2. A 1.30-m long gas column that is open at one end and closed at the other end has a fundamental resonant frequency 80.0 Hz. Wh
Elina [12.6K]

To solve this problem, it will be necessary to apply the concepts related to the fundamental resonance frequency in a closed organ pipe.

This is mathematically given as

f_n (2n+1)(\frac{v}{4L})

For fundamental frequency n is 0, then,

f_0 = \frac{v}{4L}

When,

v = Velocity of sound

L = Length,

Rearranging to find the velocity,

v = f_0 (4L)

v = (80Hz)(4)(1.3m)

v = 416m/s

Therefore the speed of sound in this gas is 416m/s

A particle accelerator fires a proton into a region with a magnetic field that points in the x-direction. (a) If the proton is m
iVinArrow [24]

Answer:

<em>The magnitude of the magnetic field will act in a direction towards me.</em>

<em></em>

Explanation:

When a charged particle enters a magnetic field, it is deflected. The direction of travel of the particle is deflected, but the kinetic energy of the particle is not affected. <em>The force experienced by a charged particle as it enters a magnetic field that acts perpendicular to the path of the velocity of the particle, will produce a force that is perpendicular to both the direction of travel of the particle and the direction of the magnetic field.</em> In this case, the proton moves in the y-direction, the magnetic field is in the x-direction, therefore the force experienced by the particle will be towards me.

Who pays the income tax, the payroll tax, the estate and gift taxes? Who bears the burden of the gasoline and tobacco taxes? If Congress were to raise this tax rate, or lower that tax deduction, who would gain and who would lose? The outcomes of the political battles over changes in the tax system often hinge on the answers to such questions. This paper will discuss the economic consequences of taxation and the factors that influence where the burden of various taxes really falls. It will review some of the discussions in the economic literature. Finally, it will suggest that a shift to a markedly different type of tax system would benefit all players in the economy.

You do a certain amount of work on an object initially at rest, and all the work goes into increasing the object’s speed. If you
EleoNora [17]

Answer:

\sqrt{2}v

Explanation:

The work done on the object at rest is all converted into kinetic energy, so we can write

W=\frac{1}{2}mv^2

Or, re-arranging for v,

v=\sqrt{\frac{2W}{m}}

where

v is the final speed of the object

W is the work done

m is the object's mass

If the work done on the object is doubled, we have W' = 2W. Substituting into the previous formula, we can find the new final speed of the object:

v'=\sqrt{\frac{2W'}{m}}=\sqrt{\frac{2(2W)}{m}}=\sqrt{2}\sqrt{\frac{2W}{m}}=\sqrt{2}v

So, the new speed of the object is \sqrt{2}v.
