Explanation:

Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.

Answer:

Snell's law of refraction also known as the second law of refraction which states:

The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant or given pair of Media .

1. A huge spool of wire, 10,000 meters long, weighs 81.34 N. You cut off a meter or so and tie it between two posts, 0.660 m apa

WARRIOR [948]

Answer:

The beat frequency is 6.378 Hz.

Explanation:

Given that,

Length of wire = 10000 m

Weight = 81.34 N

Distance = 0.660 m

Tension = 52 N

Frequency = 196 Hz

We need to calculate the mass of the wire

Using formula of weight

$W= mg$

$m = \dfrac{W}{g}$

Put the value into the formula

$m=\dfrac{81.34}{9.8}$

$m=8.3\ kg$

The mass per unit length of the wire

$m_{l}=\dfrac{m}{l}$

Put the value into the formula

$m_{l}=\dfrac{8.3}{10000}$

$m_{l}=8.3\times10^{-4}\ kg/m$

We need to calculate the frequency in the wire

Using formula of frequency

$f_{w}=\dfrac{1}{2l}\sqrt{\dfrac{T}{m_{l}}}$

Put the value into the formula

$f_{w}=\dfrac{1}{2\times0.660 }\sqrt{\dfrac{52}{8.3\times10^{-4}}}$

$f_{w}=189.62\ Hz$

We need to calculate the beat frequency

Using formula of beat frequency

$f_{b}=f_{in}-f_{w}$

Put the value into the formula

$f_{b}=196-189.622$

$f_{b}=6.378\ Hz$

Hence, The beat frequency is 6.378 Hz.

Explain why liquids flow but solids do not.

goldfiish [28.3K]

Because they have no dignified shape they take on the shape of whate ever container they are in and when you pour in out it can't really take any shape except tho lay flat on the table. and solids do not flow because they have a dignified shape. hope it helps!

When electric current is flowing in a metal, the electrons are movinga. at nearly the speed of light.b. at the speed of sound in

yaroslaw [1]

Answer:

Option (d)

Explanation:

The electrons in a conductor moves with the drift velocity when the electric current is flowing through the conductor.

The drift velocity is due to the applied electric field across the conductor.

What the heck is friction

Anuta_ua [19.1K]

Answer:

Explanation:

Friction is a force that makes an object slow down. Not speed up, cause it to move, or occurs in a vacuum. Friction is often caused by the surface an object is moving on.
