Yes, we can compute by using stokes' theorem always.

By merely knowing information on the values of F along the border of S, Stokes' theorem states that we can compute the flux of curl F across surface S. On the other hand, by converting to a double integral of the curl of F over S, we may get the line integral of vector field F along the edge of surface S.

Let S be an N-unit normalized smooth surface that is orientated. Additionally, let's assume that S has a simple closed curve C as its border. If the surface is constantly on your left while you walk in the positive direction around C while directing your head in the direction of N, then the orientation of S induces the positive orientation of C. In light of this concept, we can say Stokes' theorem as,

The rubber is stretched and firmly gripped by the nail due to the pressure inside the tire, which prevents air leakage.

The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental measurable quantities of this phase of matter, pressure is a property shared by all gases. The amount of force applied to a given area is referred to as pressure.

Water flows at a rate of 3.11 kilograms / seconds through a hose with a diameter of 3 centimetres. then the speed of the water in the hose would be 4.40 meters / second.

The total displacement covered by any object per unit of time is known as velocity. The velocity of an object depends on the magnitude as well as the direction of the object.

As given in the problem if Water flows at a rate of 3.11 kg/s through a hose with a diameter of 3 cm.

Area of the hose = πD²/4

                            =3.14*3*3/40000

                            =7.065×10⁻⁴ meter²

The discharge of the water = 3.11/1000

                                              =3.11×10⁻³ meter³

The discharge of the water = area of hose ×velocity

3.11×10⁻³ meter³ = 7.065×10⁻⁴ meter²×velocity

velocity = 3.11×10⁻³ /  7.065×10⁻⁴

Potential energy of a body that is due to its position. To be more precise, the potential energy of a body of mass 'm' at height 'h' will be -

P[E] = mgh

Kinetic Energy of a body is the energy due to virtue of its motion. Mathematically -

K[E] = 1/2 mv²

Given is a image of a roller coaster ride and a table describing the energy magnitude theoretically.

As mentioned, Potential energy of a body that is due to its position and is given by - P[E] = mgh. Let's complete the energy table given -

1 → Location with least potential energy

From the formula -

P[E] = mgh

mg = constant

P[E] [tex]\alpha[/tex] h

Now, the point 2 represents the minimum height, therefore Point 2 is the location with least potential energy.

2 → Location with most potential energy

We know -

P[E] [tex]\alpha[/tex] h

The point with maximum height is 1, therefore it will represented by Point 1.

3 → Conversion of potential to kinetic energy

Assume that the velocity of the roller coaster is v. Now at point 1, the velocity will be zero. Therefore, the total energy of the roller coaster will be purely potential energy. When it starts to move from point 1 to point 4, its height will decrease and its velocity will increase. Therefore - at this stage (point 4), the potential energy will start to convert into kinetic energy.

4 → Conversion of kinetic to potential energy

Use the same concept discussed in part - 3. In this case it is moving from lower point to higher point. So, height will increase and velocity will decrease. Therefore, the point 3 represents the stage at which kinetic energy will start to convert into potential energy.

Therefore, the complete table representing the energy description at different stages is

The displacement covered by a body per unit time is defined as its velocity. Velocity is a vector quantity that indicates the magnitude of the body's speed as well as the direction in which the body is moving. As a result, the velocity of an object can provide us with the direction of motion of the body.

Acceleration can now be defined as the rate at which an object's velocity changes per unit time. The particle's velocity rises with time in the direction of acceleration. Again, if acceleration is perpendicular to velocity direction, the body moves in a circular route. As a result, acceleration can also indicate the direction of motion of a body.

The speed of the plane at the end of the runway is 59.065 m/s.

The equations of position and velocity in function of time of an object moving in a straight line together  constant acceleration are the following:

x = x₀ + v₀ · t + 1/2 · a · t²

v = v₀ + a · t

Where:

x = position of the plane at time t.

x₀ = initial position.

v₀ = initial velocity.

t = time.

a = acceleration.

v = velocity of the plane at time t.

If we place the origin of the frame of reference at the starting point, then x₀ = 0. Since the plane originate from rest, v₀ = 0. Then, the equation gets reduced to this:

x = 1/2 · a · t²

Let's find how much time it takes a plane to travel 500 m:

500 m = 1/2 · 6.99 m/s² · t²

2 · 500 m / 6.99 m/s² = t²

t = 8.45 s

Now, let's use the equation of velocity to solve the speed of the plane at t = 8.45 s (the time at which the plane is at the end of the runway):

v = v₀ + a · t    (v₀ = 0)

v = a · t

v = 6.99 m/s² · 8.45 s

v = 59.065 m/s

The speed of the plane at the end of the runway is 59.065 m/s.

The enthalpy of vaporization, commonly known as the heat of vaporization or heat of evaporation, is the amount of energy required to turn a liquid material into a gas. The enthalpy of vaporization depends on the pressure at which the transition occurs.

The heat of vaporization varies with temperature, yet for small temperature ranges and decreased temperature ranges, a constant heat of vaporization can be assumed. The heat of vaporization decreases with rising temperature until it totally disappears at a point known as the crucial temperature. The liquid and vapor phases are indistinguishable beyond the critical temperature, and the material is referred to as a supercritical fluid.

The acceleration of the car will be -5.68 m/s, and it travels 13.76 m before stopping.

Acceleration is the general term for any process where the velocity changes. There are only two ways to accelerate: either by increasing speed or decreasing direction, or both. The reason for this is that velocity includes both a speed and a direction.

You cannot possibly be accelerating if you don't also change your direction and speed, regardless of how swiftly you are travelling.

It is a vector quantity with m/s² as its SI unit.

According to the question, the given values are :

Initial speed, u=12.5 m/s,

Final speed, v=0 and,

Time, t=2.20 seconds.

Now by using equations of motion :

v= u+at

0=12.5 m/s+a(2.20 s)

a=-12.5/2.20

a= -5.68 m/s

Now distance traveled will be :

v²-u²= 2as

0-(12.5 m/s)²= 2(-5.68 m/s)²×s

s= -156.25/-11.36

By ideal gas approximation, container A has a higher temperature than container B.

where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.

From the question above, we know that

PA = PA

nA = 2nB

When the initial and final pressure is the same, we can use the ratio of moles and temperature as
