Kepler's second law (law of areas) is nothing but a statement of
1 Work-energy theory
2 Conservation of linear momentum
3 Conservation of angular momentum
4 Conservation of energy
Explanation:
C Kepler's second law is the consequence of law of conservation of angular momentum. It states that a line between Sun and planet sweeps equal area in equal times. In planetary motion, the momentum, angular momentum and mechanical energy is conserved. Hence, option (c) is correct.

A comet orbits the Sun in a highly elliptical orbit. The quantities that remain constant throughout its orbit are
1 Angular speed and angular momentum
2 Kinetic energy and potential energy
3 Angular momentum and total energy
4 Angular speed and total energy
Explanation:
C When comet orbits the Sun in a highly elliptical orbit then torque excreted by the Sun on the comet is zero. - Total energy of the comet remains constant - Angular speed $(\omega)$ of the comet is not constant. - Angular momentum of the comet is constant. - Linear speed (v) of the comet is not constant.

A planet revolves in an elliptical orbit around the sun. The semi- major and semi- minor axes are $a$ and $b$. Then the square of time period, $T$ is directly proportional to
1 $\mathrm{a}^{3}$
2 $\mathrm{b}^{3}$
3 $\left(\frac{a+b}{2}\right)^{3}$
4 $\left(\frac{a-b}{2}\right)^{3}$
Explanation:
A Given, semi major axes $=\mathrm{a}$ semi minor axes $=b$ According to Kepler's third law, Square of time period $\mathrm{T}$ is directly proportional to cube of semi-major axis i.e. $\mathrm{T}^{2} \propto \mathrm{a}^{3}$.

A planet is moving around the sun in an elliptic orbit. Its speed
1 is the same at all points of the orbit
2 is maximum when it is farthest from the sun
3 is maximum when it is nearest to the sun
4 is maximum at the two points in which the orbit is intersected by the line which passes through the focus of the orbit and which is perpendicular to its major axis
Explanation:
C A planet is moving around the sun in an elliptical orbit. Its speed is maximum when it is nearest to the sun. Kepler's second law helps to establish that when a planet is closer to the Sun, it travels faster.
