Weight on equator is less. Because of centrifugal force. Net accn on equator is
a = g- Rw^2
while on poles it is exact g
hence
Wpole / Weq = g / (g-Rw^2)
= 9.83 / (9.83 - 6400000 x (7.3x10^-5)^2)
= 1.0035

Considering the rotation of the Earth only, compare your apparent weight on the North Pole and on the Equator.
How much difference is there between your apparent weight when standing on flat ground at the equator v.s. at the south pole v.s. at 60 degree latitude? Assume Earth's radius is 6,380 km. What period of rotation for Earth would make you feel weightless at the equator?
2. The rotation of the earth might have an effect on g measured on the Earth. Let's imagine standing on a scale at a latitude on the Earth. Taking the rotation of the Earth into account, we want to evaluate the value of "g" that a scale would read that would be measured as the normal force from the scale (the apparent weight), to be m'g'. a. For a person standing at the north pole: i. Draw your free body...
1) a. Resolve the apparent dilemma. The north pole of a compass is attracted to the north pole of the earth, yet like poles repel. Why? b. Although we cannot see a magnetic field, how can you detect its presence?
Toward which magnetic pole of Earth is the north pole of a compass needle attracted? a. The north pole of a compass needle is attracted to the north magnetic pole of Earth, which is located near the geographic north pole of Earth. b. The north pole of a compass needle is attracted to the south magnetic pole of Earth, which is located near the geographic north pole of Earth. c. The north pole of a compass needle is attracted to...
3. Suppose the Earth is rotated so that its north pole goes to 20° north, 10° west in the original longitude and latitude system and that the 25° west meridian points due south (in the original system). (a) What are the Euler angles describing this rotation? (b) Find the transformation matrix S describing the rotation.
The magnetic field of Earth resembles the field of a bar magnet. The north pole of a compass needle, used for navigation, generally points toward the geographic north pole. Which magnetic pole of the Earth is the compass needle pointing toward?
Earth's atmospheric magnetic flux density is 7.0 mT near the north pole. Near the equator, a power density of 4 kW/m^2 exists from sunlight. A) Determine values for electric and magnetic field strengths due to solar electromagnetic radiation and magnetic flux density of solar EM radiation. B) Compare magnetic flux density of Earth and solar radiation.
The radius of the Earth is 6370. km. (a) Calculate the linear speed at which a point on the Earth's surface at the Equator is moving because of the Earth's rotation. (b) Calculate the linear speed of a point on the Earth's surface in Houston (Latitude = 29.8 degrees North) due to the Earth's rotation and compare with the result at the Equator.
If the Earth were a bar magnet, its magnetic north pole would be located near the geographic North Pole and its magnetic south pole would be located near the geographic South Pole. True False
