Answer:
1.85 m
Explanation:
The horizontal velocity of the ball is
The horizontal distance travelled is
d = 2.7 m
And since the motion along the horizontal direction is a uniform motion, the time taken is
The vertical position of the ball is given by
where
h = 1 m is the initial heigth
is the initial vertical velocity
g = 9.82 m/s^2 is the acceleration due to gravity
Substituting t = 0.53 s, we find the height of the ball at this time:
W=gPE the work done on the bucket is equal to the gravitational PE so PE=100j
Imagine that the two atoms are playing tug of war with the electron, but one is pulling with a stronger force than the other. This inequality results in the majority of the rope being pulled toward the stronger atom. In the bond, the electron is pulled closer to the stronger atom too. This results in each side having a partial charge, one being more negative than the other.
The best answer is b) increased turbidity from erosion.
Nonpoint source pollution generally happens as a result of many systems interacting, and is not directly attributed to one event or pollutant. Generally, natural environmental systems participate in pollution of this kind, regardless of whether or not human activity was a factor. Examples include water runoff, or erosion.
The other pollutants listed have a direct cause and direct effect, the animal waste goes directly from the animals to the ground they live on, the car shop directly sumps the oil on the ground, and the oil tank leaks directly into the earth. Erosion causing turbidity is a less direct form of pollution, and is due to the synthesis of several natural phenomena<span />
