<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>
The force of attraction between two objects is proportional to the mass of the objects and inversely proportional to the square of teh distance between them. In this casem if the distance is decreased to 1/10 of the original, then teh force of attraction increases by 100 times (10^2).
<h2>The work done = - 2 x 10⁴ J</h2>
Explanation:
In the first case , the volume is kept constant and pressure varies .
In isothermal process , the work done
W₁ = V x ΔP
here V is the volume of gas and ΔP is the change in pressure
Thus W₁ = 0
Because there is no change in volume , therefore displacement is zero .
In second case pressure is constant , but volume changes
Thus W₂ = P x ΔV
here P is the pressure and ΔV is the change in volume
Therefore W₂ = 4 x 10⁵ x 5 x 10⁻² = 2 x 10⁴ J
The total work done W = - 2 x 10⁴ J
Because the work done in compression is negative .
Answer:
Time=15,Mass=3,Acceleration due to gravity=10,Height=50,Power=?.
Power=mgh/t.....which is 3×10×50=1500/15=100Watts.
