Answer: <u><em>C. Steel</em></u>

Explanation: <em><u>When a sound wave travels through a solid body consisting</u></em>

<em><u /></em>

<em><u>of an elastic material, the velocity of the wave is relatively</u></em>

<em><u /></em>

<em><u>high. For instance, the velocity of a sound wave traveling</u></em>

<em><u /></em>

<em><u>through steel (which is almost perfectly elastic) is about</u></em>

<em><u /></em>

<em><u>5,060 meters per second. On the other hand, the velocity</u></em>

<em><u /></em>

<em><u>of a sound wave traveling through an inelastic solid is</u></em>

<em><u /></em>

<em><u>relatively low. So, for example, the velocity of a sound wave</u></em>

<em><u /></em>

<em><u>traveling through lead (which is inelastic) is approximately</u></em>

<em><u /></em>

<em><u>1,402 meters per second.</u></em>

<em><u /></em>

Identify each statement that describes a benefit of the scientific method. (Select all choices that apply)
Alecsey [184]

The statements that describe a benefit of the scientific method are as follows:

  • It gives scientists a standardized way to approach a problem.
  • It reduces bias and judgment from personal experiences.
  • It gives scientists a common vocabulary for sharing information.

Thus, the correct options are B, C, and D.

<h3>What is the Scientific method?</h3>

The scientific method may be defined as a strategy of research in which a problem is recognized, relevant data is collected, a conjecture is composed of this data, and the assumption is empirically tested to determine the outcome of particular research.

The scientific method never explains or provides an answer to any question immediately because it consists of a scripted format with certain parameters.

The scientific method uses the identical vocabulary for sharing information with one another in particular terminology.

Therefore, it is well described above.

Is there a frame of reference one can go into that seems to eliminate gravity as Newton described it?
andriy [413]

Answer:

Yes such a frame exists: a free-fall (free-float frame) frame. This frame of reference is subject only to gravity and no forces such as electromagnetic forces or nuclear forces.

A camera is equipped with a lens with a focal length of 34 cm. When an object 2.4 m (240 cm) away is being photographed, what is
puteri [66]

Answer:

The magnification is -6.05.

Explanation:

Given that,

Focal length = 34 cm

Distance of the image =2.4 m = 240 cm

We need to calculate the distance of the object

\dfrac{1}{u}+\dfrac{1}{v}=\dfrac{1}{f}

Where, u = distance of the object

v = distance of the image

f = focal length

Put the value into the formula

\dfrac{1}{u}=\dfrac{1}{34}-\dfrac{1}{240}

\dfrac{1}{u}=\dfrac{103}{4080}

u =\dfrac{4080}{103}

The magnification is

m = \dfrac{-v}{u}

m=\dfrac{-240\times103}{4080}

m = -6.05

Hence, The magnification is -6.05.

A coyote can locate a sound source with good accuracy by comparing the arrival times of a sound wave at its two ears. Suppose a
il63 [147K]

Answer:

0.0000109261200583 s

0.0109261200583

Explanation:

d_2 = Distance from right ear = 3 m

s = Distance between ears = 15 cm

v = Speed of sound in air = 343 m/s

Distance between the left ear and the bird

d_1=\sqrt{s^2+d_2^2}\\\Rightarrow d_1=\sqrt{0.15^2+3^2}\\\Rightarrow d_1=3.00374765918\ m=3.004\ m

Time

t=\dfrac{Distance}{Speed}

Time difference would be

\Delta T=\dfrac{d_1}{v}-\dfrac{d_2}{v}\\\Rightarrow \Delta T=\dfrac{3.00374765918}{343}-\dfrac{3}{343}\\\Rightarrow \Delta T=0.0000109261200583\ s

The time difference is 0.0000109261200583 s

Time period is given by

T=\dfrac{1}{f}\\\Rightarrow T=\dfrac{1}{1000}\\\Rightarrow T=10^{-3}\ s

The ratio is

\dfrac{\Delta T}{T}=\dfrac{0.0000109261200583}{10^{-3}}\\\Rightarrow \dfrac{\Delta T}{T}=0.0109261200583

The ratio is 0.0109261200583
