The wave itself, that is, the crests and troughs, will move along the direction of propagation, but the particles themselves will only move perpendicularly to it.

How does a transverse wave rope move?

A wave in which the displacement of the medium's particles is perpendicular to the direction of energy transfer is called a transverse wave. If a rope is stretched out horizontally and the end is vibrated back and forth vertically, a transverse wave can be produced in the rope.

Transverse wave propagation is only feasible via solids; it is not possible in liquids or gases. Only transverse waves can display the polarization phenomena. The plane of vibration or polarization is the location where all of the particle vibration in a medium occurs. Shaking the rope causes the rope's constituent parts to oscillate, which causes the wave to advance or retreat from the energy source. The rope moves at a straight angle—or perpendicular—to the direction that the wave moves.

So the net force acting on the tanker is: F_net = sqrt(Fx^2 + Fy^2) = 2.4 x 10^4 N And the acceleration of the tanker is: a = F_net / m = 2.4 x 10^4 N / 3.3 x 10^7 kg = 7.27 x 10^-4 m/s^2.

How to calculate net force and acceleration?

To find the acceleration of the tanker using vector methods, we can use the following equation:

F_net = ma

where F_net is the net force acting on the tanker, m is the mass of the tanker, and a is the acceleration of the tanker.

In this case, the two tugboats are pulling in opposite directions, so we need to find the vector sum of their forces to find the net force acting on the tanker.

Using the component method, we can find that the x-component of the net force is:

Fx = 2.4 x 10^4 N * cos(16) - 2.4 x 10^4 N * cos(9) = -2.4 x 10^4 N

and the y-component of the net force is:

Fy = 2.4 x 10^4 N * sin(16) + 2.4 x 10^4 N * sin(9) = 0 N

So the net force acting on the tanker is:

F_net = sqrt(Fx^2 + Fy^2) = 2.4 x 10^4 N

And the acceleration of the tanker is:

a = F_net / m = 2.4 x 10^4 N / 3.3 x 10^7 kg = 7.27 x 10^-4 m/s^2

The water is converted to ice at 0 degrees Celsius

The heat of fusion for water to be Lf = 3.34*10^5 J/kg.

Let heat released from ice = Qc

Heat absorbed by water = Ql

We know that Ql = mLf = 76.3 x 3.34*10^5 = 2.54*10^4kJ

The time period of a mass-spring system is written as: T = 2π√m/k where m is the mass of system and k is spring constant.

The gravitational acceleration is defined as: g = GM/r^2

AS the acceleration due to gravity on planet X is greater than that of on earth we know that the time period is inversely proportional to g.

Answer:

One possible reason is that change in velocity is greater for the individual with lower mass.

Explanation:

By Newton's Law of Mechanics, magnitude of the force on two players would be the same in the collision. Let [tex]F[/tex] denote this magnitude.

Assume that the duration of the collision is [tex]\Delta t[/tex]. In this collision, magnitude of the impulse [tex]J[/tex] on each player would be the same: [tex]J = F\, \Delta t[/tex].

At the same time, impulse is equal to the change in momentum. Specifically, if the mass of one player is [tex]m[/tex] and the change in their velocity is [tex]\Delta v[/tex], the change in their momentum would be [tex]m\, \Delta v[/tex]. Thus:

[tex]m\, \Delta v = J = F\, \Delta t[/tex].

Rearrange to obtain an expression for the change in velocity:

[tex]\begin{aligned}\Delta v &= \frac{J}{m} = \frac{F\, \Delta t}{m}\end{aligned}[/tex].

In other words, in this collision, change in velocity is inversely proportional to the mass of the participant. Hence, even though the two players experienced force of the same magnitude, the participant with a lower mass would experience a greater change in velocity.

The magnitude of the average electric field in between the two points is 480V/m

Electric field is an important concept in physics that describes the force exerted by a charged particle or object on other particles or objects in its vicinity. It is a vector field, meaning it has both magnitude and direction. The electric field is created when an electric charge is placed in a region of space. The electric field will then act on any other charges in the region, producing a force on them.

Electric field (E) is defined as the electric potential difference (V) divided by the distance (d) between two points:
E = V / d
In this case, the electric potential difference is 120V and the distance between the two points is 0.25m. Therefore, the magnitude of the average electric field in between the two points is:
E = 120V / 0.25m = 480V/m

Newton's second law defines the relationship between force and acceleration. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object.

Mathematically, Newton's second law states that force is the multiplication of mass and acceleration:

To find the acceleration of the coin relative to the cab, we can use the equation for tension force:

Tension force = mass x acceleration

We are given the tension force (12.0 kN) and the combined mass of the cab and its occupant (1450 kg). Therefore, we can solve for acceleration:

12.0 kN = (1450 kg) x acceleration

acceleration = 12.0 kN / (1450 kg)

acceleration = 0.00828 m/s^2

So the acceleration of the coin relative to the cab is 0.00828 m/s^2

It is worth noting that the coin will fall with respect to the elevator with an acceleration of 9.8 m/s^2 (upwards) but relative to the elevator, the coin is accelerating downwards with 9.8 m/s^2 + 0.00828 m/s^2 = 9.80828 m/s^2.

The balloon needs to be charged with a minimum of 1.3 x 10-10 Coulombs for it to adhere to the wall.

To find the minimum amount of charge required on the balloon for it to stick to the wall, we can use the following equation:

Friction force = friction coefficient x normal force

The electrical attraction between the charged balloon and the molecules of the wall, which cause an equal but opposing charged polarization, produces the normal force and may be computed as follows:

Normal force = k x q1 x q2 / r^2

where k is Coulomb's constant, q1 and q2 are the charges on the balloon and the wall's molecules, respectively, and r is the average distance between the opposite charges.

The gravitational force acting on the balloon is given by:

Fg = m x g

Since the downward gravitational force is balanced by the upward static friction force, we can set the gravitational force equal to the friction force:

m x g = friction coefficient x k x q1 x q2 / r^2

Solving for q1, the charge on the balloon, we have:

q1 = (m x g x r^2) / (friction coefficient x k x q2)

Given that the mass of the balloon is 1.4 g, coefficient of static friction with the wall is 0.73, the average distance between the opposite charges is 0.75mm, and Coulomb's constant is 910^9 Nm^2/C^2.

q1 = (1.4 x 9.8 x (0.75 x 10^-3)^2) / (0.73 x 9 x 10^9)
