I had to look for the options and here is my answer:
Given that a guitar string has a basic frequency of 500hz, the frequency that can be set for this into resonant vibration would be 1500 Hz. The resonant vibration here is necessary in musical instruments because it delivers a vibrating system which leads to a higher amplitude at a particular frequency.
Answer:
same value in R and 2R E = E₀ = σ / 2ε₀
Explanation:
For this exercise we use Gauss's law
Ф = E. dA = 
/ε₀
We define a Gaussian surface with a cylinder with the base being parallel to the load sheet, so the electic field line and the normal line to the base are parallel and the scalar product is reduced to the algebraic product, in the parts the angle is 90º and the dot product is zero
As the sheet has two faces
2E A = q_{int} /ε₀
The charge inside the cylinder is
σ = q_{int} / A
q_{int} = σ A
We substitute
E = σ / 2ε₀
We see that this expression is independent of the distance, so it has the same value in R and 2R
E = E₀ = σ / 2ε₀
Answer:
True.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
A concept is the general idea of objects, events, animals, or people based on common features, traits, or characteristics. It is typically considered to be an abstract idea or general notion that is formed by the mental combination of all the characteristics pertaining to the idea.
Generally, concepts are used in the problem-solving process as it serves as a benchmark or yardstick for the solutions. Some examples of concepts in physics are conservation of energy and momentum, electromagnetic waves, heat, motion and forces, electricity and magnetism, gravity, etc.
During the internal examination, the pathologist drains the intestines, removes any undigested food and feces, and examines the contents of the stomach. This examination could give the pathologist clues of the time of death, and the location of death. The process of digesting and defecation vary from person to person, the entire process is generally considered to take approximately 40 hours in adults
Answer:
- Problem-recognition.
Explanation:
The consumer decision-making process is associated with the process of consumers recognizing their needs and requirements, collecting information followed by the evaluation of distinct alternatives available in the market and then finally reaching a decision to opt for a specific product to buy.
As per the given description, Gilbert's evaluation of his need that his current phone is not able to meet up his requirement and realization that he requires a phone with a longer-battery life exemplifies that he is in the '<u>problem-recognition</u>' phase of the consumer decision-making process. This stage would be followed by the assessment of alternatives(various phones with longer battery life) and reaching the conclusion to buy a specific chosen product after the evaluation.
