Answer:
Topographic maps generally shows Natural features such as Rivers and Lakes.
sometimes they also show some features made by humans like brodges, elevations etc.
Answer:
when high-energy particles from the sun are trapped by earth's magnetic field
Explanation:
it is produced by a "depression" in the Earth's magnetic field in that area, caused by the fact that the center of the Earth's magnetic field is deviated from its geographic center by 450 km. Such an anomaly is thought by some to be a side effect of a Geomagnetic Reversal. These radiation belts originate from the Earth's intense magnetic field that is the product of their rotation. That field traps charged particles (plasma) from the Sun (solar wind), as well as charged particles that are generated by interaction of the Earth's atmosphere with cosmic radiation and high-energy solar radiation.
To calculate this, the first step is to determine the number of protons in each atom of the ion. You can use their atomic number to find the number of protons. If the number protons and electrons are equal there is no charge, so the next step is to determine how many electrons to add or remove to the number of protons.
Answer:
Error percentage = 1.326% , 1.35% , 5.37%
density = mass / volume
For first sample:
density = 37.22/11.5 = 3.2365 g/ml
then percentage error = 100% - (3.2365/3.28 ) * 100 = 1.326%
For second sample:
density = 37.21/11.5 = 3.2356 g/ml
then percentage error = 100% - ( 3.2356 / 3.28 ) *100 = 1.35%
For third sample:
density = 37.25/12 = 3.104 g/ml
then percentage error = 100% - ( 3.104 / 3.28 ) *100 = 5.37%
