Which statements accurately describe Earth’s magnetic field? Check all that apply. The magnetic field lines flow from Earth’s ge
ographic South Pole to Earth’s geographic North Pole. The magnetic field is created by magnetic rocks on the surface. The magnetic poles line up exactly with Earth’s geographic poles. The magnetic field is generated in Earth’s core. The magnetic field is similar to the magnetic field of a bar magnet.
<span>The initial velocity of the bike was 1.67 (vf)m/s. This is found by evaluating 7.5/4.5 which yields the velocity per unit of time which is equivalent to initial velocity.</span>
Atomic Number = amount of protons. Atomic mass = protons (7) and neutrons (8)
Electrons will be the protons - any charge the isotope has. For example, a +2 charge would make the electrons 7- (+2) = 5. A -2 charge would be electrons 7 - (-2) = 9
