Answer:

Solubility in gasses and liquids increase as pressure increases. This is due to colligative properties. The nitrogen gas levels would increase the farther the diver dives due to the increase of pressure causing the solubility of the nitrogen to increase, thus increasing the amount of it as you go deeper in the ocean.

Explanation:

As they plummet down, the driver would be in more risk. The solubility of gases and liquids increases as pressure increases. This is due to the existence of colligative properties. The nitrogen gas levels grow when the diver descends further into the water due to increased pressure, which causes the nitrogen's solubility to rise, increasing the amount of nitrogen present.

The relative motion of the train next to her is the motion of the other train in her rest frame.

As the other train leaves, it seems to Sunita as if her train is moving backwards

Reason:

The motion of the train Sunita is taking is given by the rate of movement of

objects outside the train from the front side of the train towards the back

side of the train, that way she can tell that the train is moving.

The motion of the other train from the rear side of the train from the rear

side of the train to the front side is a reverse motion to what Sunita

observes when the train is moving forward. Therefore, as the other train

leaves, it seems to Sunita as if her train is moving backwards.

Answer:

around 1436.76 cm^3

Explanation:

v = 4/3(3.14)7^3

v = 4/3(3.14)343

v = 4/3(1077.02)

v = 1436.02666667

round up

v = 1436.027

if you use pi, then the answer would be around 1436.76 cm^3

The equation of the constructor of the geomeric optics allows to find the results for the distance and size of the objects are:

The equation of the constructor of geometric optics describes the position of objects and their images for mirrors and lenses.

       [tex]\frac{1}{f} = \frac{1}{p} + \frac{1}{q}[/tex]  

Where f is the focal length, p and q are the distances to the object and the image, respectively.

They indicate the focal length f = 10 cm, the distance to the image q = 40 cm, that the height s h ’=  4 cm.  In the attachment we see a scheme of the system.

Let's find the distance to the object.

        [tex]\frac{1}{p\frac{x}{y} } = \frac{1}{f} - \frac{1}{q} \\\frac{1}{p} = \frac{1}{10} - \frac{1}{40}\\\frac{1}{p} = 0.075[/tex]

       p = 13.3 cm

The magnification in the ratio of image size to object size.  The image is inverted so its height is negative.

        [tex]m = \frac{h'}{h} = - \frac{q}{p}\\h = - \frac{p}{q} \ h'\\h = - \frac{13.3}{40}\ (-4)[/tex]

        h = 1.33 cm

In conclusion using the equation of the constructor we can find the results for the distance and size of the objects are:

Answer:

for max :

100 feet in 10 secs

for molly :

60 feet in 5 secs = 120 feet in 10 secs

so, molly ran farther in the same time interval i.e. covered 120 feet where as Max covered 100 feet

Explanation:

brainliest plz

Answer:

1 no Max

2 no Molly

Explanation:

because if molly can run 60 feet in 5 second he can run 120 feet in 10 second

The advantage for using 16-inch spacing is that ; ( B ) At a given load, the 16-inch spacing can support a larger span

The spacing along a span in construction engineering is determined by the amount and mass of load the span will either carry or support during and after construction.

A smaller span spacing can support a given load more efficiently than a larger span spacing because when the spacing is smaller it can support a larger span better than a larger span spacing.

Hence we can conclude that the advantage for using 16-inch spacing is that At a given load, the 16-inch spacing can support a larger span.

The conservation of the momentum allows to find the result of how the astronaut can return to the spacecraft is:

The momentum is defined as the product of the mass and the velocity of the body, for isolated systems the momentum  is conserved. If we define the system as consisting of the astronaut and the evo propellant, this system is isolated and the internal forces become zero. Let's find the moment in two moments.

Initial instant. Astronaut and thrust together.

        p₀ = 0

Final moment. The astronaut now the thruster in the opposite direction of the ship.

       [tex]m_f[/tex] = m v + M v '

where m is propellant mass and M the astronaut mass.

As the moment is preserved.

       0 = m v + M v ’

      v ’= [tex]- \frac{m}{M} \ v[/tex]  

We can see that the astronaut's speed is in the opposite direction to the propeller, that is, in the direction of the ship.

The magnitude of the velocity is given by the relationship between the masses.

In conclusion, using the conservation of the momentun we can find the result of how the astronaut can return to the ship is:
