Match each characteristic with the type of wave it corresponds to. Longitudinal waves Transverse waves The direction the wave tr

avels is parallel to the displacement of the medium. Electromagnetic waves are an example of this type of wave. Sound waves are an example of this type of wave. If the wave propagates in the x‑direction, the medium is also disturbed in the x‑direction. If the wave propagates in the x‑direction, the medium is disturbed in the y‑ and/or z‑direction. The direction the wave travels is perpendicular to the displacement of the medium.

Answer:

The properties are matched with the waves below;

Longitudinal :

  • The direction the wave travels is parallel to the displacement of the medium.
  • Sound waves are an example of this type of wave.
  • If the wave propagates in the x‑direction, the medium is also disturbed in the x‑direction

Transverse waves:

  • Electromagnetic waves are an example of this type of wave.
  • If the wave propagates in the x‑direction, the medium is disturbed in the y‑ and/or z‑direction.
  • The direction the wave travels is perpendicular to the displacement of the medium.

Explanation:

Longitudinal waves: These are waves in which the direction of propagation of waves is same as the direction of displacement of the medium. Examples are sound waves, seismic P waves and ultasound waves.

Transverse waves: These are waves in which the direction of propagation of waves is perpendicular to the direction of particle vibration. Examples are vibration on a spring, water waves, light waves.

Answer:The direction the wave travels is parallel to the displacement of the medium.LW.

Electromagnetic waves are an example of this type of wave. TW

Sound waves are an example of this type of wave.LW

Ir the wave propagates in the x‑direction, the medium is also disturbed in the x‑direction. LW

If the wave propagates in the x‑direction, the medium is disturbed in the y‑ and/or z‑direction. TW

The direction the wave travels is perpendicular to the displacement of the medium.TW

Explanación:

the main difference of Transversal AND Longitudinal waves (TW AND LW) is that the disturbation direction in the media with respect to the travel direction is well different for both cases. For TW the perturbation oscilatiew perpendicular to propagation direction of the wave.

In constrant for LW the disturbation oscilates in the same direction as the wave is propagating.

Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.8×106N , one an angle 11degrees west of north an
sp2606 [1]

Answer: 2,9 ×10¹⁰J.

Explanation:

1. The <em><u>work </u></em>is a measure of energy and is calculated as the product of the displacement times the parallel force to such displacement.

That means that the only components of the force that contribute to work are those that result parallel to the displacement.

2. Since it is given that the <em>two tugboats "pull the tanker a distance 0.83km toward the north"</em>, that is the displacement, and you have to calculate the net force toward the north.

3. <u>Tugboat #1</u>.

a) Force magnitude: F₁ = 1.8×10⁶N

b) Angle: α = 11° West of North

c) North component of the force F₁: Fy₁ = F₁cos(α) =  1.8×10⁶N  × cos(11°) = 1.77×10⁶N

4. <u>Tugboat #2</u>:

a) Force magnitude: F₂ = 1.8×10⁶N

b) Angle:  = 11° East of North

c) North component of the force F₂: Fy₂ = F₂cos(β) =  1.8×10⁶N  × cos(11°) = 1.77×10⁶N =

5. <u>Total net force, Fn</u>:

Fn = Fy₁ + Fy₂ = 1.77×10⁶N + 1.77×10⁶N = 3.54×10⁶N

6. <u>Work, W</u>:

Displacement, d = 0.83 km = 8,300 m

W = Fn×d = 3.54×10⁶N×8,300m = 29,000 ×10⁶J = 2,9 ×10¹⁰J

The answer is rounded to two significant figures because both data, Force and displacement, have two significant figures.

What is the force when an object exerts 15 pascal pressure on a square surface of side 5 meters
olga55 [171]

Answer:375N

Explanation:

pressure =15 pascal

Length of side =5 m

Area=length x length

Area=5 x 5

Area=25 m^2

Force=pressure x area

Force=15 x 25

Force=375N
