Plates moving at 7.3 cm/year are approximately 5.615 times faster than those moving at 1.3 cm/year.

The speed at which plates move is determined by the relative motion between tectonic plates along their boundaries. To compare the speeds of plates moving at different rates, we can calculate the ratio between their velocities.Let's consider plates moving at 7.3 cm/year and 1.3 cm/year. To find the factor by which the faster plates are moving compared to the slower plates, we divide their velocities:

7.3 cm/year / 1.3 cm/year = 5.615

In other words, for every unit of time, the faster plates cover approximately 5.615 times the distance covered by the slower plates. This difference in speed can have significant implications for geological processes such as the accumulation of strain along plate boundaries, the occurrence of earthquakes, and the formation of mountain ranges. It highlights the dynamic nature of tectonic plate movements and their influence on Earth's geology and surface features.

Answer:

I think 75 m

Explanation:

tell if it was correct

If the moment of interia is 6.0 kg-m2 . 1.50 N-m the torque applied for the first two seconds.

As per the question statement, the moment of inertia is 6.0 kg-m².

Hence, to determine the torque applied for the first two seconds, we must know the angular acceleration.

Therefore, the angular acceleration is given by:

α=τ/I

Where α is the angular acceleration, τ is the torque, and I is the moment of inertia.

Substituting the given values, we get:

α=τ/I

⇒αI=τ

⇒τ=αI

The moment of inertia I is given to be 6.0 kg-m².

Further, the torque can be determined by calculating the angular acceleration α.

However, the angular acceleration is not provided in the question statement. Hence, we need to make some assumptions to determine α.

Let us assume that the angular acceleration is uniform i.e., constant.

Also, we assume that the initial angular velocity is zero.

Using these assumptions, we can calculate the angular acceleration as:

α=2θ/\(t^2\)

Where θ is the angular displacement and t is the time interval.

Since the question statement does not provide the value of θ,

let us assume that the object has rotated by 90 degrees in the first 2 seconds.

Therefore, θ = 90° = π/2 radian.

Substituting the given values, we get:

α=2θ/\(t^2\)

α=2π/\(2^2\) =π/4\,rad/\(s^2\)

Therefore, the angular acceleration α is π/4 rad/s².

Substituting this value along with the given moment of inertia I, we get:

τ=αI

τ=(π/4) x 6.0

τ=1.50\,N-m

Therefore, the torque applied for the first two seconds is 1.50 N-m, rounded off to two decimal places.

When an object is subjected to two opposing forces, we need to calculate the net force acting on the object. In this scenario, the object is pulled northward with a force of 10 N and southward with a force of 15 N.

The magnitude of the net force is determined by subtracting the smaller force from the larger one. In this case, the net force can be calculated as 15 N - 10 N = 5 N. So, the magnitude of the net force is 5 N.

The direction of the net force is determined by the direction of the larger force. In this case, the larger force is acting southward, so the direction of the net force is southward.

Therefore, the magnitude and direction of the net force acting on the object are 5 N southward. It is important to note that the magnitude of the net force is smaller than the individual forces acting on the object, which means that the object will not move in the direction of either of the forces acting on it.

In case the forces acting on the object were equal, the net force would be zero, and the object would not move. If the forces acting on the object were unbalanced, the net force would be the difference between the two forces, and the object would move in the direction of the net force.

No, the sun cannot explain global warming. Global warming is a phenomenon in which the temperature of the Earth's surface and atmosphere is rising continuously due to human activities such as deforestation, burning of fossil fuels, and industrialization.

This increase in temperature cannot be explained only by an increase in solar radiation.There are several factors which contribute to global warming, including greenhouse gases such as carbon dioxide, methane, and water vapor. These gases trap heat in the Earth's atmosphere, which causes the planet's temperature to rise. The sun's radiation does contribute to global warming, but it is not the main cause.

i) To calculate the increase in solar radiation that would cause the Earth to warm up by 1 K, we can use the following formula:ΔS = ΔT / αWhere ΔS is the increase in solar constant, ΔT is the increase in temperature, and α is the Earth's albedo (reflectivity).α = 0.30 is the standard value used for the Earth's albedo.ΔS = ΔT / αΔS = 1 K / 0.30ΔS = 3.33 W/m2So, to explain the increase in temperature of 1 K over the last hundred years, the solar constant would need to increase by 3.33 W/m2.

ii) The observed fluctuation of the solar constant over the past 400 years has been around 0.1% to 0.2%. This is much smaller than the 3.33 W/m2 required to explain the increase in temperature of 1 K over the last hundred years. Therefore, it is unlikely that the sun is the main cause of global warming.

The sun cannot explain global warming. While the sun's radiation does contribute to global warming, it is not the main cause. The main cause of global warming is human activities, particularly the burning of fossil fuels, which release large amounts of greenhouse gases into the atmosphere.

The true azimuth of the AB alignment is 91º 52' (east of north), the magnetic azimuth is 100º 22' (east of north), and the grid azimuth is 108º 52' (east of north).

To find the true azimuth, magnetic azimuth, and grid azimuth of the AB alignment, we need to consider the magnetic declination. The magnetic declination indicates the angle between true north and magnetic north at a specific location. In this case, the magnetic declination is 8º 30' E, which means that the magnetic north is 8º 30' east of the true north.

To calculate the true azimuth, we subtract the magnetic declination from the grid azimuth. The grid azimuth is given as 100º 22', so subtracting the magnetic declination of 8º 30' E gives us a true azimuth of 91º 52' (east of north).

The magnetic azimuth remains the same as the grid azimuth, which is 100º 22' (east of north).

The grid azimuth is calculated by adding the magnetic declination to the true azimuth. Since the magnetic declination is east, we add it to the true azimuth. Adding 8º 30' E to the true azimuth of 91º 52' gives us a grid azimuth of 108º 52' (east of north).

3. Specific Heat Capacity = 15686 J / (1.1 kg x (47°C - 16°C)) = 1479.2 J/kg°C.

4. Heat = 0.778 kg x 4186 J/kg°C x (94°C - 26°C) = 200508 J.

5. Sample 3 has the highest specific heat capacity because it has the    greatest temperature change for the same amount of heat applied.

Energy is the ability to do work, or the capacity to produce an effect. It can be classified into two main forms — kinetic energy, which is the energy of motion, and potential energy, which is stored energy due to an object's position or state.

1: The amount of heat needed to raise the temperature of a 3 kg sample of aluminium from 40°C to 95°C is 27000 J.

This can be calculated by using the formula: Heat = Mass x Specific Heat Capacity x Change in Temperature.

Therefore, Heat = 3 kg x 900 J/kg°C x (95°C - 40°C) = 27000 J.

2: The temperature change of a 4.1 kg sample of copper when 780 J of energy is applied is 2.02°C.

This can be calculated by using the formula: Change in Temperature = Heat / (Mass x Specific Heat Capacity).

Therefore, Change in Temperature = 780 J / (4.1 kg x 385 J/kg°C) = 2.02°C.

3: The specific heat capacity of iron is 1479.2 J/kg°C.

This can be calculated by using the formula: Specific Heat Capacity = Heat / (Mass x Change in Temperature).

Therefore, Specific Heat Capacity = 15686 J / (1.1 kg x (47°C - 16°C)) = 1479.2 J/kg°C.

4: The amount of heat removed to lower the temperature of a 0.778 kg sample of water from 94°C to 26°C is 200508 J.

This can be calculated by using the formula: Heat = Mass x Specific Heat Capacity x Change in Temperature.

Therefore, Heat = 0.778 kg x 4186 J/kg°C x (94°C - 26°C) = 200508 J.

5: Sample 3 has the highest specific heat capacity because it has the greatest temperature change for the same amount of heat applied. This means that Sample 3 requires more energy to increase its temperature than Samples 1 and 2, thus indicating that it has the highest specific heat capacity.

The theory that suggests the Milky Way formed from a large proto-galactic gas cloud is known as the Hierarchical Model or Monolithic Collapse Model of galaxy formation.

According to this theory, the Milky Way and other galaxies formed through the gradual accumulation and collapse of gas clouds in the early universe. It proposes that initially, smaller structures like dwarf galaxies or gas clouds existed. Over time, these smaller structures merged through gravitational interactions, eventually forming larger structures like the Milky Way. In the hierarchical model, the formation of galaxies is a bottom-up process, where small structures merge and accrete matter to form larger and more massive systems. It explains the diverse population and distribution of stars, the presence of globular clusters, and the overall structure of galaxies like the Milky Way.
