In 1909, galileo first looked at the milky way using very powerful binoculars
anastassius [24]
<span>Galileo first studied the Milky Way through his telescope in January, 1610 not 1909. Until his observations, the Milky Way was thought to be a band of wispy whitish clouds passing through the heavens. To Galileo's amazement, instead of seeing just a nebula (the Greek work for cloud) the milky wisps resolved into innumerable tiny stars, so crowded together that, without the aid of a telescope, the light from those stars simply blended together. </span>

A race car is one lap behind the lead race car when the lead car has 44 laps to go in a race. If the speed of the lead car is 55
masha68 [24]

Answer:

Speed of second car will be 57.17 m/sec

Explanation:

We have given lead car travels = 44 laps

1 laps = 1.34 km = 1340 m

So total distance = 1340×44 = 58960 m

Speed of lead car = 55.9 m/sec

We know that time=\frac{distance}{speed}=\frac{58960}{55.9}=1054.74sec

As the second car is 1 lap behind so distance traveled by second car = 45×1340 = 60300 m

So speed of second car will be speed=\frac{distance}{time }=\frac{60300}{1054.74}=57.17m/sec
