The answer would be: c. High levels of dissolved oxygen
Oxygen is vital for most (aerobic) organism. Fish using oxygen that dissolved in the water so high level of dissolved oxygen will make the fish grow easier. Water with pH of 5 would be an acid water. Acid is corrosive and it can kill some organism that sensitive. High levels of fecal coliform mean the water contaminated with fecal material and must have a high level of bacteria.
Answer:
True
Explanation:
an object in motion stays in motion unless acted upon by another force
kinetic <span>energy when the pitcher has thrown it or when one of the other players has thrown the ball. The baseball also has </span>kinetic<span> energy when the batter hits the ball. when you catch the ball it is potential energy.</span>
The work done is calculated by multiplying the Force by the distance. So, 10x20 = 200 joules.
Answer:
His average speed.
Explanation:
Average speed = Total distance travelled / total time .
In the given case odometer measures total distance travelled . Dividing it by time will give average speed .
Average velocity can not be the answer as it is measured by dividing displacement by time . Displacement here is zero because initial and final point are same . Instantaneous velocity is given by the speedometer . It keeps on changing all the time . It is actually speed at a particular point of time . It can not be average velocity or speed .
