What is the difference between a sonic boom and a shock wave?
WINSTONCH [101]

Answer:

When a sound source moves faster than the speed of sound, a shock wave is produced as the sound waves interfere. A sonic boom is the intense sound that occurs as the shock wave moves along the ground.

More importantly, all of the energy gets concentrated into a very small distance this is called a shock wave. In this case, the observer does not hear the approaching source at all until the shock wave hits with all of the energy in the wave. For sound waves, this can cause a very loud noise, called a sonic boom.

Sonic booms produced by aircraft flying supersonic at altitudes of less than 100 feet, creating between 20 and 144 pounds overpressure, have been experienced by humans without injury. Damage to eardrums can be expected when overpres- sures reach 720 pounds

Give at least two examples where people commonly use temperature to control reaction rates.
wariber [46]
The examples may be;
making yogurt; If you heat beyond 130F you kill the cultures. The higher the temperature up until that point the faster it cultures until you close in on killer temperature.
Mixing 2 part epoxy; Keep it cool and the reaction time is delayed. On the other hand, heat it up and epoxy reacts quicker. In the winter time and close to 35 Degrees, the reaction time for cement to harden can take 400% more time to set.

ExtremeBDS [4]
<h3><u>Answer;</u></h3>

C) atoms are more stable when they combine with other atoms

<h3><u>Explanation</u>;</h3>
  • Atoms are the smallest particles of an element that can take part in a chemical reaction.
  • <em><u>Atoms seldom exist as independent particles in nature. Nearly all substances are made up of combinations of atoms that are held together by chemical bonds, which are forces of attractions between the nuclei and valence electrons of different atoms that join the atoms together.</u></em>

A. momentum = mass x velocity
b. kinetic energy = 1/2 x mass x velocity^2
Although total momentum is conserved, total kinetic energy is not necessarily equal. It’s because Jay acted a force on the skateboard and increased the energy of the system.

A compound is made up of two or more of what?
jolli1 [7]
A compound is made up of two or more of atoms that are bonded together with each other via a chemical bonding. It is possible to break the compounds into separate smaller components by the process of chemical reaction. One very simple example of compound is water as it is made of two atoms of hydrogen and one atom of oxygen. Whenever atoms are joined together to create a compound, the atoms definitely loose their individual atomic properties. Other very commonly found compound is carbon dioxide. It is made up of one atom of carbon and two atoms of oxygen.
