Question

The value of g is ________ everywhere on the surface of the earth. The reason is that the surface of the earth is _______ spherical. due to its rotation, the earth bulges at the ______ and is flatter at the _______ its radius is _______ at the equator and ______ at the poles


Options:
(same, not same, equator,poles, largest, smallest, exactly, not exactly)​

Answer 1

Answer:

The value of g is 9.8 m/s^2 everywhere on earth. The reason is that the surface of earth is roughly spherical. Due to its rotation, the earth bulges at the equator and flatters at the poles, its radius is bulge at the equator and flat at the poles.

Answer 2

Answer:

1) 6.67 × 10^-11

2) oblate spheroid

3) equator

4) poles

5) 6,378 kilometres

6) 6357 kilometres

Explanation:

Since the Earth is flattened at the poles and bulges at the Equator, geodesy represents the figure of the Earth as an oblate spheroid. The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.
