Explanation:
Excess fertilizer use results in nutrient pollution by effecting the nutrition values of the plants we eat.
Cutting down trees more likely to result in air pollution by an increase in greenhouse gases.
Pouring oil in drain creates water pollution which is not a nutrient source.
Answer:
GPS Satellites.
Explanation:
You will always be able to have access to 4 of them no matter where you are on the Earth. This is useful for triangulation.
Answer: 0 m
Explanation:
Let's begin by stating clear that movement is the change of position of a body at a certain time. So, during this movement, the body will have a trajectory and a displacement, being both different:
The trajectory is the <u>path followed by the body</u> (is a scalar quantity).
The displacement is <u>the distance in a straight line between the initial and final position</u> (is a vector quantity).
According to this, in the description Matthew's home is placed at 0 on a number line, then he moves 10 m to the park (this is the distance between the park and Mattew's home), then 15 m to the movie theatre until he finally comes back to his home (position 0). So, in this case we are talking about the <u>path followed by Matthew</u>, hence <u>his trajectory</u>.
However, if we talk about Matthew's displacement, we have to draw a straight line between Matthew's initial position (point 0) to his final position (also point 0).
Now, being this an unidimensional problem, the displacement vector for Matthew is 0 meters.
Answer:
8.436 Nm
16.872 Nm
0
Explanation:
When we multiply the force with the distance at which the force is being applied we get torque
where
F = Force = 111 N
r = Distance = 0.152 m
= Angle at which force is applied
When,
The torque is 8.436 Nm
When,
The torque is 16.872 Nm
When,
The torque is 0
