HELP PLEASE ITS MY H/W 15. Describe the relationship between Distance from the Sun and Orbital Velocity? 16. Describe the relationship between Distance from the Sun and Period of Revolution? 17. Can you explain why this is the case? (Think about the force of gravity before you answer) YOU WILL GET 25 POINTS PLS HELP.

relationship between a planet's distance from the Sun and its period of revolution. ... The further away from the Sun it is, the slower the planet's orbital speed and the longer its path. Both of those factors result in taking longer to make one complete orbit and a planet having a longer year.

16. Kepler's third law of planetary motion says that the square of the planet's orbital period is proportional to the cube of its semimajor axis. That is, a planet's 'year' is determined only by its average distance from the Sun.

Sorry i know only this much

But still hope this helps you

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

c) up is the direction the magnetic force is acting on the charge.
