Which of the materials listed below would you select for the submarine's sonar detection panel and why?
Acoustic Impedances:
Material A: 20 MPa-s/m
Material B: 0.1 MPa-s/m
Material C: 2 MPa-s/m
a)Material B because it has the largest acoustic impedance mismatch with water and will reflect the most sound.
b)Material C because it has the smallest acoustic impedance mismatch with water and will transmit the most sound.
c)Material B because it has the smallest acoustic impedance mismatch with water and will transmit the most sound.
d)Material A because it has the largest acoustic impedance mismatch with water and will reflect the most sound.
e)Material C because it has the smallest acoustic impedance mismatch with water and will reflect the most sound.
f)Material A because it has the largest acoustic impedance mismatch with water and will transmit the most sound.
g)Material B because it has a lower acoustic impedance than water which will maximize the acoustic reflectance.

Answers

d) Material A because it has the largest acoustic impedance mismatch with water and will reflect the most sound. This will result in the best reflection of sound waves and improved sonar detection capabilities for the submarine.

What happens if the acoustic impedance of the material used for the sonar detector is too close to that of water?

If the acoustic impedance of the material used for the sonar detector is too close to that of water, it will result in a low reflection of sound waves. This can lead to a weaker return signal and reduced accuracy of the sonar system. The low reflection can also cause difficulty in distinguishing between the incoming and reflected sound waves, leading to errors in the data collected by the sonar system. In such a scenario, the sonar system may not be able to perform effectively and accurately. Thus, it is important to choose a material with an appropriate acoustic impedance that provides a sufficient mismatch with water for effective and accurate sonar detection.

A kangaroo can jump over an object 2.20 m high with a vertical speed of 6.57 m/s. how long is it in the air

Answers

The kangaroo is in the air for approximately 0.667 seconds.

What is the velocity?

Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.

A kangaroo with a vertical speed of 6.57 m/s may jump over an object 2.20 m high.

To find the time a kangaroo is in the air, we need to calculate the time it takes to reach the peak of its jump and then double that time (to account for both the ascent and descent).

We can use the formula for vertical motion under constant acceleration (g = 9.8 m/s²):

t = √(2h / g)

where h is the height of the jump (2.20 m) and g is the acceleration due to gravity (9.8 m/s²).

Plugging in the values, we get:

t = √(2 × 2.20 m / 9.8 m/s²)

t = √(0.447)

t ≈ 0.667 s

So the kangaroo is in the air for approximately 0.667 seconds.

Answers

The velocity will be 9.32 m/s.

The gravitational potential energy (Ug) of the satellite can be calculated using the formula where G is the gravitational constant (G = 6.67 x 10⁻¹¹ Nm²/kg²), Me is the mass of the Earth, M is the mass of the satellite, and r is the distance between the center of the Earth and the satellite.

At point a, the distance between the center of the Earth and the satellite is equal to a, so Ug can be calculated as:

Ug = -G x (Me x M) / a

At point b, the distance between the center of the Earth and the satellite is equal to b, so Ug can be calculated as:

Ug = -G x (Me x M) / b

The difference in gravitational potential energy between point a and point b is given by:

Ug(b) - Ug(a) = G x (Me x M) x (1/b) - This difference in potential energy is equal to the change in kinetic energy as the satellite moves from point a to point b, since the total energy of the system is conserved. The kinetic energy at point a can be calculated using the formula:

Ke = 0.5 x m x v0

where m is the mass of the satellite and v0 is the velocity of the satellite at point a. The velocity can be calculated using the equation of motion for a satellite in orbit:

Answers

When you honk your horn while driving 80 km/h, your friend standing on the sidewalk hears a frequency of 340 Hz.

This is due to the Doppler Effect, which causes a change in frequency for a sound wave as it approaches or moves away from an observer. As you drive towards your friend, the frequency of the horn increases, and as you drive away from them, the frequency decreases. This shift in frequency is proportional to the relative speed between the source of the sound and the observer. The change in frequency can be calculated using the equation: f' = f × (v ± v0) / (v ± v s), where f' is the observed frequency, f is the emitted frequency, v0 is the speed of sound in air, v is the relative speed between the source and observer, and vs is the speed of the source.

Answers

Dorsal (i.e., posterior) refers to the back region of the human body. So the correct term used is posterior.

Why is it called Dorsal?

Dorsal (anatomy), an anatomical phrase of location refers to the back or upper side of an organism or sections of an organism (from Latin dorsum 'back').To describe the anatomy of animals, including humans, standard anatomical words of location are utilised. The phrases, which are often derived from Latin or Greek roots, describe an object in its normal anatomical position. This position defines what is in front ("anterior"), behind ("posterior"), and so on. The body is defined using anatomical planes and anatomical axes as part of defining and characterising concepts.

The meaning of words can vary depending on whether an organism is bipedal or quadrupedal. Furthermore, some phrases may have no meaning at all for other creatures, such as invertebrates; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a component is close to the middle ("proximal") or distant from the middle ("distal") ("distal").

The postulate that "the collision of one particle with another (or with the wall) is completely elastic" breaks down under conditions of high pressure. At high pressures, the number of molecules per unit volume decreases, so that the spacing between the particles is reduced and the volume of the gas particles becomes more significant.

As the pressure increases, the gas particles collide with more force and for longer periods, causing some energy to be transferred between the particles, making the collisions less elastic. This can result in a loss of kinetic energy and an increase in the internal energy of the gas, leading to a deviation from ideal gas behavior. Pressure is a measure of force per unit area and is defined as the force applied to a surface divided by the area of the surface. It is a scalar quantity and is expressed in units of force per unit area, such as pascals (Pa), atmospheres (atm), or pounds per square inch (psi). Pressure can be exerted by a fluid, such as a gas or liquid, and is transmitted equally in all directions.

If on September 14 the Moon is full and is near Famous Star Spica, when will the Moon next be near Spica? (Give your answer as the number of days after the full Moon on September 14.)

When will it next be full? (Give your answer as the number of days after the full Moon on September 14.)

Are these values the same? Why or why not?

Answers

The Moon will next be near Spica approximately 29.5 days later. This is because the Moon orbits the Earth once every 29.5 days, which is known as its synodic period.

The next full Moon will occur approximately 29.5 days after the full Moon on September 14.

How does the moon orbit?

These values are not the same because the phases of the Moon are not dependent on its position relative to other celestial objects. The time it takes for the Moon to complete one full cycle of phases, from full to full, is 29.5 days.

Meanwhile, the time it takes for the Moon to return to the same position relative to Spica is slightly different and can be calculated using the sidereal period of the Moon, which is 27.3 days.
