Aplanetâs moon revolves around the planet with a period of 39 earth days in an approximately circular orbit of radius of 4.8ã10^8 m. how fast does the moon move?

v = 895 m/s

Explanation:

Time period is given as 39 Earth Days

now the radius of the orbit is given as

so the total path length is given as

now the speed will be given as

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
