Answer:
Active listening is a technique that is used in counseling, training, and solving disputes or conflicts. It requires that the listener fully concentrate, understand, respond and then remember what is being said. This is opposed to other listening techniques like reflective listening and empathic listening.
Explanation:
Answer:
1) The block of wood is at rest.
2) Weight and Normal Reaction (see attached diagram).
Explanation:
<u>Assumptions</u>
- The block of wood is a particle (a body whose mass acts at a point, so its dimensions don't matter).
- There are no other external forces involved.
<u>Question 1</u>
"At rest" or "resting" means that the <u>object isn't moving</u>.
Therefore, the block of wood is at rest.
<u>Question 2</u>
Forces that are acting on the block of wood:
- <u>Weight (W)</u>: Due to the particle's mass, m, and the acceleration due to gravity, g: W = mg
(Weight always acts downwards).
- <u>Normal Reaction (R or N)</u>: The reaction from a surface.
(Normal Reaction is always at 90° to the surface).
See attached diagram.
Answer:
A. Using artificial fertilizers instead of composting
Explanation:
Composting is actually more better than fertilizers usually, as it takes natural waste and with help of nature, returning the nutrients into soil once again. However, Artificial fertilizers usually uses chemicals to ensure that weed does not grow, and may contain other "unnatural" ingredients to ensure that only the crop grows on the field. Because of the usage of non-natural ingredients, any run-off can prove to be detrimental to any animals that eat any of the run-off infected material, or drink the polluted water.

Answer:
<em>The pressure given by the water at the bottom is 58,800 Pa</em>
Explanation:
<u>Pressure Exerted by a Column of Liquid
</u>
The pressure P exerted by a column of liquid of height h and density ρ is given by the hydrostatic pressure equation:
P = ρgh
Where ρ is the density of the liquid, g is the acceleration of gravity g=9.8m/s^2, and h is the height of the column of liquid.
The height of water in a well is h=6 m. The density of water is a known quantity:
Calculating P:
P = 1,000*9.8*6
P = 58,800 Pa
The pressure given by the water at the bottom is 58,800 Pa
