the fundamental frequency for the 3rd chord on a five-string guitar is 240 Hz. what frequency would produce the 10th harmonic?

Mamont248 [21]

The frequency of the 10th harmonic is 800 Hz

Explanation:

The frequency of the nth-harmonic for the standing waves in a string is given by the equation

$f_n = n f_1$

where

$f_1$ is the fundamental frequency of the string

In this problem, we are given the frequency of the 3rd harmonic:

$f_3 = 240 Hz$

Which can be rewritten in terms of the fundamental frequency

$f_3 = 3 f_1$

So we find $f_1$ :

$f_1 = \frac{f_3}{3}=\frac{240}{3}=80 Hz$

Now that we have the fundamental frequency, we can find the frequency of the 10th harmonic, with n = 10 :

$f_{10} = 10f_1 = (10)(80)=800 Hz$

The car A has a weight of 4000 lb and is traveling to the right at 3 ft/s. Meanwhile a 2000 lb car B is traveling at 6 ft/s to t

iVinArrow [24]

To solve this problem we should apply Newton's third law for which it is defined that there must be an equal reaction in the opposite direction.

From this law, if Car A generates a force on car B, that car must have opposed a force exactly the same but in the opposite direction. The car A moved to the left and generates a force of 900lb so the magnitude of the force in the car B is also 900lb but to the right (opposite direction to the first car)

The correct option is 900lb to the right.

A good-quality measuring tape can be off by 0.42 cm over a distance of 28 m. What is its percent uncertainty? (Express your answ

Alecsey [184]

Answer:

0.015%

Explanation:

Data provided in the question:

Length by which the measuring tape can be off, δL = 0.42 cm

Total measured length for which Error of δL is observed, L = 28 m

Now,

we know,

1 m = 100 cm

Thus,

28 m = 28 × 100 = 2800 cm

Percent uncertainty = [δL ÷ L] × 100%

= [0.42 ÷ 2800] × 100%

= 0.015%

A 2.5g copper penny is given a charge of -4.0*10^-9c. how mny excess electrons are on the penny?

Lyrx [107]

Answer : The excess of electrons on the penny are, $2.5\times 10^{10}$ electrons

Solution : Given,

Total charge = $-4.0\times 10^{-9}C$

Charge on electron = $-1.6\times 10^{-19}C$

Formula used :

$\text{Excess of electrons}=\frac{\text{Total charge}}{\text{Charge of electron}}$

Now put all the given values in this formula, we get the excess of electrons present on the penny.

$\text{Excess of electrons}=\frac{\text{Total charge}}{\text{Charge of electron}}=\frac{-4.0\times 10^{-9}C}{-1.6\times 10^{-19}C/e^-}=2.5\times 10^{10}e^-$

Therefore, the excess of electrons on the penny are, $2.5\times 10^{10}$ electrons
