The war affected the growth of the federal government in three different major areas: public finance, military spending, and social welfare programs. Until World War II the individual income tax was a minor part of the federal government receipts (affecting no more than 3 percent of the population). However with the introduction of the employee withholding tax in 1943, for the first time a large percentage of the population was subject to the income tax.
Earth's axial tilt (obliquity) is currently about 23.4Â°. Earth's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the celestial equator on the celestial sphere. It is denoted by the Greek letter Îµ. Earth currently has an axial tilt of about 23.4Â°.
Axial tilt of Earth is 23.439281Â° In astronomy, axial tilt is the angle between a planet's rotational axis at its north pole and a line perpendicular to the orbital plane of the planet. It is also called axial inclination or obliquity. The axial tilt of Earth is the cause of seasons like summer and winter on Earth. Axial tilt of bodies in the Solar System To understand axial tilt, we employ the right-hand rule.
