Rachel collected data on the speed of sound waves passing through different media.

Physics
1 answer:
Helga [31]2 years ago
7 0

The conclusion is, medium Q is most likely a solid because solids have the highest density and sound waves travel fastest in high density media.

<h3>Effect of density on speed of sound</h3>

Sound wave is mechanical wave that requires material medium for its propagation.

A high dense medium, is a medium with closely packed molecules. Since sound wave requires material medium for its propagation, it will travel faster in a high dense medium than a less dense medium.

Thus, the speed of sound increases as the density of the medium increases.

<h3>Speed of sound in the different media</h3>

The conclusion that can be made from the speed of sound in the different media is "Medium Q is most likely a solid because solids have the highest density and sound waves travel fastest in high density media".

A jet aircraft with mass of 658,055 kilograms is flying straight downward. At an instant the plane's engine is producing an down
sdas [7]

Answer:

The acceleration of the plane is 10.93 m/s² at that instant.

Explanation:

Given:

Mass of aircraft, m=658055\textrm{ kg}

Downward thrust produced, F=1484732.5\textrm{ N}

Upward resistance force by air, F_{R}=740492.6\textrm{ N}

Weight of the aircraft acting donward, W=mg=658055\times 9.8=6448939\textrm{ N}

According to Newton's second law, net force acting on an object is equal to the product of mass and its acceleration.

Here, the net force is given as the difference of downward forces and upward forces.

F_{net}= F+W-F_{R}\\ F_{net}=1484732.5+6448939-740492.6=7193178.9\textrm{ N}

Now,

F_{net}=ma\\7193178.9=658055a\\a=\frac{7193178.9}{658055}=10.93\textrm{ }m/s^{2}

Therefore, the acceleration of the plane is 10.93 m/s² at that instant.

Svetradugi [14.3K]

Answer:

The answer to your question is Power = 24 Watts

Explanation:

Data

time = 3 s

Work = 72 J

Power = ?

Power is defined as the rate at which a work is done.

Formula

Power = Work / time

-Substitution

Power = 72/3

-Simplification

Power = 24 Watts

-Conclusion

The Power exerts by 72 J of work in 3 seconds is 24 watts.
