1. "kepler y sus trabajos". Responde a las preguntas siguientes: a) (1,0) Nombra y explica las leyes de Kepler. b) \( (1,5) \) Un satélite artificial dista del centro de la Tierra \( 6,8 \cdot 10^{3} \mathrm{~km} \) en el perigeo y \( 7,2 \cdot 10^{3} \mathrm{~km} \) en el apogeo. Si la velocidad máxima del satélite es \( 3,5 \cdot 10^{3} \mathrm{~m} / \mathrm{s} \), calcula su velocidad areolar y \( \vec{L} \) para giro antihorario.

QUESTION 7 (Start on a new page.) 7.1 Reflection of light (and other forms of electromagnetic radiation) occurs when the waves meet a surface or other boundary that does not absorb the energy of the radiation and reflects the waves off the surface. Draw a fully labelled ray diagram to illustrate reflection.

QUESTION 6 (Start on a new page.) It has been established that the planet Omega has a moon and that the moon of Omega orbits the planet at a height, above the surface of Omega, which is equal to twice the radius of Omega. The mass of planet Omega is \( 3 \times 10^{15} \mathrm{~kg} \) and the mass of its moon is \( 1.5 \times 10^{13} \mathrm{~kg} \). The radius of the planet Omega is \( 8.5 \times 10^{6} \mathrm{~m} \) and the radius of its moon is \( 2.5 \times 10^{5} \mathrm{~m} \). 6.1 Determine the distance between the centre of the planet Omega and the centre of its moon.

An object of mars 5.0 kg moves around a aincle of radius 6.0 m coith a constant speeds of 10 . om/s. Calc-te 1 . angular velocity Centripetal force on the body

OPEN-ENDED QUESTION What determines how much a wave diffracts when it meets and obstacle or opening?
