Finding spring constant given displacement of spring and distance traveled by a cart

1 answer:

5 0

- (spring constant) (new length of spring - original length of spring) = Force applied to spring.
that is
-kx=F

Did you only have how far the cart traveled? No mass or acceleration or speed or time taken?

A tuning fork is held over a resonance tube, and resonance occurs when the surface of the water is 12 cm below the top of the tu

Rainbow [258]

Answer:

786 Hz

Explanation:

Recall, the speed of sound is

v = 332 + 0.6t

Where t = 23°

v = 332 + 0.6(23)

v = 332 + 13.8

v = 345.8 m

Also, it is known that distance between two consecutive resonance length is half of the wavelength.

L2 - L1 = λ/2

34 - 12 = λ/2

λ/2 = 22

λ = 44 cm

Finally, remember that also

Frequency = speed/ wavelength

Frequency = 345.8/0.4

Frequency = 786 Hz

Therefore, the frequency of the tuning fork is 786 Hz

The low-frequency speaker of a stereo set has a surface area of and produces 1W of acoustical power. What is the intensity at th

AlekseyPX

Answer:

I = $\frac{1}{4\pi \ r^2}$

we see the intensity decreases with the inverse of the distance squared

Explanation:

Intensity is defined as power per unit area,

I = P / A

in this case we have that the sound is emitted in a spherical form therefore the area is

A = 4 pi r2

therefore the intensity is

I = $\frac{1}{4\pi \ r^2}$

as we see the intensity decreases with the inverse of the distance squared
