What advantages do sports drinks or juices have over water in terms of electrolyte content? Why does this matter for strenuous e
Xelga [282]

Sports drinks do offer some benefits when comparing sports drinks vs. water. While water actually works better at fluid replacement, sports drinks are often more appealing to the palate. In other words, people who enjoy the taste of sports drinks may drink more of a sports drink than they would water; this will lead to better hydration.

Sports drinks also contain electrolytes and carbohydrates. While exercising for short periods of time, it is not necessary to replace electrolytes; however, athletes and marathon participants exercising for period of an hour or more can benefit from electrolyte replacement in particular. Carbohydrates offer the body energy. When the body burns calories, it needs carbohydrates to replace energy lost. The longer the workout, the more carbohydrates are needed.

What is the displacement of an object that starts at the origin and moves to position -8 m?
Alinara [238K]

The displacement is a vector that is calculated by subtracting the final and initial positions of an object that has made a movement.

We know that initially the object was at the origin and moved to the -8m position.

Suppose that the movement was made on the x-axis. So:

d = [-8 - (0)]x

d = -8x

Regarding the second question.

When the acceleration is constant then the speed changes at a constant rate. Therefore the graph of velocity vs. time will look like a line with a negative slope (if the acceleration is negative) or a line with a positive slope (if the acceleration is positive)

For example. Suppose that the acceleration of gravity is 10 m/s^2

Now suppose you drop an object from a building.

At the initial moment (second 0) the speed is 0 m/s.

After 1 second the speed of the object will be 10 m/s.

After 2 seconds the speed of the object will be 20 m/s.

After 4 seconds the speed will be 40 m/s.

The graph of this example is shown in the attached figure. Note that it is a straight line.
