A Question 15 (1 point) Retake question Interstellar space, far from any stars, is filled with a very low density of hydrogen atoms (H, not H2). In certain region of space, the number density of hydrogen atoms is 5 atoms / cm . Estimate the number of collisions experienced by the spherical interstellar ship ( diameter 360m) moving at the 40% of the speed of light, in the interstellar space in 1second of its motion. Give your result in quintillions of collisions (1018) to the nearest tenth. (e.g. For a result of 12.34590 x 1018collisions, input 12.3) Take the speed of light c to be 300000km/s. Your
