The maximum distance from the earth to the sun (at aphelion) is 1.521 1011 m, and the distance of closest approach (at perihelion) is 1.471 1011 m. the earth's orbital speed at perihelion is 3.027 104 m/s. ignore the effect of the moon and other planets. (a) determine the earth's orbital speed at aphelion. m/s (b) determine the kinetic and potential energies of the earth–sun system at perihelion. kp = j up = j (c) determine the kinetic and potential energies at aphelion. ka = j ua = j (d)is the total energy constant

29274.93096 m/s

Explanation:

= Distance at perihelion =

= Distance at aphelion =

= Velocity at perihelion =

= Velocity at aphelion

m = Mass of the Earth =  5.98 × 10²⁴ kg

M = Mass of Sun =

Here, the angular momentum is conserved

Earth's orbital speed at aphelion is 29274.93096 m/s

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

we need to know the time interval during which the force acts. impulse of force = momentum change
