Answer:

When the leftovers are left in the autumn, they have two purposes:

- Preventing erosion; the roots remain in the ground, so they hold it tightly till the next planting of the crops.

- Fertilizing the soil with natural material; the roots will not rot quickly in the colder period of the year, but will start rotting much faster in the spring, thus they will enrich the soil.

Physics help please:Explain the mechanism by which AC (alternating current) through the primary circuit of a transformer produce

Makovka662 [10]

In the transformer we use from faraday's law.in this low when a variable current pass from a loop of wire, make variable flux and when variable flux in a loop make variable current in loop.be careful that current or flux must to be variable.

Si aplicas una fuerza constante (F=constante) a un cuerpo de masa m1, dicho cuerpo se acelerará a1. Nuevamente, si aplicas la mi

Nitella [24]

Debido a que la fuerza es constante, a medida que la masa aumenta, la aceleración disminuye. Por lo tanto, la mayor aceleración sería a1.Utilicé Google traductor, lol. Sin embargo, espero que esto ayude.

Jane and John Doppler effect

UkoKoshka [18]

Answer:

To summarize, Jane's star has a red light and is traveling towards the Earth while John's star has a blue light and is traveling away from the Earth. This is a prime example of the Doppler Effect in motion. The stars look different because they are traveling in different directions.

Ocean waves are traveling to the east at 3.2 m/s with a distance of 19 m between crests. (a) With what frequency do the waves hi

rjkz [21]

Answer:

(a) Frequency will be 0.168 Hz

(b) Frequency will be 0.0789 Hz

Explanation:

(a) We have given velocity of the ocean waves in east direction v = 3.2 m /sec

Distance between the crest $\Delta x=\lambda =19m$

We know that $v=\lambda f$

So $3.2=19\times f$

$f=0.168Hz$

(b)Velocity of the ocean waves in westward direction v = 1.5 m /sec

Distance between the crest $\Delta x=\lambda =19m$

We know that $v=\lambda f$

So $1.5=19\times f$

$f=0.0789Hz$

What is speed of the light

kotykmax [81]

The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second.
