Water hyacinth can fully cover lakes and wetlands, displacing native aquatic species, reducing fish oxygen levels, and providing optimal habitat for disease-carrying mosquitoes. Water hyacinth infestations can obstruct river transportation, fishing, damage bridges, and clog dams.

2. A stone is thrown vertically upward with a speed of 22m/s.
Eduardwww [97]

Answer:

Explanation:

Energy E is conserved:

E=\frac{1}{2}mv^2+mgh

If v₀ = 22m/s, h₀=0m and h₁=25m:

E=\frac{1}{2}mv_0^2=\frac{1}{2}mv_1^2+mgh_1

Solving for v₁:

v_1=\sqrt{v_0^2-2gh_1}

There is no real solution, because the stone never reaches 25m.

Maureen is training for a backpacking trip. Which of the following training plans follows the FITT
lawyer [7]

Answer:

The answer is "Walk three days a week, gradually adding distance and hills."

Explanation:

The FITT Principle <u>guides a person in becoming a fitter version of himself by following a particular frequency, intensity, time and type of exercise in order to achieve his goals.</u>

<u>Frequency</u>- this refers to how often a person should do an exercise. For example, 5 times a week of intense core workout.

<u>Intensity</u>- this refers to the person's vigour or strength in doing the workout. This depends whether the person is doing a high-intensity or a low-intensity exercise.

<u>Time</u>- this refers to the length of a person's exercise. This will largely depend on every individual's fitness level.

<u>Type of Exercise</u>- this refers to the exercise that a person should incorporate in his training<u> in order to avoid injuries of using the same muscles over and over again.</u>

Among the choices above, it is only the second choice (Walk three days a week, gradually adding distance and hills) that follows the FITT principle. Walking shouldn't be kept at the same pace and distance for many weeks, since it results to<em> boredom and overuse injuries. </em>This will also lead to a plateau when it comes to people who are trying to lose weight because the body has already well-adjusted to the exercise and cannot be challenged anymore.

<em>Gradually increasing the distance and hills will allow the person to be more challenged </em>and<em> </em>will also increase his desire to workout (because he is seeing results).
