This question is not about physics science.
The answer is: option <span>a. Five-year-old children have longer attention spans than three-year-old children.
It is the attention ability what let the older children to stay longer in one location instead of being moving between different activities. The younger children who cannot keep their attention long time in a same activity entertain themselves by changing activities.
</span>
a) They collide and stick to one another
b) Inside of the star called Sun. On the earth we don't have such materials that would withstand very high temperatures.
c) As it commonly happens today: boil water, get high-temperature steam, rotate turbine connected to a generator and get electricity
d) Sorry, I don't see any charts.
Answer:
<em>The average speed needed is 68.4 mi/h</em>
Explanation:
<u>Average Speed
</u>
If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:
The distance to get to Denver from the Hamilton Street Campus is d=1,778 miles. An estimated time of t=26 hours should be needed to cover that distance, thus you will need to travel at an average speed of:
V = 68.4 mi/h
The average speed needed is 68.4 mi/h
Sometimes, because acceleration due to gravity on Earth depends on how close you are to the Earth's center.
