Answer:
Because the different waves will feel like to bounce off to different directions, and different items will do different actions.
The answer for the following problem is mentioned below.
The option for the question is "A" approximately.
- <u><em>Therefore the elastic potential energy of the string is 20 J.</em></u>
Explanation:
Given:
Spring constant (k) = 240 N/m
amount of the compression (x) = 0.40 m
To calculate:
Elastic potential energy (E)
We know;
<em>According to the formula;</em>
E = × k × x × x
<u>E = </u><u> × k ×(x)²</u>
where;
E represents the elastic potential energy
K represents the spring constant
x represents amount of the compression in the string
So therefore,
Substituting the values in the above formula;
E = × 240 × (0.40)²
E = × 240 × 0.16
E = × 38.4
E = 19.2 J or approximately 20 J
<u><em>Therefore the elastic potential energy of the string is 20 J.</em></u>
Answer:
e. All of the above would require an EPA permit
Explanation:
For a company to discharge their by-products or waste such as wastewater, the company will need to obtain a specific permit for the Environmental Protection Agency (EPA). The EPA was formed to ensure that the integrity of the environment is not compromised. Thus, all of the options in the given question requires an EPA permit.
Answer:
true
Explanation:
ionic compounds do not form molecules
inertia - Tightening of seat belts in a car when it stops quickly
force - pushing a door
speed - driving your car from home to work at a constant speed of 30Km/Hr
