What happens when you stroke the prongs with the wire?

1 answer:

8 0

When you stroke the prongs with a wire, a static sound is being produced. This kind of minimum-information noise is called white noise, by analogy with white light which is a uniform mixture of all the different possible colors. Hope this helps.

Two Sets of solid double yellow lines with spaced two or more feet apart indicates that Do not drive on or over the barrier.

<h3>What are the line colors in lane control?</h3>

Solid yellow lines - it is marked at the center of a road and used for two-way traffic.

Broken yellow lines - It indicate that you may pass if the broken line is next to your driving lane.

Two solid yellow lines - It indicates no passing or Do not drive on or over the barrier.

Two sets of solid double yellow lines are considered a barrier , make a left turn, or a U-turn to cross it.

An object of mass 3.4 kg is moving in a straight line with kinetic energy 59.177 J. A force is applied in the direction of its m

rusak2 [61]

Answer:

Its momentum is multiplied by a factor of 1.25

Explanation:

First, we calculate the initial velocity of the object:

K = 0.5 * m * v₁²

59.177 J = 0.5 * 3.4 kg * v₁²

v₁ = 5.9 m/s

With that velocity we can calculate the initial momentum of the object:

p₁ = v₁ * m

p₁ = 20.06 kg·m/s

Then we calculate the velocity of the object once its kinetic energy has increased:

(59.177 J) * 1.57 = 0.5 * 3.4 kg * v₂²

v₂ = 7.4 m/s

And calculate the second momentum of the object:

p₂ = v₂ * m

p₂ = 25.16 kg·m/s

Finally we calculate the factor:

p₂/p₁ = 1.25

Explain how a guitar produces sound by using the terms standing waves and resonance.

Rzqust [24]

When an object is forced into resonance vibrations at one of its natural frequencies, it vibrates in a manner such that a standing wave is formed within the object. ... such patterns are only created within the medium at specific frequencies of vibration.
