In june 1997 the near spacecraft, on its way to photograph the asteroid eros, passed near the asteroid mathilde. from photos transmitted by the spacecraft, mathilde's size was known. it is presumably made of rock. rocks on earth have a density of about 3000 kg/m3 (3 grams/cm2). from the observations of the motion of the spacecraft as it passed mathilde, scientists were able to learn something surprising about the asteroid in this problem you will analyze a similar situation. a spacecraft with mass 900 kg was traveling at nearly constant velocity with speed 9000 m/s. it flew past an asteroid, and the distance of closest approach (d in the diagram) was 3700 km (3.7e6 m). from photos taken by the spacecraft, it was determined that the asteroid had roughly the shape of a box 40 km by 60 km by 20 km (4e4 m by 6e4 m by 2e4 m)

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
