Explanation:
Sky appears blue because of Scattering.Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Answer:
Acceleration = Force/Mass
Explanation:
Hey there! <span>The cohesive forces between liquid molecules are responsible for the phenomenon known as </span>surface tension<span>. The molecules at the </span>surface do<span> not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the </span>surface<span>. Hope this helps! :)</span>
Firstly let us get the time down to minutes from hours. Then the calculation will become easy.
1 hour and 45 minutes = (60 + 45) minutes
= 105 minutes
So
The distance traveled by the car in 105 minutes = 98 miles
Then
The distance traveled by the car in 60 minutes = (98/105) * 60 miles
= 5880/105 miles
= 56 miles
So the average speed of the car as can be seen from the above deduction is 56 miles per hour.
