subtract 8 from both sides leaving
combine -2x+-8x =-10x
divide both sides by ten
Answer: The potential energy in the system is greatest at X
Explanation: Potential energy is how much energy an object can have. Gravity has an effect on potential energy, the higher something is, the more potential energy it has. For example, if you hold a book above your head, that book has potential energy. When you drop the book, it has kinetic energy. Therefore, since point X is the highest point, the ball has the greatest potential energy there.
Answer:
Fertilizer: The ash from the volcanoes can act as extra nutrients for plants. The chemicals in the ash can make the soil richer which is beneficial for many plants.
Tourism: Volcanoes can attract people from all over the world. This can cause people to pay in order to visit. This can be beneficial to people who like in the area, since they can make money off of the tourist
Research: Volcanoes can allow humans to better understand the earth. They can also learn the patterns of the volcano's eruptions or the seismic activity leading up to the eruption.
Entertainment: Volcanoes can be used as entertainment. For example, people go on hikes or study the environment. This can lead to discoveries also.
The plane would reach a latitude of 38°N.
When it comes to lines of latitude, the Equator is 0°. Locations south of the equator increase from 0° as you go further South and those north increase from 0° as you go North.
If you therefore go from 17°S northward, the degrees of latitude will keep decreasing till you get to 0° and then start increasing as you go North.
The new location in this case will therefore be North:
= 55 - 17
= 38 °N
In conclusion, the plane will keep going North until it passes the Equator at 0° then it will keep going North till it gets to 38°N.
