As ocean waves approach shore, their velocity decreases. How does a decrease in velocity affect the frequency and wavelength of

timama [110]

Explanation:

As ocean waves approach shore, their velocity decreases. The relation between the velocity, wavelength and the frequency of a wave is given by :

$v=f\times \lambda$

f = frequency

$\lambda$ = wavelength

$f=\dfrac{v}{\lambda}$ ..............(1)

So, as the velocity of the wave increases, the wavelength and frequency also increases as per equation (1). When the velocity decreases, the frequency and the wavelength also decreases.

A circular loop of wire with 15 turns, radius 0.129 m and resistance 0.251 Ohms is connected to a 16.7 V power supply. The magne

Licemer1 [7]

The magnetic field at the center of the circular loop is 3.24 x 10⁻⁴ T.

<h3>Current in the wire</h3>

The current in the wire is calculated as follows;

V = IR

I = V/R

I = 16.7/0.251

I = 66.53 A

<h3>Magnetic field at the center of the loop</h3>

The magnetic field at the center of the circular loop is calculated as follows;

$B = \frac{\mu_0 I}{2R} \\\\B = \frac{4\pi \times 10^{-7} \times66.53 }{2\times 0.129} \\\\B = 3.24 \times 10^{-4} \ T$

Suppose you have an unknown clear substance immersed in water, and you wish to identify it by finding its index of refraction. Y

jek_recluse [69]

When light passes from one medium to another at an angle, it may refract, or bend, according to Snell's law:

n₁sin(θ₁) = n₂sin(θ₂)

n₁ = index of first medium, θ₁ = angle of incidence, n₂ = index of second medium, θ₂ = angle of refraction

Given values:

n₁ = 1.33 (water), θ₁ = 45.0°, θ₂ = 40.3°

Plug in and solve for n₂:

1.33sin(45.0°) = n₂sin(40.3°)

n₂ = 1.454

I looked up this value on the HyperPhysics indices of refraction table... The index we calculated is closest to 1.46, which is that of fused quartz.

Brut [27]

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Below are the chocies:

Hasty generalizations are made
One tries to deduce a conclusion from false premises
One has a large enough sample set of data on which tobase inductions
Data cannot support the claims made for the logicalreasoning
<span>One tries to work out syllogisms

I think the answer is </span>One has a large enough sample set of data on which tobase inductions
