No, the area swept out per unit time by Earth moving around the Sun is not equal to the area swept out per unit time by Mars moving around the Sun. This is because each planet has a unique orbital period and distance from the Sun, resulting in different rates of angular motion.
When the product of frequency and time period is equal to 1, it indicates that the oscillation completes one full cycle in one second, which is the definition of the unit hertz (Hz) for frequency.
The SI unit for time is the second.
Probably the most important difference is the fact that 'light-year' is a unit of distance, whereas orbital 'period' is a unit of time.One light-year is defined as the distance that light ... or electromagnetic radiation of any wavelength ... covers in one year of propagation through vacuum, equal to roughly 5,878,700,000,000 miles.The orbital period of earth, or the time that elapses during one complete revolution of the earth around the sun, is roughly 365.25 days, a duration commonly referred to as the 'year'.
The unit of a period is the second, because it is a time, and the SI unit for time is the second. Of course, you can also use other time units, such as microseconds, years, etc.
An era is a time period of indeterminate length, or, geologically speaking, a unit of time, smaller than aeons and greater than periods.
The SI unit for period is seconds and the symbol is t (because the period is a time measurement, it is expressed in the SI unit seconds)
Yes, a newton is a unit of weight equal to 0.1kg / 0.2248 lbs. on earth.
Yes, a year is a unit of time. The period of one year is 365 days.
a fortnight is a unit of time, equal to 14 days.
An astronomical unit (au) is a unit of length equal to the distance from the Earth to the SUun. It is approximately 150 million kilometers (93 million miles).
