Чему равна сила тяготения между двумя одинаковыми яблоками радиусом 5 сМ и массой 350 г каждый, если они лежат вплотную друг к другу? Запиши ответ числом, умножив его на \( 10^{10} \) и округлив до целых.

5. Qué energía potencial posee un objeto con una masa de 6 kg a. A 4 m del suelo. b. A 6 m del suelo. 6. ¿A qué altura debería situarse una masa de 2 kg para poseer una energía

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.
