True or false:<br> All of the rivers in the United States are closely monitored For pollution levels
Nutka1998 [239]

All of the rivers in the United States are not monitored closely for pollution levels.

The statement in the question is False

<h3><u>Explanation:</u></h3>

Not all rivers in the United States are closely monitored for their pollution levels. There are volunteers who take responsibility of checking water bodies such as lakes, rivers, streams etc. They take the next step required after finding a water body contaminated.

But to say that all the rivers receive the same amount of attention and action is incorrect. To ensure that all the rivers are clean and pollution free, it would require a lot of man power in the said department which would collect the water samples from all these rivers and send it to labs for checking the pollution level of the particular river. It can be said that the rivers which are situated beside an industrial site, close to a town, will be the priority for checking pollution levels as it would directly cause harm to a small set of population if the toxicity is at an increased level.

A 15.5 kg block is pulled by two forces. The first is 11.8 N at a 53.7 angle and the second is 22.9 at a -15.8 angle. What is th
Ainat [17]

Answer:

1.88 m/s^2 at 6.5^{\circ}

Explanation:

We need to calculate the components of the resultant force on both the x (horizontal) and y (vertical) direction.

Components of the first force F1:

F_{1x} =(11.8) cos (53.7^{\circ})=7.0 N\\F_{1y} = (11.8) sin (53.7^{\circ})=9.5 N

Components of the second force F2:

F_{2x} =(22.9) cos (-15.8^{\circ})=22.0 N\\F_{2y} = (22.9) sin (-15.8^{\circ})=-6.2 N

So the components of the resultant force are

R_x = F_{1x}+F_{2x}=7.0+22.0 = 29.0 N\\R_y = F_{1y}+F_{2y} = 9.5+(-6.2)=3.3 N

So the magnitude of the resultant force is

F=\sqrt{(29.0)^2+(3.3)^2}=29.2 N

And the direction is

\theta = tan^{-1} (\frac{R_y}{R_x})=tan^{-1} (\frac{3.3}{29.0})=6.5^{\circ}

The magnitude of the acceleration can be found by using Newton's second law:

a=\frac{F}{m}=\frac{29.2 N}{15.5 kg}=1.88 m/s^2

while the direction is the same as the resultant force, 6.5^{\circ}.

How did the author describe the claws of uwang and salagubang?​
Anna007 [38]

Answer:

Describes them as sharp and dangerous.

Explanation:

The author describes the claws of uwang and salagubang as large, sharp, dangerous and scary. This creates a certain suspense in the story, as it leaves the reader apprehensive about the imminent danger that these claws pose to those who know them. However, despite their appearance, the claws are not as deadly as they seem because they can only hurt people who are pinched by them.
