Students in ms. bailey's class were studying speed. four students rolled balls across the floor a distance of 30 cm. their times are seen here. put the times in order from fastest to slowest. a) ball 1 - ball 2 - ball 3 - ball 4 b) ball 1 - ball 2 - ball 4 - ball 3 c) ball 2 - ball 1 - ball 4 - ball 3 d) ball 4 - ball 3 - ball 2 - ball 1

i'm so sorry if this is wrong i'm only in 6th grade xd

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

hope this ! this is not copied! search it up, it's free of plagiarism!

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
