The average distance between the earth and moon is 3.84x10^5km how far is this in miles

The time that would  take   a radio wave with the frequency of 7.25 x 10^5 Hz  to travel from  earth to the moon is    1.28  sec

Explanation:

Time =  distance / speed

distance =  3.84 x 10 ^5 km

convert  Km to m

1 Km= 1000 m

3.84 x10^5km= ? m

by cross multiplication

= (3.84 x 10^5 km x 1000 m) / 1 km = 3.84 x 10 ^8 m

Speed  of light=  3.0  x 10^8 m/s

therefore time =  3.84  x10^8 m / 3.0  x10^8 m/s =  1.28  sec

answer: a ball

explanation: because it will bounce

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
