The highest frequency sound to which the machine can be adjusted is :

Given data :

Pressure = 10 Pa

Speed of sound = 344 m/s

Displacement altitude = 10⁻⁶ m

applying the formula below

Pmax = [tex]B(\frac{2\pi f}{v}) A[/tex] --- ( 1 )

Therefore :

f = ( Pmax * V ) / [tex]2\pi \beta A[/tex]

 = ( 10 * 344 ) / 2[tex]\pi[/tex] * 1.31 * 10⁵ * 10⁻⁶

A loud factory machine produces sound having a displacement amplitude in air of 1.00 μm, but the frequency of this sound can be adjusted. In order to prevent ear damage to the workers, the maximum pressure amplitude of the sound waves is limited to 10.0 Pa. Under the conditions of this factory, the bulk modulus of air is 1.31×105 Pa.

Answer: 0.0196 Newtons (0.0196N)

Explanation:

Weight is the test mass multiplied by the gravitational field created from the source mass. The source mass is the Earth, and the test mass is the computer chip:

[tex]W=mg[/tex]

[tex]W=(0.002kg)(9.8m/s^2)[/tex]

[tex]W=0.0196N[/tex]

Answer:

The greater the amplitude of a wave, the ( less/more ) energy it is transferring.

The more energy; so that means less would be the incorrect word

As waves spread out from a source, the energy they transfer gets more ( concentrated/ spread out )

Spread out; so that means concentrated would the be the incorrect word

and so the amplitude of the waves gets ( larger/ smaller)​

Smaller; so that means larger is the incorrect word

Answer:

44.4 m/s

Explanation:

The statement that best explains this difference is "As the block is moving across the table, friction will affect the block’s motion and thus could account for the difference" (option A).

In physics, friction can be defined as a force of resistance that occurs when an objects moves above a surface or above another object. Friction can be classified in four types:

This force opposes the movement of the object and therefore it can affect the velocity of the object by decreasing it. Based on this, it is likely that the difference in the calculation is because of friction as this was not considered (option A).

Note: This question is incomplete; here is the missing section:

A. As the block is moving across the table, friction will affect the block’s motion and thus could account for the difference.

B. It is possible that a small amount of the original block was lost during the explosion.

C. When the student did the calculation, the student assumed that the explosion occurred just as the block reached the origin. The difference in velocity could be due to the explosion occurring either just before or just after the origin.

D. The explosion created a force that affected the experiment.

E. Conservation of momentum is not the correct equation to apply to the explosion, since the two pieces apply forces to each other.

Answer:

The difference between the calculated and measured velocity of the piece of mass m2 can be attributed to several factors. Here are a few possible explanations:

1. Measurement error: It's possible that there were errors or inaccuracies in the measurements taken by the motion sensor. This could include issues with the sensor itself, calibration errors, or human error in recording the data.

2. Friction and air resistance: The experiment assumes an ideal scenario where there are no external forces acting on the block and the resulting fragments. However, in reality, there may be friction and air resistance present, which can reduce the velocity of the pieces after the explosion. These factors were not accounted for in the conservation of momentum calculations.

3. Internal forces: The explosion of the block into two pieces involves internal forces between the fragments. These forces may not be completely accounted for in the conservation of momentum analysis. If there are significant internal forces acting during the explosion, they could reduce the calculated velocity of the piece of mass m2 compared to the measured value.

4. Incomplete information: It's possible that there is additional information or factors that were not considered in the given description of the experiment. Without knowing all the details, it's challenging to pinpoint the exact reason for the discrepancy between the calculated and measured velocity.

In summary, the most likely explanation for the difference between the calculated and measured velocity of the piece of mass m2 is measurement error or the presence of external forces (such as friction and air resistance) and internal forces (during the explosion) that were not accounted for in the analysis.

Due to stronger cohesive than adhesive forces mercury levels falls in a capillary tube. However, water level rises in a capillary tube due to greater adhesive than cohesive forces.

Capillary action refers to the rise or fall of a liquid in a narrow tube.

The height to which a liquid is depressed or rises in a narrow tube depends on the strength of the cohesive forces of the molecules of the fluid compared to the adhesive forces between the molecules of the fluid and the walls of the tube.

In water, the adhesive forces between the walls of the tube and water molecules is greater than the cohesive forces between water molecules, hence water rises in a capillary tube.

In mercury the adhesive forces between the walls of the tube and water molecules is less than the cohesive forces between mercury molecules, hence mercury levels falls in a capillary tube.

Explanation:

If a capital letter R is seen in an ordinary mirror, it will look like option D. The correct option is D.

Something that is reversed with respect to a previous instance of the same thing, or with respect to a plane or axis in between. The best illustration of a virtual image is a reflection in a mirror.

Real images are created by intersecting rays, and virtual images are created by diverging rays. A mirror creates a virtual image by reflecting a real image (blue) back to the viewer (red), giving the impression that the items in the image are behind the mirror's surface and facing the other way (purple).

The R in the mirror will look vertically inverse. The types of mirrors are plane mirrors, rotating mirrors, inclined mirrors, and spherical mirrors.

Therefore, the correct option is D.

Explanation:

lost some electrons I think

This is because no battery or energy storage device is 100% efficient, meaning that some of the energy that goes into charging the battery is lost as heat or other forms of energy during the charging process.

This loss of energy is due to several factors, including resistance in the battery's electrical components, chemical reactions that occur within the battery during charging, and other inefficiencies in the charging process.

As a result, when the battery is discharged, it cannot release all the energy that was originally put into it during charging, and some of the energy is lost as heat or other forms of energy. This is known as energy loss or energy dissipation, and it is a common occurrence in all types of energy storage systems.

Answer:

0.065 seconds

Explanation:

i) Change in momentum is equal to impulse so, m(v-u) = ft  (Where f is force and t is time)

ii) Since we know the mass of the ball, we change grams to the SI unit of kilograms, kg so 0.057kg

iii) We are also told that the ball CHANGES direction, so we know that the new velocity is the negative value of the initial one,

iv) Putting this all together we get 0.057(25--15) which is the same as 0.057(25 + 15)

v) We get an impulse of 2.28 Ns

vi) We take this value and divide it by 35 as we want the Force alone and not the time,
