What is the difference between a synodic period and a sidereal period? What is the difference between a synodic month and a sidereal month?

In Arrhenius, we are limited to cases in which water is the solvent (this is assumed by Arrhenius). An acid will dissolve in water to produce $H^+$ ions, while a...

The orbital period can be calculated using Kepler's 3rd law, which states that the square of the orbital period is proportional to the cube of the average distance from ....

Observing their position on a star map and wait till they return to that position again. and counting days elapsed..

The distance between perihelion and aphelion is twice the semi major axis distance. So the semi major axis $a=5 AU$. Kepler's third law relates the period $T$ to the semi-major...

As earth moves around Sun for solar day earth have moved 1 degree around Sun in 24 hours.So we have to add 4 minutes to get this additional movement..THat is...

The sidereal year is the time it takes to return to the same place with respect to the fixed stars. The mean sidereal year is $Y_s=365.256363$ days. During this time...

Earth's orbital period is called a year. Rotation period is called a day. SOLar day is 24 hours but Earth is moving around Sun one degree every day..

We have an equinox instant, once in six months, nearly. The two are Vernal Equinox and Autumnal Equinox. Vernal Equinox year is March 21 to March 20, nearly. This is...

Depending on how a particle's kinetic energy compares with its rest mass energy, particles are classified into: Non-relativistic: $E_k \lt\lt E_0$, Relativistic : $E_k \approx E_0$, Super-relativistic:...

One more proton, one more positively charged nuclear particle, than the element to ITS left (as we face the Table). And since atoms are neutral, it must also have an...
