Having and drinking hygienic
water is human right and is vital to life. The water should be tested, treated
and filtered to remove any contaminants that can lead do sickness. Some of the
strategies in which local municipality is implementing in <span>addressing the topic of lack of clean water are:
1. </span><span>Good monitoring of the water supplies
2. Desalination – </span>this is removal of mineral components from saline water
especially salt. The procedure is more expensive but is a way to reuse water <span>
<span>3. Campaign for more proficient and more wisely usage of the
water in order to make the people conscious of the fact how important the
natural resource water is.</span></span>
<span>Displacement is identified as the net movement of a thing with detail to its initial location. One may journey out of his city and come back. Notwithstanding having enclosed many miles, he will have a displacement of 0. This is true for all trails that have zero displacement that they all go back to their initial position.</span>
Answer:
Maximum Height
Explanation:
The maximum height is the highest point reached by a projected body. At this point, final velocity, v of the body is equal to 0; because upward motion is at its peak and the body start to fall again.
Hence, final velocity v is always 0 at this maximum point and the direction of motion changes from upward to downward.
Final velocity at this maximum height is zero because of the directional change experied by the object and the fact that upward motion of the body terminates at this point.
Answer:
285 seconds
Explanation:
Jenny speed is 3.8 m/s
Alyssa speed in 4.0 m/s
Alyssa starts after 15 seconds
Find the distance covered by Jenny, when Alyssa starts
Distance=Speed*time
Distance covered by Jenny in 15 seconds= 3.8×15=57m
Relative speed of the two members heading same direction will be;
4.0m/s-3.8m/s=0.2m/s
To find the time Alyssa catch up with Jenny you divide the distance to be covered by Alyssa by the relative speed of the two
Distance=57m, relative speed=0.2m/s t=57/0.2 =285 seconds
=4.75 minutes
PE is the energy acquired by a body due to its height ! While KE is the energy acquired by the body due to its motion !
KE+PE = mechanical energy and thus mechanical energy is always conserved due to the conservation of energy which states that energy is neither created nor destroyed but only transformed !
