Answer: Option (a) is the correct answer.
Explanation:
Global Positioning Systems (GPS) is a system which uses a network of satellites to construct maps. So, that it would be easy to trace location of a person, or to reach over a certain place.
It helps an individual by showing the route of destination wherever he/she wants to reach along with the total time to reach over the place.
Thus, GPS can determine the elevation of a given area and also it can determine latitude and longitude of a given area. As each GPS satellite broadcasts with a high power, narrow bandwidth, down link signal which can be received by our small hand held receiver antenna called mobile phone.
A GPS cannot determine the composition of soil on mountain ranges.
Thus, we can conclude that out of the given options, GPS can determine the composition of soil on mountain ranges is not true about the Global Positioning Systems (GPS).
Answer:
10.0 N West
Explanation:
Imagine East is positive and West is negative. Essentially now we have 2 forces pulling opposite each other on the same plane, so we can add them up.
F1=20N
F2=-30N
F1+F2=Net Force
20+(-30)=-10
Therefore the Net Force is 10N West.
The answer would be to research the need. This should have been done before the project began.
True
Explanation:
A base is a substance that is often used as the chemical opposite of an acid.
Both behaves in opposite way to one another.
They can be said to complementary or conjugate chemicals.
- According to Bronsted-Lowry theory, an acid is a proton donor and a base is a proton acceptor.
- The lewis theory states that an acid is an electron pair acceptor while a base is an electron pair donor.
- Acids turn blue litmus paper red and bases turns red litmus paper blue.
