It’s decreasing as environmental cause osmosis
Answer: A. Hydrogen has a valence of 1 and Oxygen has a valence of 8.
Explanation:
Meaning that oxygen has 8 valence electrons in its outer shell and hydrogen has 1 valence electron in its outer shell
If the spring constant of the bungee rope is greater than that of a rubber band, it will have more elastic potential energy. However, if the spring constant of the rubber band is greater than that of the bungee rope, the rubber band will have more elastic potential energy.
<h3>Elastic Potential energy </h3>
Elastic Potential energy is the stored in a elastic string which has been compressed or stretched.
The formula for calculating elastic potential energy is given as:
- Elastic Potential = 1/2 Kx^2
where
- K is the spring constant of elastic material
- x is the distance if compression or stretch
The elastic potential of an elastic material depends on the spring constant and the distance stretched or compressed.
Since the bungee rope and the rubber band are stretched the same distance, their elastic potential energy depends on their spring constant.
Therefore, if spring constant of the bungee rope is greater than that of a rubber band, it will have more elastic potential energy. However, if the spring constant of the rubber band is greater than that of the bungee rope, the rubber band will have more elastic potential energy.

The so-called "velocity-time" graph is actually a "speed-time" graph. At any point
on it, the 'x'-coordinate is a time, and the 'y'-coordinate is the speed at that time.
'Velocity' is a speed AND a direction. Without a direction, you do not have a velocity,
and these graphs never show the direction of the motion. It seems to me that it would be
pretty tough to draw a graph that shows the direction of motion at every instant of time,
so my take is that you'll never see a true "velocity-time" graph.
At best, it would need a second line on it, whose 'y'-coordinate referred to a second
axis, calibrated in angle and representing the 'bearing' or 'heading' of the motion at
each instant. The graph of uniform circular motion, for example, would have a straight
horizontal line for speed, and a 'sawtooth' wave for direction.
