Answer: A. Sediment
Eutrophication is a phenomena in which a water body gets enriched with minerals and nutrients frequently entered into water body due to run-off from the land, which facilitates dense growth of plants especially on the superficial layers of water body. Decaying organisms, fertilizers and pollution all add nutrients and minerals necessary for plant growth specifically remain floating on the superficial layers of water where plant growth takes place but sediments gets settled at the bottom of the water body, the minerals present in it remain settle at the bottom and hence, does not contribute to eutrophication.
Answer:
Both are aquatic animals and are hunters
Explanation:
Solution :
Mass of the sphere, m = 10 kg
Diameter, D = 300 mm = 0.3 m
Volume of the sphere is 
So the volume of displaced water, 
Additional mass, 
So the total mass, 
= 7.0686 + 10
= 17.0686
Force required, F = Ma
= 170.686 N
<span>A jet of water issuing from a stationary nozzle at 15.3 m/sec (Aj = 0.03 m2) strikes a turning vane mounted on a cart as shown. The vane turns the jet through an angle = 60o. Determine the value of M (in kg) required to hold the cart stationary.</span>
