the third once because if you multiply them you get 2800 and 14 days is the same as 2 weeks
C) The gravitational forces of people is so small it is overshadowed by that of Earth.
No atoms create electricity and radiation
If light is traveling through a medium (i.e. air), the color of light depends on the wavelength.
The following are wavelength intervals of colors on the visible light spectrum. Measured in nanometers (nm).
Red: 700–635 nm
Orange: 635–590 nm
Yellow: 590–560 nm
Green: 560–520 nm
Blue: 490–450 nm
Violet: 450–400 nm
Answer:
D). Field lines circle the Earth from east to west.
Explanation:
A microscopic force or gigantic magnetic field surrounds the Earth which functions as a force field that guards the planet against the radiations released from space. This magnetic field is characterized by the alignment of the North and South poles with the axis of rotation. Thus, the magnetic field lines of the Earth surround or circle of the Earth from East to West. Therefore, <u>option D</u> is the correct answer.
