the fast carbon cycle follows the movement of carbon through living (biotic) components of an ecosystem. This occurs faster because life moves more quickly. The fast carbon cycle focuses primarily on the biosphere, while the slow carbon cycle is more involved with the hydrosphere, lithosphere and atmosphere.

Explanation:

In the context of motion tracking or sensor systems, radial deviation refers to the movement of an object or target along a radial axis from a central point. On the other hand, rotation refers to the angular movement or change in orientation of an object.

When it comes to sensitivity, the radial deviation is most sensitive to the target position, meaning that even slight changes in the position of the target relative to the central point can be detected accurately. This sensitivity allows for precise measurement and tracking of the object's location along the radial axis.

On the other hand, rotation is the most sensitive to object orientation. Small changes in the orientation or angle of the object can have a significant impact on the measured rotation. This sensitivity is crucial in applications where detecting and tracking the orientation of objects is essential, such as virtual reality systems or robotics.

Understanding the sensitivity of radial deviation and rotation helps in designing and calibrating motion-tracking systems to ensure accurate and reliable measurements. By considering these factors, developers can optimize the system's performance for specific applications that require precise position or orientation tracking.

Explanation:

To prevent the motor speed from increasing until it fails mechanically, a load should always be connected to the motor.

A motor is designed to operate under a specific load. Without a load connected to the motor, it can spin freely and reach dangerously high speeds. This can lead to mechanical failures such as bearing damage or rotor imbalance, which can ultimately cause the motor to fail. By connecting a load to the motor, it creates a resistance that limits the speed and keeps it within a safe operating range.

The load acts as a counterforce to the motor's rotational motion, balancing the power output. It provides the necessary friction and resistance to control the motor speed. Without a load, the motor can experience a phenomenon called "overspeeding," where it exceeds its designed RPM (rotations per minute). This can result in excessive wear and tear, heat buildup, and potential damage to the motor components.

By always connecting a load to the motor, it ensures that the motor operates within its intended parameters and prevents it from reaching speeds that could lead to mechanical failure. The appropriate load for a motor depends on its design and application, and it should be chosen carefully to match the motor's specifications and requirements.

The free metal electrons in a wire collide with the particles transporting the charge through the wire.

Strong metallic connections keep the constituent parts of a metal together. The particles are arranged in a predictable pattern and are close together. The outside electrons of metal atoms are loose, creating a "sea" of delocalized or free negative charge around the densely packed positive ions.

Hence, the flow of charged particles or charge carriers is what constitutes electric current. Any charged particle, such as an electron, proton, or ion, can serve as the charge carrier. In an electric circuit, electrons typically carry the charge.

Explanation:

Answer: n = 0 N at the highest point

Explanation:

The critical speed for a roller coaster car doing a loop-the-loop is determined by the condition that the normal force at the highest point is equal to zero.

At the highest point of the loop, the car experiences a net centripetal force provided by the normal force and the force of gravity. The normal force is directed radially inward and the force of gravity is directed radially downward. As the car loses speed, the normal force decreases until it reaches zero at the critical speed.

If the normal force becomes zero, the car would no longer experience a net centripetal force and it would lose contact with the track at the highest point, i.e., the car would come off the track.

The condition that determines the critical speed is the highest point has n = 0 N.

Answer:

(a) The weight of the wood is approximately 5,886 N

(b) The weight of the stone is approximately 1,962 N

Explanation:

The given parameters are;

The base area of the wood, A = 1 m × 1 m = 1 m²

The depth to which the wood is submerged below the water, d = 0.6 m

The depth further the wood sinks when a stone is placed on the wood, Δd = 0.2 m

The density of water, ρ = 1,000 kg/m³

(a) Archimedes' principle states that the up-thrust, or upward force acting on an object submerged in a fluid, is equal to the weight of the displaced fluid.

For a floating object such as the wood, the up-thrust is equal to the weight of the object

The weight of the water displaced, W = The volume of the displaced water, V × The density of the water, ρ × The acceleration due to gravity, g

W = V × ρ × g

'V' is the same as the volume of the submerged wood, therefore;

V = A × d = 1 m × 1 m × 0.6 m = 0.6 m³

g ≈ 9.81 m/s²

Therefore;

W = 0.6 m³ × 1,000 kg/m³ × 9.81 m/s² ≈ 5,886 Newtons

The weight of the water displaced, W ≈ 5,886 N = The up-thrust = The weight of the wood

∴ The weight of the wood, W ≈ 5,886 N

(b) Similarly, the weight of the stone, \(W_{stone}\) is equal to the weight of the additional volume of water displaced

∴ \(W_{stone}\) = A × Δd × ρ × g

By plugging in the values, we get

\(W_{stone}\) ≈ 1 m² × 0.2 m × 1,000 kg/m³ × 9.81 m/s² = 1,962 N

The weight of the stone, \(W_{stone}\) ≈ 1,962 Newtons

Answer:

Ted is correct

Explanation:

The equation for gravitational potential energy is PE = m·g·h

The equation for gravitational kinetic energy is KE = 1/2·m·v²

Where:

m = Mass of the object (The racing car)

g = Acceleration due to gravity

h = The height to which the object is raised

v = Velocity of motion of the object

From the principle of conservation of energy, energy can neither be created nor destroyed but changes from one form to another, we have;

Potential energy gained from location at height h = Kinetic energy gained as the object moves down the level ground

m·g·h = 1/2·m·v² canceling like terms gives

g·h = 1/2·v²

v = (√2·g·h)

If the speed is doubled, we have

2·v = 2× (√2·g·h) =  (√2·g·4·h)

Therefore, if 2·v = v₂ then v₂ =  (√2·g·4·h)

Since g, the acceleration due to gravity, is constant, it means that the initial  height must be multiplied or increased 4 times to get the new height, that is we have;

v₂ =  (√2·g·4·h) = (√2·g·h₂)

Where:

4·h = h₂

Which gives;

v₂² = 2·g·h₂

1/2·v₂² = g·h₂

1/2·m·v₂² = m·g·h₂ Just like in the first relation

Therefore, Ted is correct s they need to go up four times the initial height to double the speed.

Explanation:

The net force acting on the bicyclist is 11.022 Newton.

Given the following data:

To find the net force acting on the bicyclist, we would apply Newton's Second Law of Motion:

Mathematically, Newton's Second Law of Motion is given by this formula;

\(Force = mass\) × \(acceleration\)

First of all, we would determine the acceleration by using the third equation of motion;

\(V^2 = U^2 + 2aS\\\\1.5^2 = 0.5^2 + 2a(6)\\\\2.25 = 0.25 + 12a\\\\12a = 2.25 - 0.25\\\\12a = 2\\\\a = \frac{2}{12}\)

Acceleration, a = 0.167 \(m/s^2\)

Now, we can find the net force acting on the bicyclist:

\(Force = 66\) × \(0.167\)

Force = 11.022 Newton

Therefore, the net force acting on the bicyclist is 11.022 Newton.

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.
