Gas molecules which has greater average molecular speed at 25° is    a)CH₄. So,correct option is a  

As per Active Atomic Hypothesis of Gases, it makes sense of that gas particles are in constant movement and display preferably flexible impacts. Gas particles are found in a steady condition of irregular movement and particles generally travel in an orderly fashion until and except if they crash into another molecule. It likewise makes sense of that the typical motor energy of a gathering of gas particles is straightforwardly relative to temperature. In an ideal gas condition, the speed related with a gathering of particles can be found.

We know that average molecular speed is inversely proportional to the molecular mass of the gas. In other words

average molecular speed α 1 / Molecular mass

So,

Molecular mass of CH₄=12+4ˣ1=16g

Molecular mass of Kr=84g

Molecular mass of N₂=14ˣ2=28g

Molecular mass of CO₂=12+16ˣ2=44g

The only option where the total work done is positive is:

c) vi = 5m/s, vf = 2m/s.

The work done on a particle is given by the equation W = F * d * cos(θ), where F is the force acting on the particle, d is the displacement of the particle, and θ is the angle between the direction of the force and the direction of displacement.

In this case, the force is a constant force, such as gravity or a spring force, and the displacement is along the x-axis, so θ = 0. The work done is then given by W = F * Δx, where Δx is the change in x, or W = F * (xf - xi).

If the force is acting in the same direction as the displacement, the work done is positive. If the force is acting in the opposite direction as the displacement, the work done is negative.

As Newton's law itself is a law of motion which forms the basis of dynamics by formulating a force against the effect of motion on a particular object. This formula became known as Newton's 1st, 2nd and 3rd law. Because of his services which were considered very noble, Newton was honored with the title of Sir Isaac Newton.

According to the Big Bang Theory, the universe began expanding about 13.7 billion years ago from a single, hot and dense point (aka, a singularity) in an event known as the Big Bang.

This event marked the beginning of space and time, and set in motion the expansion of the universe that continues today. Since then, the universe has been growing in size and complexity, and is now estimated to be over 13.8 billion years old.

The Big Bang Theory states that the universe was initially a very hot and dense state and has been continuously expanding and cooling ever since. This expansion is thought to be driven by the force of gravity, which pulls matter and energy together. As the universe expands, the matter and energy become more spread out, causing the temperature to drop. This cooling process has allowed for the formation of stars and galaxies, as well as the emergence of complex structures like planets, moons, and life.

The magnitude of the electric force, F, on the test charge is given by:

F = k * q0 * (p / (r^2))

The magnitude of the electric force on a test charge q0 placed at a distance r away from a dipole can be calculated using Coulomb's law. Coulomb's law states that the force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.

For a dipole, the electric force can be calculated by considering the force between the test charge and each of the charges in the dipole and then adding the forces vectorially.

A dipole is a two-point electrical charge system, where one point has a positive charge and the other has an equal and opposite negative charge.

Dipoles are fundamental to many electrical and chemical processes, and they play a crucial role in molecular bonding and interactions. Dipoles can also be created artificially, such as in an electric dipole or a magnetic dipole.

The magnitude of the electric force, F, on the test charge is given by:

F = k * q0 * (p / (r^2))

where k is Coulomb's constant (approximately 8.99 x 10^9 N(m/C)^2), p is the dipole moment, and r is the distance between the test charge and the dipole. The dipole moment can be calculated from the magnitude of the charges in the dipole and the separation distance between them.

We can solve for the velocity of the block at 4.80 m from the top of the incline using the kinematic equation for constant acceleration:

v = v₀ + at

where v0 represents the initial velocity (0 m/s), a represents the acceleration, t represents the time elapsed, and v represents the final velocity.

We can also use the equation: because the block is sliding down the incline with constant acceleration.

d = v₀t + (1/2)at²

d denotes the distance traveled.

To calculate the acceleration, we can plug in the final velocity and distance from the top of the incline into this equation:

7.80 m = (1/2)at²

7.80 m = (1/2)(a)(t₁)²

Where t1 is the time elapsed between the top and bottom of the incline.

Calculating the acceleration:

a = (2)(7.80 m) / t₁²

We can now use this acceleration and the time elapsed to solve for the velocity of the block 4.80 m from the top of the incline:

v = v₀ + at

v = 0 m/s + a(t₂)

Where t₂ is the time elapsed from the top of the incline to 4.80 m down.

We can use the equation:

d = v₀t + (1/2)at²

to solve for t₂:

4.80 m = 0 m/s(t₂) + (1/2)a(t₂)²

Solving for t₂:

t₂ = √(2d / a)

Substituting t₂ and an into the equation for v:

v = 0 m/s + a(t₂)

v = a √(2d / a)

And we have the velocity of the block 4.80 m from the top of the incline.

The reservoir that has the largest deposit of carbon is ocean (C)

The oceans and other bodies of water contain 36,000 gigatons of carbon in the form of sediments and rocks buried deep below the surface. The carbon content of the Earth's crust is estimated to be 550 gigatons. This is the biosphere, which includes the soil as one component. Accordingly, all of this information leads us to the conclusion that the ocean is the largest carbon reservoir.

Through the carbon cycle, which consists of both slow and quick processes, carbon moves from one reservoir to the next. In the slow carbon cycle, the movement of carbon takes place via a chain of chemical processes and tectonic activity. On the other hand, in the fast carbon cycle, life on Earth is responsible for the movement of carbon. The average annual carbon flux in the fast cycle is approximately one thousand times higher than that in the slow phase.

The thermal energy content of the object should decrease over time as heat is transferred from the object to the environment.

Thermal energy is the energy that is generated from the movement of molecules in a material. It is a form of kinetic energy, or energy that is being moved. Thermal energy is generated from the heat of the sun and is the main form of energy that powers the Earth’s climate system.

As heat flows from the object to the surrounding environment, the object will cool down until it reaches the same temperature as the environment. This is because the thermal energy content of the object is determined by the temperature of the object and the temperature of the environment is lower than the temperature of the object.

To stay at a hotter temperature than the surroundings, the object must constantly absorb more heat than it releases. This can be done through processes such as conduction and convection, where the object will absorb heat from its surroundings. Additionally, the object can also absorb heat from the sun or other sources of heat. As long as the object is absorbing more heat than it is releasing, it will remain at a higher temperature than the environment.
