Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
$Assertion$ $(A)$ : The angular speed of the moon in its orbit about the earth is more than the angular speed of the earth in its orbit about the sun.
$Reason$ $(R)$: The moon takes less time to move around the earth than the time taken by the earth to move around the sun.
In the light of the above statements, choose the most appropriate answer from the options given below:
$(A)$ સાચું છે પણ $(R)$એ સાચું નથી.
Both $(A)$ and $(R)$ are correct and $(R)$ is the correct explanation of $(\mathrm{A})$
Both $(A)$ and $(R)$ are correct but $(R)$ is not the correct explanation of $(A)$
$(A)$ is not correct but $(R)$ is correct
The maximum and minimum distances of a comet from the sun are $8 \times {10^{12}}\,m$ and $1.6 \times {10^{12}}\,m$. If its velocity when nearest to the sun is $60\, m/s$, what will be its velocity in $m/s$ when it is farthest
The rotation period of an earth satellite close to the surface of the earth is $83$ minutes. The time period of another earth satellite in an orbit at a distance of three earth radii from its surface will be .......... $\min$
A planet has orbital radius twice as the earth's orbital radius then the time period of planet is .......... $years$
Two heavenly bodies ${S_1}$ and ${S_2}$, not far off from each other are seen to revolve in orbits
A comet orbits the sun in a highly elliptical orbit. Does the comet have a constant $(a)$ linear speed, $(b)$ angular speed, $(c)$ angular momentum, $(d)$ kinetic energy, $(e)$ potential energy, $(f)$ total energy throughout its orbit? Neglect any mass loss of the comet when it comes very close to the Sun.
