Explanation:
Orbital speed
Here,
g_"at moon's distance"=(6.7*10^-11*5.97219 * 10^24)/( 3.85 × 10^8)^2
=0.00270795635color(white)(i)ms^-2 Orbital radius of Moon
= 385,000 color(white)(i)km = 3.85 × 10^8 m

Explanation:
Here,
"Distance of Moon from Earth (avg.)"=384,400" km"
=384,400xx1000" m" "Distance travelled by Moon"="Circumference"
=2pir=color(red)(2xxpixx384,400xx1000 " m" "Time taken to complete one orbit"=27.32" days"
color(blue)(=27.32xx24xx60xx60" s"
