M A sinusoidal wave on a string is described by the wave function

Physics
1 answer:
vodomira [7]2 years ago
7 0

The power transmitted by the wave is 21.1 W.

<h3>Speed of the wave</h3>

The speed of the wave is determined from general wave equation as shown below;

y = A sin(ωt - kx)

where;

  • A is amplitude of the wave
  • ω is angular frequency
  • k is wave number

v = ω/k

given equation, y = = 0.15 sin (0.80x - 50t)

v = 50/0.8

v = 62.5 m/s

<h3>Power transmitted by the wave</h3>

P = ¹/₂μω²A²v

where;

  • μ is mass per unit length = 12 g/m = 0.012 kg/m

P = 0.5(0.012)(50²)(0.15²)(62.5)

P = 21.1 W

Thus, the power transmitted by the wave is 21.1 W.

If the prism is surrounded by a fluid, what is the maximum index of refraction of the fluid that will still cause total internal
larisa86 [58]

Answer:

n₁ > n₂.

prisms are made of glass with refractive index n₂ = 1.50, so the fluid that surrounds the prism must have an index n₁> 1.50

Explanation:

Total internal reflection occurs when the refractive index of the incident medium the light is greater than the medium to which the light is refracted, let's use the refraction equation

                 n₁ sin θ₁ = n₂ sin  θ₂

the incident medium is 1, at the limit point where refraction occurs is when the angle in the refracted medium is 90º, so sin θ₂ = 1

                 n₁ sin θ₁ = n₂

                 sin θ₁ = n₂ / n₁

We mean that this equation is defined only for n₁ > n₂.

In our case, for the total internal reflection to occur, the refractive incidence of the medium must be greater than the index of refraction of the prism.

In general, prisms are made of glass with refractive index n₂ = 1.50, so the fluid that surrounds the prism must have an index n₁> 1.50

Anders suffered a shock when his electric radio dropped into the bathtub--while anders was taking a bath. Anders argued that he
blsea [12.9K]

The claim Anders is most likely to make is the failure of the manufacturer to warn about such risk.

<h3>What is a Risk?</h3>

This is defined as the possibility of something bad happening and in this case it is electric shock when dropped into the bathtub.

Anders can decide to sue for not warning against risk of electric shock when in contact with water.

A ball of mass 0.10 kg moving at a speed of 3.0 m/s collides with a wall and bounces directly back with the same speed. If the b
alexdok [17]

The magnitude of the average force exerted on the ball by the wall is calculated below.

The average force exerted by the ball on the wall is 3 N

Explanation:

Given:

mass of the ball (m)=0.10 kg

speed (v) =3.0 m/s

time taken(t) =0.01 seconds

To calculate:

Average force(F) exerted by ball on the wall

We know;

F=(m×v)÷t

F=(0.10×3.0)÷0.01

<u><em>F=3 N</em></u>

Therefore the average force exerted by the ball on the wall is 3 N
