Hi, you did not enter the text about the Suarez family, which makes it impossible for this question to be answered accurately. However, from the context of your question, it is possible to see that you want to know two positive and negative points that the Suarez family would observe when starting a planting of organic agriculture.

Among the negative points, we can say that organic agriculture has a high cost, as the techniques used in it require a greater number of resources, which can make not only the service more expensive, but also the product. A second negative point is that the techniques used in organic agriculture are more difficult than the techniques used in conventional agriculture, since all management of organic crops must be carried out without the application of chemical products.

Among the positive points, we can say that the growing number of consumers of organic products can increase the profit that the family will have from the sale of these products. In addition, the family will have healthier, less polluted and more productive land.

A glass optical fiber is used to transport a light ray across a long distance. The fiber has an index of refraction of 1.510 and
Svetradugi [14.3K]

The answer is 73.13°.

According to snell's law,

n1sinθi = n2sinθr

n1/n2 = sinθr/sinθi

The critical angle is the angle of incidence at the denser medium when the angle of incidence at the less dense medium is 90°

This means i=C and r = 90°

The Snell's law formula will become

n1/n2 = sinC/sin90°

n2/n1 = 1/sinC

Where n1 is the refractive index of the less dense medium = 1.473

n2 is the refractive index of the denser medium = 1.540

Substituting the values in the formula,

1.540/1.473 = 1/sinC

1.045 = 1/sinC

SinC = 1/1.045

SinC = 0.957

C = sin^-1(0.957)

C = 73.13°

The refractive index of glass is 1.5. It way that the velocity of mild in glass is 1.5 times slower than the rate of mild in a vacuum, the speed of light in glass isn't always unbiased of the shade of mild.

Refractive index is likewise the same as the velocity of light c of a given wavelength in an empty area divided with the aid of its speed v in a substance or n = c/v.

The index of refraction of fabric is a ratio that compares the velocity of light in a vacuum ( c=3.00x108ms ) to the velocity of mild in that precise medium. Because the index of refraction increases, the amount that the material bends the mild increases.

A 1 kg ball is loaded into a spring gun with a spring constant of 105 N/m. If the spring iscompressed by 0.1 m and the ball is s
Rainbow [258]

Answer:

H = 5.35 cm

Explanation:

As per energy conservation we know that energy stored in the spring is converted into gravitational potential energy when it is reached at the top

now we have

\frac{1}{2}kx^2 = mgh

here we know that

m = 1 kg

k = 105 N/m

x = 0.1 m

now plug in all data in it

\frac{1}{2}(105)(0.1^2) = 1(9.81)(H)

now solving for height H we have

H = 0.0535 m

H = 5.35 cm

3. When does the iron core in an electromagnet become magnetic?​
rosijanka [135]

Answer: When electricity flows through it.

Explanation:

The electromagnet exhibits magnetic properties only as soon as current flows through the nucleus. Namely, the electric current in the space around the electrical conductor through which it passes creates a magnetic field. Unlike a permanent magnet, which has a permanent property of magnetism, the electromagnet is a temporary magnet because the magnetic field also disappears when the current ceases.

<span>Velocity of Electron V1 = 1.50 Ă—10^6 m/s Velocity of Electron V2 = 9.00 Ă— 10^6 m/s We know the mass of electron m = 9.11 x 10^-31 Charge of the electron q = 1.60 x 10^-19 Calculating the potential energy at the two stages, K1 = 0.5 x m V1^2 = 0.5 x 9.11 x 10^-31 x (1.50 Ă—10^6)^2 = 10.24 x 10^-19 K2 = 0.5 x m V2^2 = 0.5 x 9.11 x 10^-31 x (9.00 Ă—10^6)^2 = 368.95 x 10^-19 Change in Potential energy delta K= K2 - K1 = 358.71 x 10^-19 As we know for total energy conservation total change in energy is 0 so q x delta V + delta K = 0 delta V = - delta K / q = 358.71 x 10^-19 / 1.60 x 10^-19 = 224.19V Potential difference for the electron to pass = 224.19V</span>
