The relations between gravity masses and spherical radius are obtained. The results indicate that no matter what the masses and densities of hollow sphere and solid sphere are, space-time with radius r0 and constant density ρ0 , inner pressure intensity p(r) is related to coordinate but does.Answer with step by step detailed solutions to question from HashLearn's Physics, Motion of System of Particles and Rigid Body- "A solid sphere of mass Mand radius R rolls on a horizontal surface without slipping, the ratio of rotational K.E. to total K.E. is" plus 3447 more questions from Physics.

76. A sphere of radius r just fits into a cylindrical container of radius r and altitude 2r. Find the empty space in the cylinder. 97. The base of a certain solid is a triangle of base b and altitude h. if all sections perpendicular to the altitude of the triangle are regular hexagons, find the volume of the solid.1.264. A uniform solid cylinder of radius R = 15 cm rolls over a horizontal plane passing into an inclined plane forming an angle α = 30° with the 1.286. A uniform sphere of mass m = 5.0 kg and radius R = 6.0 cm rotates with an angular velocity ω = 1250 rad/s about a horizontal axle passing...
