In recent years, astronomers have found planets orbiting nearby stars that are quite different from planets in our solar system. kepler-12b, has a diameter that is 1.7 times that of jupiter (rjupiter = 6.99 × 107 m), but a mass that is only 0.43 that of jupiter (mjupiter = 1.90 × 1027 kg ).

g= 3.86 m/s^2

Explanation:

given : Kepler-12b, has a diameter that is 1.7 times that of Jupiter (R_Jupiter = 6.99 × 10^7 m), but a mass that is only 0.43 that of Jupiter (M_Jupiter = 1.90 × 10^27 kg ).

to calculate gravity we use the formula

g = GM/r^2

g = 6.67×10^-11 × 0.43×1.9×10^27/( 1.7×6.99×10^7)^2

g = 3.859 ~ 3.86 m/s^2

if you answer my question i will answer yours

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
