m/s

(b) What is its average velocity over a period of one year? (Enter the magnitude.)

a) earths average distance from sun is 1.496 *10^11 m

Time taken by earth to revolve around sun =365 days =365*24*60*60 s=31536000 s

average speed =average distance/time

=1.496*10^11/31536000

=4743.78 m/s

b) average velocity = displacement / time.
Over a period of one year, the displacement is zero, therefore the average velocity is 0

Tha (a) was wrong

see it depends on what radius you choose for earths revolution

do you have value for radius?  or earths distance from sun???

Sry,I`m not have

okay put and see 29.87 m/s
