An object in motion, such as a car or a bird, has kinetic energy but not potential energy.

An object in motion has kinetic energy, but it doesn't necessarily have potential energy. Potential energy is the energy that an object possesses due to its position in a gravitational field or an electric field. An object that has the potential to move, but isn't moving, has potential energy. However, if an object is already in motion, it doesn't have the potential to move, and hence it doesn't have potential energy. This is because potential energy is directly proportional to an object's position or height above a surface with a gravitational or electric field.For instance, when a car is traveling down a road, it has kinetic energy, which is proportional to its mass and velocity, but it doesn't have potential energy because it's not at any height or position above the ground that can produce potential energy. Similarly, a bird that's flying through the air has kinetic energy because it's in motion, but it doesn't have potential energy because it's not above the ground or any surface with a gravitational or electric field.

To solve this problem, we'll use Charles's Law, which states that the volume of a gas is directly proportional to its temperature when the pressure and the amount of gas are kept constant. Mathematically, the law can be expressed as V1/T1 = V2/T2, where V1 and V2 are the initial and final volumes, and T1 and T2 are the initial and final temperatures.

In this case, we're given:
V1 = 100 mL (initial volume)
T1 = 200 K (initial temperature)
T2 = 300 K (final temperature)
We need to find V2 (final volume).

Applying Charles's Law, we get:
(100 mL) / (200 K) = V2 / (300 K)

Now, we can solve for V2:
V2 = (100 mL) * (300 K) / (200 K)
V2 = 30000 mL / 200 K
V2 = 150 mL

So, the new volume of the gas at 300 K is 150 mL. In summary, when the temperature of the gas increased from 200 K to 300 K, its volume increased from 100 mL to 150 mL due to the direct proportionality between the volume and temperature of a gas as stated by Charles's Law.

What is the Trade Mart in Dallas, and why is it significant in relation to the assassination of President John F. Kennedy?

The Trade Mart was a large exhibition hall located in Dallas, Texas, USA. It was originally built in 1936 as part of the Texas Centennial Exposition and was designed to showcase Texas industry and agriculture. Over the years, the Trade Mart became a popular venue for trade shows, conventions, and other events.

One of the most significant events to take place at the Trade Mart was the International Trade Mart luncheon on November 22, 1963. This event was attended by President John F. Kennedy, who was assassinated later that day while riding in a motorcade through Dealey Plaza in Dallas.

After the assassination, the Trade Mart became a site of controversy and speculation. Some conspiracy theorists suggested that the Trade Mart was part of a larger conspiracy to assassinate Kennedy, while others believed that evidence related to the assassination was hidden there. However, there is no evidence to support these claims.

Magellan could not use Polaris for navigation in the Southern Hemisphere because it is not visible from that region.

Polaris, also known as the North Star, has been used for navigation by explorers in the Northern Hemisphere. However, when Magellan sailed to the Southern Hemisphere, he could not use Polaris for navigation.

Polaris is located very close to the North Celestial Pole, which means it appears to be almost directly above the Earth's North Pole. As a result, when navigating in the Northern Hemisphere, Polaris remains relatively fixed in the night sky, providing a reliable point of reference for determining north.

In the Southern Hemisphere, however, Polaris is not visible. This is because it is located close to the Earth's North Pole, and the South Celestial Pole does not have a bright star comparable to Polaris. Navigators in the Southern Hemisphere must rely on other celestial objects, such as the Southern Cross or specific constellations, to determine their direction.

Therefore, Magellan could not use Polaris for navigation in the Southern Hemisphere because it is not visible from that region.

Answer:

Friction is defined as the force that opposes the motion of a solid object over another. There are mainly four types of friction: static friction, sliding friction, rolling friction, and fluid friction. Friction and normal force are directly proportional to the contacting surfaces and it doesn’t depend on the hardness of the contacting surface. With the increase in relative speeds, the sliding friction reduces whereas fluid friction increases with the increase in the relative speed, also fluid friction is dependent on the viscosity of the fluid.

In sliding motion, each point on the body has only translational or linear motion. But in case of rolling motion, different points have a combination of linear as well as rotational motion.

The flux per unit area of the toxic gas towards the residential room is 0.351 mg/(m^2 * minute).

To calculate the flux per unit area of the toxic gas towards the residential room, we can use Fick's law of diffusion, which states that the flux (J) is proportional to the concentration gradient (ΔC) and the diffusion coefficient (D), and inversely proportional to the distance (Δx):

J = -D * (ΔC / Δx)

In this case, we want to calculate the flux per unit area, so we need to divide the flux by the area of the tunnel.

Length of the tunnel (Δx) = 5 m

Diameter of the tunnel = 1.5 m (radius = 0.75 m)

Concentration in the chamber (C1) = 30 mg/m^3

Concentration in the residential room (C2) = 3 mg/m^3

Diffusion coefficient (D) = 0.065 m^2/minute

First, let's calculate the concentration gradient:

ΔC = C2 - C1 = 3 mg/m^3 - 30 mg/m^3 = -27 mg/m^3

Next, let's calculate the area of the tunnel:

Area = π * (radius)^2 = π * (0.75 m)^2 = 1.767 m^2

Now, we can calculate the flux per unit area:

J = -D * (ΔC / Δx) = -0.065 m^2/minute * (-27 mg/m^3 / 5 m) = 0.351 mg/(m^2 * minute)

Answer:

The coefficient of friction is (F/(19.6·m)

Explanation:

The given parameters are;

The force applied to the immovable body = F

The time duration the force acts = t

The time the body spends in motion = 3·t

The acceleration due to gravity, g = 9.8 m/s²

From Newton's second law of motion, we have;

The impulse of the force = F × t = m × Δv₁

Where;

Δv₁ = v₁ - 0 = v₁

The impulse applied by the force of friction, \(F_f\) is \(F_f\) × (3·t - t) =  \(F_f\) × (2·t)

Given that the motion of the object is stopped by the frictional force, we have;

The impulse due to the frictional force = Momentum change = m × Δv₂ = \(F_f\) × (2·t)

Where;

Δv₂ = v₂ - 0 = v₂

Given that the velocity, v₂, at the start of the deceleration = The velocity at the point the force ceased to  act, v₁, we have;

m × Δv₂ = \(F_f\) × (2·t) = m × Δv₁ = F × t

∴ \(F_f\) × (2·t) = F × t

\(F_f\) = F × t/(2·t) = F/2

The coefficient of dynamic friction, \(\mu _k\) = Frictional force/(The weight of the body) = (F/2)/(9.8 × m)

\(\mu _k\) = (F/(19.6·m)

The coefficient of friction, \(\mu _k\) = (F/(19.6·m)

The mass of air in the room is 604.8 kg

The volume of air in the room is:

Volume = length × width × height

= 10 m × 12 m × 4 m

= 480 cubic meters

The mass of air in the room can be calculated using the density of air:

Mass = Density × Volume

= 1.26\(kg/m^3\) × 480 \(m^3\)

= 604.8 kg

Therefore, the mass of air in the room is 604.8 kg

The mass of air in a given space can be calculated by multiplying the density of the air by the volume of the space. The density of air at a given temperature and pressure can be found in reference tables or online sources.

No work is being done on a block travelling vertically if an 84 N force has been applied to the right side of the block horizontally. Work is described as the result of applied force and object movement in the force's direction.

There is no change in the force's direction in this situation since the block is travelling vertically and the force is exerting itself horizontally. Therefore, there has been no work done on the block.

This situation might appear strange, but it serves to illustrate the notion that labour can only be accomplished when the applied force and displacement are in harmony.
