<span>Immediate and long lasting because they pollute the water itself which is the most important commodity for humans. Dirty water gives us all types of diseases which are all long lasting and the body has a immediate reaction to the pollutants in the water. Drinking polluted water or even bathing in it can be very harmful to the human body.</span>
Answer:
Explanation:
According to the Fleming's right hand rule, if we spread our right hand such that the thumb, fore finger and the middle finger are mutually perpendicular to each other, then the thumb indicates the direction of force, fore finger indicates the direction of magnetic field, then the middle finger indicates the direction of induced current.
According to the Lenz's law, the direction of induced emf is such that it always opposes the cause due to which it is produced.
Use the equation
The final velocity 
is 68 m/s, the acceleration 
is 8 m/s^2, and the net displacement 
is 33 m, so you can solve for the initial velocity 
:
A^2 + b^2=c^2
that is how to find magnitude
xcos0=20cos180
ycos0=20sin270
that should give you the vectors
and your answer should state the quadrant degree which it is in and vector and direction it is in like west,south
