navik [9.2K]

Answer:

d. the same within the uncertainty of each measurement method

Explanation:

The density of an object and in general any physical property, has the same value regardless of the method used to measure it, either directly or indirectly. Since two completely different valid methods are used, the results must be the same, taking into account the level of precision of each of the methods.

for the primitive yo-yo in fig, to find the downward acceleration of the cylinder and the tension in the string. you can take th
mixas84 [53]

The downward acceleration of the solid cylinder at the given tension in the string is determined as 2Tr/MR.

<h3>Downward acceleration of the cylinder</h3>

The downward acceleration of the solid cylinder is determined from the principle of conservation of angular momentum as shown below;

Iα = Tr

where;

  • I is moment of inertia of the solid cylinder
  • α is angular acceleration of the cylinder
  • T is tension in the string
  • r is length of the string

α = Tr/I

\frac{a}{R} = \frac{Tr}{I} \\\\\frac{a}{R} = \frac{Tr}{\frac{1}{2} MR^2}\\\\\frac{a}{R} =\frac{2Tr}{MR^2} \\\\a = \frac{2Tr}{MR}

where;

  • a is the downward acceleration of the solid cylinder
  • R is radius of the cylinder

Thus, the downward acceleration of the solid cylinder at the given tension in the string is determined as 2Tr/MR.

which statement is true of a wave that's propagating along the pavement and girders of a suspension bridge?
Blizzard [7]

<u>Question:</u>

Which statement is true of a wave that’s propagating along the pavement and girders of a suspension bridge?

A. The wave is mechanical, with particles vibrating in a direction that is parallel to that of the wave, forming compressions and rarefactions.

B. The wave is electromagnetic, with particles vibrating in a direction that is parallel to that of the wave, forming compressions and rarefactions.

C. The wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming crests and troughs.

D. The wave is electromagnetic, with particles vibrating in a direction that is perpendicular to that of the wave, forming crests and troughs.

E. The wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions.

Answer:

The statement “The wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave forming compressions and rarefactions” is true of a wave that’s propagating along the pavement and girders of a suspension bridge.

<u>Explanation: </u>

As it is stated about the wave propagates in the given question, the first thing to confirm is the wave should be a mechanical wave as electromagnetic wave will not penetrate the suspension bridge.

Then as both the pavements and girders are rigid structures present in suspension bridge, the wave can propagate in them which are forming compressions and rarefactions.

The transverse waves cannot pass through them because of the polarization property of transverse waves. Also as they propagate in compression and rarefactions mode, the particles will tend to vibrate only in perpendicular direction to that of the wave propagation. So, the last statement is only true.
