Answer:

To communicate with each other

Explanation:

Cows use sound (mooing) to communicate with each other and their environment. Cows are herd animals and have complex social structures. Mooing is one way that they interact and how they express their emotions

Tom lost money on his peach crops because they kept freezing in the winter. How could Tom most likely solve the problem of his p
vova2212 [387]

Answer:

B. He could breed his peach plants with peach plants that can survive the frost.

Explanation:

Tom can best solve his problem by breeding his peach plants with the ones that can survive the frost.

  • This is known cross breeding
  • The goal of cross breeding is to produce offspring that contains the traits of both of the parents or an improved hybrid.
  • If Tom can cross breed the failing peaches with the successful winter resistant ones, he can ensure better production.
  • The new hybrid will therefore will be genetically superior and adapted to the prevailing environmental changes.

Among the elements of the main group, the general trend in the first ionization energy moving across a period is not followed be
Radda [10]
<span>The Ionization energy decreases because the full s orbital shields the electron entering the p orbital. This is known as "shielding", When each new electron experiences attraction from the nucleus and repulsion forces from the S orbitals, the net force on outer shell electrons is significantly smaller. Therefore, ionization energy decreases during these groups.</span>

<h3>How Nuclear Fusion Reactors Work?</h3>

­W­hen hydrogen atoms fuse, the nuclei must come together. However, the protons in each nucleus will tend to repel each other because they have the same charge (positive). If you've ever tried to place two magnets together and felt them push apart from each other, you've experienced this principle firsthand.

To achieve fusion­, you need to create special conditions to overcome this tendency. Here are the conditions that make fusion possible:

High temperature gives the hydrogen atoms enough energy to overcome the electrical repulsion between the protons.

  • Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun's core).
  • At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about.
  • The sun achieves these temperatures by its large mass and the force of gravity compressing this mass in the core. We must use energy from microwaves, lasers and ion particles to achieve these temperatures.

High pressure squeezes the hydrogen atoms together. They must be within 1x10-15 meters of each other to fuse.

  • The sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core.
  • We must squeeze hydrogen atoms together by using intense magnetic fields, powerful lasers or ion beams.
