Answer:

A fish that lives near the surface of the ocean most likely has a swim bladder (or body cavity) that is full of oxygen

Explanation:

The swim bladder is the organ present in the majority of bony fishes that provides buoyancy. The swim bladder is a bladder filled with oxygen and found in the in the body of the fish

The function of the swim bladder is to provide adequate ballast or hydrostatic balance to enable a fish to keep to a certain depth in a body of water thereby the fish does not float to the surface or sinks further

The swim bladder is also used as a sound communicating organ.

If there are no dissipative forces acting on the string, than the principle of conservation of energy holds.

When the string is relaxed, it has zero elastic potential energy

If we were strech the she spring, we would increase it's potential energy. After releasing the spring, when it's relaxed again, all potential energy will have been converted into kinetic energy.

Therefore, the elastic potential energy of the stretched spring should be equal to the amount of kinetic energy when it's relaxed

Answer:

Air moves from the areas of higher temperature to areas of lower temperature.

Explanation:

this is because hotter temperatures seek out colder temps.

hope this helped!

When a teacher opens a window on a cold day. the room starts to feel cooler because air moves from the areas of higher temperature to areas of lower temperature.

The transfer of heat between two bodies by currents of moving gas or fluid is known as convective heat transfer. In free convection, air or water rises and is replaced by a cooler parcel of air or water as it moves away from the hot body.

As air moves from the areas of higher temperature to areas of lower temperature, when the teacher opens a window on a cold day, the air in the room moves out side and cold air takes the position inside the room. So, it feels cooler then.

Answer:

[tex]T_2=\frac{T}{2}[/tex]

Explanation:

Given that engine 1 produces twice the power of engine 2.

Let [tex]P_1[/tex] and [tex]P_2[/tex] be the power of engine 1 and engine2.

So, the power of the engine 2,

[tex]P_2 = 2P_1\cdots(i)[/tex]

As, Work = Power x time,

So, the work, W, done by an engine 1:

[tex]W=P_1\timesT\cdots(ii)[/tex]

The work, W, done by an engine 2:

[tex]W_2=P_2\times T_2\cdots(iii)[/tex]

If the work done by both the engines are the same, then

[tex]W_2=W[/tex]

[tex]\Rightarrow P_2\times T_2=P_1\timesT[/tex] [from (ii) nd (iii)]

[tex]\Rightarrow 2P_1\times T_2=P_1\timesT[/tex] [by using (i)]

[tex]\Rightarrow 2 T_2=T \\\\\Rightarrow T_2=\frac{T}{2}[/tex]

Hence, [tex]T_2=\frac{T}{2}.[/tex]

The time taken for engine 2 to do the same amount of work is given by:

Let the power of the 1st engine be P₁

Let the power of the 2nd engine be P₂

From the question given above,

Engine 1 produces twice the power of engine 2.

Thus,

P₁ = 2P₂

P₂ = ½P₁

Work = W

Time (T₁) = T

Power = Work / time

Work = W

Power of engine 1 (P₁) = [tex]\frac{W}{T}\\\\[/tex]

Power of engine 2 (P₂) = ½P₁

Power of engine 2 (P₂) = [tex]\frac{1}{2} (\frac{W}{T}) = \frac{W}{2T}[/tex]

[tex]Power = \frac{Work}{time} \\\\ P_{2} = \frac{W}{T_{2}} \\\\\frac{W}{2T} = \frac{W}{T_{2}} \\\\\frac{1}{2T} = \frac{1}{T_{2}}\\\\[/tex]

Therefore, the time taken for engine 2 to do the same amount of work is: T₂ = 2T

Though the question does not ask for anything, I'll assume you need to calculate the speed of the lift.

Answer:

The lift travels at 1.4 m/s

Explanation:

Kinetic Energy

Is the type of energy of an object due to its state of motion. It's proportional to the square of the speed and the mass.

The equation for the kinetic energy is:

[tex]\displaystyle K=\frac{1}{2}mv^2[/tex]

Where:

m = mass of the object

v = speed at which the object moves

The kinetic energy is usually expressed in Joules (J)

If we already know the value of the kinetic energy, we can find the speed by solving for v:

[tex]\displaystyle v=\sqrt{\frac{2K}{m}}[/tex]

The lift has a mass of m=4200 Kg and has a kinetic energy of K=4116 J, thus it's moving at a speed of:

[tex]\displaystyle v=\sqrt{\frac{2*4116}{4200}}[/tex]

[tex]\displaystyle v=\sqrt{1.96}[/tex]

v = 1.4 m/s

The lift travels at 1.4 m/s

Answer:

The value is  [tex]V_2 = 1.9396 *10^{-5} \  m^3 [/tex]

Explanation:

From the question we are told that

   The depth at which the bubble is released is  [tex]h = 115 \ m[/tex]

    The volume of the air bubble is  [tex]V = 1.60 cm^3 = 1.60 *10^{-6} \ m^3[/tex]

Generally from the ideal gas law

     [tex]PV = nRT[/tex]

Given that  n , R , T are constant we have that

    [tex]PV = constant[/tex]

So    

    [tex]P_1 V_1=P_2 V_2[/tex]

Here [tex]P_1[/tex] is the pressure of the bubble at the depth where it is released which i mathematically represented as

      [tex]P_1 = P_a + P[/tex]

Here [tex]P_a[/tex]  is the atmospheric pressure with value  [tex]P_a = 101325 \ Pa[/tex]

and   [tex]P[/tex] is the pressure due to the depth which is mathematically represented as

       [tex]P = \rho * g * h[/tex]

So

       [tex]P = 1000 * 9.8*115[/tex]

=>    [tex]P = 1127000\ Pa[/tex]

Here  [tex]\rho[/tex] is the density of pure water with value  [tex]\rho = 1000 \ kg/m^3[/tex]

        [tex]g = 9.8 \ m/s^2[/tex]

        [tex]V_1[/tex] is the volume of the bubble at the depth where it is released

        [tex]P_2[/tex] is the pressure of the bubble at the surface which is equivalent to the atmospheric temperature

        [tex]V_2[/tex] is the volume of the bubble at the surface

So

      [tex]V_2 = \frac{ P_1 * V_1}{ P_2}[/tex]

=>    [tex]V_2 = \frac{(Pa+ P) * V_1}{P_a}[/tex]

=>    [tex]V_2 = \frac{101325 + 1127000   * (1.60 *10^{-6})}{ 101325 }[/tex]

=>    [tex]V_2 = 1.9396 *10^{-5} \  m^3 [/tex]

The complete question is;

The gravitational force between two objects is ______ proportional to the products of the masses and _______ proportional to the square of the distance between them.

Answer:

First dash is directly

Second dash is inversely

Explanation:

From Newton's law of gravitation the gravitational force is given by the equation;

F = GMm/r²

Where:

F is gravitational force

M and m are two masses representing the two objects

r is the distance between them

G = universal gravitational constant

Thus, if we are to write it in proportion format, we will have;

F ∝ Mm/r²

From this proportion relationship, we can see that the Gravitational force is directly proportional to the products of the two masses and inversely proportional to the square of the distance between them.

Answer:

This is FRESH AIR. I'm Terry Gross. Loud concerts, power tools, construction work - they're affecting people's hearing. Hearing loss isn't just a problem for older people. In a few minutes, we're going to talk about some of the new high-tech ways of dealing with it. That's the subject of the latest New Yorker article by my guest, David Owen, who is a staff writer for the magazine. He's also a contributing editor at Golf Digest, which is how he got to play golf with Donald Trump. We'll talk about that, too.

But we're going to start with the subject of Owen's new book, "Where The Water Goes," about the Colorado River. The river and its tributaries supply water to over 36 million people in seven states - Colorado, Wyoming, Utah, New Mexico, Nevada, Arizona and California - and irrigates close to 6 million acres of farmland. Owen writes about the engineering feats that make all that possible and the legal and environmental battles surrounding the river. The Colorado River is so overtaxed that by the time it reaches the U.S.-Mexico border it's dry.

David Owen, welcome to FRESH AIR. So can you give us a kind of overview sense of the manmade things that have been done to control and disseminate water from the Colorado through the West?

DAVID OWEN: When you look at the Colorado River, it's not a big river. It's done these amazing things. It carved the Grand Canyon. But it's not - it's not broad. It's not like the Mississippi. The Mississippi is 1,000 miles longer, and the entire annual flow of the Colorado River flows down the Mississippi every couple of weeks. And yet in the western United States, it's incredibly important, in seven states. It supplies water to something like 26 million people. It irrigates 6 million acres of agriculture. And most of those 6 million acres are land that the river itself deposited, silt from, you know, what's missing from the Grand Canyon. It spread out across Arizona and California.

So there's this enormous network of canals and irrigation ditches and tunnels that draw water from that river and take it in some cases hundreds of miles away, you know, 300 miles to the west to Los Angeles, you know, 300 miles to the east to Phoenix and Tucson, hundreds of miles across deserts into reservoirs and canal systems. And it's governed by its own - its own laws that determine who gets to pull that water and use it and what they get to use it for.

GROSS: The plan for dividing the water among the seven river states - Wyoming, Colorado, Utah, New Mexico, Arizona, Nevada, California - that was written up in 1922. You seem to think it's a pretty bad agreement. What makes it so bad?

OWEN: Everybody thinks it's both a bad agreement and a good agreement. It's bad because it divided up the river at a time when people thought the river contained a lot more water than it actually does. It's one of these great sort of ironies of history that in the 19 - the 1920s were some of the wettest years in that part of the country since the 1400s. So the river at that time was carrying more water than ever. And so when the states divided up the river, they were dividing up - actually water that didn't exist. On the other side, the good side is that, well, it's almost a century later and that compact, the agreement among those states, still exists.

GROSS: So how has the world and how has the population in the West changed since 1922 in ways that might make that agreement kind of out-of-date?

OWEN: Well, in lots of ways. There are many more people than anybody imagined in 1922. Some of the biggest, fastest-growing cities in the country are cities that depend on water from that river. Some of the most productive agricultural land draws water from that river. You know, for a long time the fact that they had divided up water that wasn't there didn't make any difference because nobody figured out how to use up all the water anyway. But now we've gotten much better at it and we use it up. So we stretch it farther than people did in those days.
