Answer: Gas-liquid

Explanation:

Seltzer water is also called “sparkling water” or “carbonated water,” and it refers to the water which has been infused with carbon dioxide gas, which then causes it to bubble.

The type of solution that seltzer water is "gas liquid". Here, the solution is liquid while the solute is gas.

Answer:

1.17

Explanation:

Given that,

The refractive index of ice wrt air = 1.31

The refractive index of rock salt wrt air = 1.54

We need to find the refractive index of rock salt with respect to ice.

We know that,

refractive index = (speed of light in air or vaccum)/( speed of light in that medium)

So,

The speed of light in ice = c/(1.31)

The speed of light in rock salt = c/(1.54)

So, the refractive index of rock salt with respect to ice​ is :

[tex]\mu=\dfrac{1.54}{1.31}\\\\=1.17[/tex]

So, the required refractive index of rock salt wrt ice is 1.17.

Answer:

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

Answer:

The spring constant is 171.43 N/m.

Explanation:

compression in spring, x = 0.07 m

force, F = 12 N

Let the spring constant is K.

Use the formula of the restoring force of the spring

F = K x

12 = K (0.07)

K = 171.43 N/m  

Answer: False

Growing different crops in different seasons in the same field will deplete the soil of nutrients. False. Growing different crops In the same field actually help to improve the fertility of the field.

Answer:

DONT KNOW SORRY XD

Explanation:

BEC I AM BRAINLESS USING BRAINLY

Answer:

Ok, so at point 20 on the x axis you put 12 on the y-axis, then draw a line from 0, 0 to that point, this demonstrates the acceleration to 12 m/s.

Next, calculate the time he cycled for if he suckled the distance of 4800m :

4800/12 = 400 s

Put a dot at 400, 12. The time changed but the speed remained constant, line is horizontal.

For the last one, he had to decelerate at an equal speed. Since there is 100 s left of the journey at that stage, You need to draw a straight line from the previous point to 500, 0. So at time 500 he was not accelerating at all, he came to rest.

Answer:

Workdone = 19600 Nm

Explanation:

Given the following data;

Mass = 40 kg

Distance = 50 meters

We know that acceleration due to gravity is equal to 9.8 m/s².

To find the work done;

First of all, we would determine the force being exerted by the construction worker.

Force = mass * acceleration due to gravity

Force = 40 * 9.8

Force = 392 Newton

Next, we would determine the work done;

Workdone is given by the formula;

[tex] Workdone = force * distance[/tex]

[tex] Workdone = 392 * 50 [/tex]

Workdone = 19600 Nm

Answer:

Laser light however contains only one wavelength. This property makes lasers monochromatic, meaning of one color. Another property of lasers is that all the wavelengths are in phase, meaning they wave together. This property is called coherency. Laser light travels in the same direction, parallel to one another.

Answer:

Explanation:

This is a classic Law of Momentum Conservation problem. For us the equation will look like this:

[tex][(m_yv_y+m_bv_b)]_b=[(m_y+m_b)v_{both}]_a[/tex] Filling in with our given info:

[tex][(70.0)(0)+(.40)(10.0)]_b=[(70.0+.40)v_{both}]_a[/tex] and

4.0 = 70.4v and

v = .06 m/s

Yes

Explanation:

If there were to be a supernova of a star or a planet/meter that was directed at earth, then we would know in advance and make a plan to stop it

Assume R is measured in meters (m) and M in kilograms (kg). Then

R ² / (GM) = [m]² / ([N•m²/kg²] [kg]) = m•kg / N = m•kg / (kg•m/s²) = s²

so t ² is indeed proportional to R ²/(GM).

Answer:

a)  [tex]m_v= 56.16 Kg[/tex]

    [tex]m_l= 14.04 Kg[/tex]

b)  [tex]\mu=1.37\%[/tex]

Explanation:

From the question we are told that:

Volume of tank [tex]V_t=1m^3[/tex]

Temperature of [tex]CO_2=-17^oC[/tex]

Quality of the mixture [tex]Q= 70%[/tex]

Specific Volume constants at [tex]-17^oC:[/tex]

 [tex]v_f = 0.9827*10^{-3} m3/kg[/tex]

 [tex]v_g =1.756*10^{-2} m3/kg.[/tex]

Generally the equation for Specific Volume is mathematically given by

 [tex]v = v_f + x (v_g -v_f)[/tex]

 [tex]v= (0.9827 * 10^{-3} ) + 0.8 * (17.56 * 10^{-3} -0.9827 * 10^{-3})[/tex]

 [tex]v= 0.014244 m3/Kg[/tex]

Generally the equation for Mass is mathematically given by

 [tex]m=\frac{v'}{v}[/tex]

 [tex]m=\frac{1}{0.014244}[/tex]

 [tex]m=70.20 Kg[/tex]

Generally the Mass of saturated Vapor is mathematically given by

 [tex]m_v=0.8 * (70.202)[/tex]

 [tex]m_v= 56.16 Kg[/tex]

Generally the Mass of saturated Liquid is mathematically given by

 [tex]m_l = (70.20 Kg)-(56.16 Kg)[/tex]

 [tex]m_l= 14.04 Kg[/tex]

b)

Generally the equation for Volume is mathematically given by

 [tex]v_l = m_l x v_f[/tex]

 [tex]v_l= (14.04 Kg) (0.9827 x 10{-3} m3/kg)[/tex]

 [tex]v_l= 0.01379 m^3[/tex]

Therefore Percentage of liquid

 [tex]\mu = \frac{v_l}{v} * 100 \%[/tex]

 [tex]\mu= [(0.01379 m^3)/(1 m^3)] *100 \%[/tex]

 [tex]\mu=1.37\%[/tex]

The weight of the satellite at a distance of one Earth radius above the surface of Earth is 40 N.

The given parameters:

The gravitational force on the satellite is calculated by applying Newton's law of universal gravitation is calculated as;

[tex]F = \frac{Gm_1m_2}{R^2} \\\\F_1 R_1^2 = F_2R_2^2\\\\F_2 = \frac{F_1 R_1^2 }{R_2^2} \\\\F_2 =\frac{200 \times R_1^2}{(2R_1)^2} \\\\F_2 = \frac{200 \times R_1^2 }{4R_1} \\\\F_2 = 40 \ N[/tex]

Thus, the weight of the satellite at a distance of one Earth radius above the surface of Earth is 40 N.

Answer:

The acceleration (a) is the gravitational constant (g), so 9.81 or 9.8 or 10 (9.81 in this case)

Final velocity:

Vf = vi (0 in this situation ) + gt

Vf = 9.8 * 260 (time in seconds)

Vf = 2548

(I am not sure why here it is 4.6, but since that is the only option after we answer the other two questions, it is.)

h = 1/2gt^2

h = 331240 meter (a lot) (I converted minutes to second by multiplying 4 my 60 + the other 20 sec) (The answer is a bit different because I used 9.8 as gravitational constant and they used 9.81)

Answer:

Explanation:

If the passage of the waves is one crest every 2.5 seconds, then that is the frequency of the wave, f.

The distance between the 2 crests (or troughs) is the wavelength, λ.

We want the velocity of this wave. The equation that relates these 3 things is

[tex]f=\frac{v}{\lambda}[/tex] and filling in:

[tex]2.5=\frac{v}{2.0}[/tex] so

v = 2.5(2.0) and
