An artificial satellite is moving in a circular orbit of radius 42250 km. Calculate its speed if it takes 24 hours to revolve around the earth

Distance covered by the satellite in 24 hours

s=2πr

  =2×3.14×42250=265464.58 km

Therefore speed of satellite,

v  =

 =  24×60×60 /265464.58  

 =  −

Explanation:

v=  time taken /distance travelled

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

volts times amps 6 x 0.5 3w
