 g X (3.33 X 10^3 J/kg)[/tex].

To determine whether the ice will soften absolutely and calculate the final temperature of the system, we need to do not forget the strength transferred among the ice and water at some stage in the procedure.

(i) To decide if the ice will melt completely, we need to examine the energy won by using the ice to the electricity required for complete melting.

Energy received by way of the ice = mass of ice × particular heat capacity of ice × alternate in temperature

Energy won by using the ice = eighty g × 2100 J/(kg·°C) × (final temperature - (-12°C))

Energy required for complete melting = mass of ice × latent warmth of fusion of ice

Energy required for whole melting = 80 g × (3.33 × 10^3 J/kg)

If the strength received via the ice is extra than or same to the electricity required for entire melting, the ice will soften completely.

(ii) To calculate the very last temperature of the gadget, we want to keep in mind the power transferred between the ice and water.

Energy won by the water = mass of water × unique heat ability of water × trade in temperature

Energy received by using the water = 450 g × 4200 J/(kg·°C) × (final temperature - 60°C)

Since electricity is conserved inside the machine, the power gained by means of the ice and water need to be identical:

Energy gained through the ice = Energy won by the water

Using the equations above, we will installation the following equation:

80 g × 2100 J/(kg·°C) × (very last temperature - (-12°C)) = 450 g × 4200 J/(kg·°C) × (very last temperature - 60°C)

The angular acceleration of the ball is approximately 800 rad/s².  the angular acceleration of the soccer ball is approximately -35.89 rad/s².

Question 1:

To find the angular acceleration of the ball rolling down the incline, we can use the following formula:

v = ω * r

where:

v is the linear velocity (2.0 m/s),

ω is the angular velocity, and

r is the radius of the ball (0.05 m).

We can also use the formula to relate linear and angular acceleration:

a = α * r

where:

a is the linear acceleration,

α is the angular acceleration, and

r is the radius of the ball (0.05 m).

Given that the ball rolls down the incline from rest, the initial angular velocity (ω0) is zero.

Using the equations above, we have:

2.0 m/s = ω * 0.05 m

ω = 2.0 m/s / 0.05 m

ω = 40 rad/s

Since the initial angular velocity is zero, the change in angular velocity (Δω) is equal to the final angular velocity (ω).

Using the equation a = α * r, we can rewrite it as α = a / r:

α = ω / r

α = 40 rad/s / 0.05 m

α ≈ 800 rad/s²

Question 2:

To calculate the time the soccer ball was rolling, we can use the formula:

t = d / v

where:

t is the time,

d is the distance traveled (25.0 m), and

v is the linear velocity (circumference of the ball times the angular velocity).

The circumference of the ball (C) can be calculated using the formula:

C = π * d

where:

d is the diameter of the ball (0.20 m).

Given that the ball has a diameter of 20 cm, the circumference is:

C = π * 0.20 m

C ≈ 0.628 m

Using the formula v = C * ω, we have:

v = 0.628 m * 15 rev/s

v ≈ 9.42 m/s

Substituting the values into the equation t = d / v, we find:

t = 25.0 m / 9.42 m/s

t ≈ 2.66 s

Therefore, the soccer ball was rolling for approximately 2.66 seconds.

To find the angular acceleration, we can use the formula:

α = Δω / t

Given that the initial angular velocity (ω0) is 15 rev/s and the final angular velocity (ω) is zero, the change in angular velocity (Δω) is:

Δω = ω - ω0

Δω = 0 - 15 rev/s

Δω = -15 rev/s

Converting the change in angular velocity to radians per second (rad/s):

Δω = -15 rev/s * (2π rad/rev)

Δω = -30π rad/s

Substituting the values into the formula α = Δω / t, we find:

α = (-30π rad/s) / 2.66 s

α ≈ -35.89 rad/s²

Note that the negative sign indicates a deceleration or slowing down of the rotation.

The magnitude of the equilibrant force is equal in magnitude but opposite in direction to the resultant vector R. Therefore, the magnitude of the equilibrant force is 500 dyne.

The correct answer is option D.

To find the magnitude of the equilibrant force, we need to determine the resultant of the two given forces and then find its opposite vector, which will be the equilibrant force.

Let's break down each force into its x-component and y-component:

For F1 = 300 dyne at an angle of 309° with the +x-axis:

F1x = F1 * cos(309°)

= 300 dyne * cos(309°)

= -259.8 dyne (negative because it is in the opposite direction of the positive x-axis)

F1y = F1 * sin(309°)

= 300 dyne * sin(309°)

= -150 dyne (negative because it is in the opposite direction of the positive y-axis)

For F2 = 400 dyne at an angle of 120° with the +x-axis:

F2x = F2 * cos(120°)

= 400 dyne * cos(120°)

= -200 dyne (negative because it is in the opposite direction of the positive x-axis)

F2y = F2 * sin(120°)

= 400 dyne * sin(120°)

= 346.4 dyne

Now, we can add the x-components and y-components separately:

Rx = F1x + F2x

= -259.8 dyne + (-200 dyne)

= -459.8 dyne

Ry = F1y + F2y

= -150 dyne + 346.4 dyne

= 196.4 dyne

The resultant vector R is given by:

R =[tex]\sqrt{(Rx^2 + Ry^2)}[/tex]

The component of soil that has very small grains and is sticky when wet is option A. clay.

Clay particles are the smallest among the soil particles, with a size of less than 0.002 millimeters. Due to their small size, clay particles have a large surface area relative to their volume, which contributes to their unique properties. When clay soil comes into contact with water, the water molecules adhere to the surface of the clay particles, forming a thin film around them.

This results in the stickiness and plasticity of clay when wet. The adhesive properties of water to the clay surface are due to the presence of charged particles on the surface of the clay particles, known as cation exchange capacity. This allows the clay particles to attract and hold onto water molecules, creating a cohesive and sticky texture.

In addition to its stickiness, clay also has a high capacity for retaining water. The small spaces between clay particles, called micropores, can hold water tightly, making it less prone to drainage.

Ice and snow in the polar regions play a crucial role in shaping the climate of these areas through various mechanisms.

Firstly, ice and snow have high albedo, meaning they reflect a significant portion of the incoming solar radiation back into space. This reflective property reduces the amount of solar energy absorbed by the Earth's surface, leading to cooler temperatures in the polar regions.

This phenomenon helps maintain the polar climate and contributes to the formation of ice caps and glaciers.

Secondly, the presence of ice and snow influences the movement of ocean currents and atmospheric circulation patterns. Melting ice and snow contribute to the formation of cold, dense water in polar regions, which sinks and initiates deep ocean currents.

These currents, such as the thermohaline circulation, play a vital role in redistributing heat globally and regulating climate patterns.

Furthermore, the vast ice sheets in polar regions act as a thermal insulator, preventing the transfer of heat between the atmosphere and the underlying ocean. This insulation effect helps maintain lower temperatures in the polar regions, influencing the overall climate and weather patterns.

Additionally, the freezing and melting of ice impact the salinity of the surrounding seawater. Changes in salinity affect the density of water, which can further influence ocean circulation and climate patterns.

In summary, the presence of ice and snow in the polar regions contributes to the climate by reflecting solar radiation, influencing ocean currents and atmospheric circulation, and acting as a thermal insulator. These factors play a significant role in shaping the unique climate conditions found in the polar regions.

The temperature range, from the highest to the lowest, is generally greater for land compared to the oceans. This occurs due to several factors.

Firstly, land has lower heat capacity than water. Heat capacity refers to the amount of heat energy required to raise the temperature of a substance.

Since land has a lower heat capacity, it heats up and cools down more quickly compared to water. As a result, land temperatures can experience more significant fluctuations throughout the day and across seasons.

Secondly, land surfaces are exposed to direct solar radiation, whereas the oceans have a moderating effect due to their vastness and water's ability to distribute and store heat. The high specific heat of water enables it to absorb and release heat more slowly, resulting in a more stable temperature range.

Additionally, land surfaces are influenced by various geographical features such as mountains, valleys, and different types of land cover (forests, deserts, etc.). These features can create local temperature variations, further contributing to a wider temperature range on land.

In summary, the temperature range is typically greater for land compared to the oceans due to the lower heat capacity of land, the direct exposure to solar radiation, and the influence of geographical features.
