what information does a ship's sonar device use to determine the distance to the ocean?
a. the speed of sound in water and the time it takes for a signal to return
b.the temperature of the water and the temperature of the air above it
c.the composition of the ocean floor and the temperature of water near the ocean floor
d.the composition of the ocean floor and the temperature of water near the ocean floor
( i know there are two of the same answers but um that's how it was so....)

Answers

Answer 1
C would be the answer to that
Answer 2
the answer is a), it uses sound waves to bounce of the ocean floor and it calculates the time it takes for the waves to come back up. They then can figure out the depth by using this

if the same amount of heat is added to 25.0g samples of each of the metals in the chart, which metal will experience the largest temperature change?
a. calcium
b. iron
c.silver
d.gold

Answers

i think iron? i’m not 100% sure

Gold metal will experience the largest temperature change.

Explanation:

Given:

Four different metals of 25.0 gram in which the same amount of heat was added.

To find:

Which metal will experience the largest temperature change.

Solution

Consider heat added to all metals be Q and the mass of every metal is 25 grams. This means the value of temperature change will be dependent on value specific heat of metals.

The change in temperature of the substance when heat is supplied to the substance is given by:

[tex]Q=m\times c\times \Delta T\\\Delta T=\frac{Q}{mc}\\\Delta T\propto \frac{1}{c}....[1][/tex]

The above relation means that change in temperature is inversely proportional to the specific heat of the metal.

The specific heat of calcium =[tex]c_{Ca}=0.647 J/g^oC[/tex]

The specific heat of iron = [tex]c_{Fe}=0.449 J/g^oC[/tex]

The specific heat of silver = [tex]c_{Ag}=0.235 J/g^oC[/tex]

The specific heat of gold =[tex]c_{Au}=0.129 J/g^oC[/tex]

[tex]c_{Au}<c_{Ag}<c_{Fe}<c_{Ca}[/tex]

So, out of these metals, gold has the lowest value of specific heat and according to relation (1), the temperature change will be largest in 25.0 grams of gold and will be least in calcium.

The order of change in temperature of the metals will be:

[tex]\Delta T_{Au}>\Delta T_{Ag}>\Delta T_{Fe}>\Delta T_{Ca}[/tex]

Gold metal will experience the largest temperature change.

The student develop the model above ( its really below) . usually the model, identify two potential wave phenomena that occur and are the reason behind why the student can only hear the train in front of the apartment complex.
A. the train can be heard more easily in front of the apartment complex because of reflection and interference. as the sound comes from train, the sound waves reflect off of the complex and interfere with each other increasing amplitude of the wave to make it easier.
B.the train can not be heard ad easily in the park because of reflection and diffraction. the sound reflects off of the trees in the park and diffract between the tree, this causes the waves to bend too much to be heard.
C.the train can be heard more easily in front of the apartment complex because of diffraction and refraction. the sound waves diffract between the other buildings aiming them towards the apartment complex and then the sound refracts through the apartment complex which makes it more difficult to hear in the park.
D.the train can not be heard as easily in the park because of interference and reflection. the other buildings in front of the park cause interference of the sound waves from the train and the trees in the park cause reflection making it too hard to hear the train.

Rahul sees a flock of birds. He watches as the flying birds land in neat little rows on several power lines. Which change of state does the motion of the birds most closely model?

melting
vaporization
deposition
sublimation

Answers

Answer:

C.) Deposition.

Explanation:

I just took the unit test

The change of state that Rahul sees and models the motion (movement) of the birds is called deposition.

What is deposition?

In physics, deposition can be defined as a transition phase from a gaseous state to a solid without the need to pass to a liquid state.

The physical phenomena of deposition are relatively common in nature and they include many natural processes.

In conclusion, the change of state that Rahul sees and models the motion (movement) of the birds is called deposition.
