Answer:
Found this off of google, "When you inflate the balloon, the dots slowly move away from each other because the rubber stretches in the space between them. ... This stretching of space, which causes the distance between galaxies to increase, is what astronomers mean by the expansion of the Universe."
Answer:
The required skidded distance would be one-forth of the distance skidded if the velocity of the car becomes half.
Explanation:
If '
' be the velocity of the car where the brakes are slammed on and 'a' be the constant deceleration gained by the car before coming to stop after skidding a distance 'X' at time 't' where final velocity '
', then as can be seen from the figure,
If from any arbitrarily chosen point 'O', '
' be the distance where the brakes are slammed on and '
' be the distance from the same point 'O' where the car stops, then
Now if the car would have been moving with a velocity '
' and would have been skidding a distance 'Y', then from the above equation substituting the velocity we can have
So, if the car were moving at half as fast under the same road conditions, it would have skidded by a distance which is one-forth of the present skidded distance.
The answer is C :), I think.
Answer;
B. Without good stability, athletes are too clumsy to perform well.
Explanation;
Stability refers to the resistance to both linear and angular acceleration, or resistance to disruption of equilibrium.
Developing and enhancing core strength and stability helps athletes to maximize their power output and enhance game day performance. Additionally, Improving core strength and stability can also help athletes reduce their risk of injury.
