For seismograph A, the lag time is
5 minutes (difference between 6:10 and 6:05)
For seismograph B, the lag time is
15 minutes (difference between 6:25 and 6:10)
Assuming that earthquake waves have a constant velocity during the earthquake, then the seismograph with the shorter lag time is closer to the epicenter. So,
Seismograph is closes to the earthquake's epicenter
Answer:
Vinegar is an aqueous solution of acetic acid and trace chemicals that may include flavorings. Vinegar typically contains 5–8% acetic acid by volume. Usually the acetic acid is produced by the fermentation of ethanol or sugars by acetic acid bacteria. There are many types of vinegar, depending on source materials.
Answer:
Oil is a global issue because it is one of the most used resources for energy, but also one of the biggest polluters.
Explanation:
Oil is a natural resource that falls into the category of fossil fuels. It is a ofssil fuel that has helped the economies around the world to skyrocket and develop exponentially. This has been due to the properties of oil that releases enormous amounts of energy, thus it able to drive the industry forward.
This resource though also has become a huge problem. It is a big polluter, and it is obvious how much its usage has affected the atmosphere and environment in negative manner. Also, it is not unlimited, but eventually the reserves of it will end, so relying on it until that point will be devastating for the whole world. The whole world needs to work together, sooner rather than later, in order to gradually switch to energy sources that will be economically jutifiable but also environmental friendly, as if everything continous as until now the consequences will soon be irreparable and everyone will feel them.
Hey there! I'm happy to help!
Let's see where the word tumultuous is used here:
Magellan named the ocean Pacifico (Pacific) which means peaceful because, compared to the tumultuous strait they had just been through, the ocean was amazingly calm.
We see that they named the ocean the Pacific Ocean because it was very peaceful and calm compared to a tumultuous strait. This shows us that tumultuous is probably the opposite of peaceful. It probably means crazy, hectic, rough, harsh, etc. After going through a crazy thunderstorm, a light sprinkle would seem very peaceful, which is similar to how Magellan probably feels here.
This definition matches best with answer A. rough and uncertain.
Have a wonderful day! :D
