Stimulus discrimination happens if two stimuli are adequately particular from each other that one inspires a molded reaction yet alternate does not. It also gives the capacity to separate between stimuli. For instance, your dog comes running into the kitchen when she hears the sound of the electric can opener, which she has learned is utilized to open her canine sustenance when her supper is going to be served. She doesn't bound into the kitchen at the sound of the nourishment processor, despite the fact that it sounds comparable. As it were, she separates between the stimuli.
Answer:
B. electricity
Explanation:
The concept of Electricity already been discovered in 1752. The technologies for mass production started to emerged during industrial revolution in 1760. At that time, most of them use coal as source of energy rather than Electricity.
<u>- Cotton gin</u>
This invention allowed mass production of cotton for the textile industry.
<u>- The production Line</u>
Initially, this invention was made to mass produce vehicles.
<u>- Bessemer Steel process</u>
This invention was made to mass produce steel from molten pig iron
Answer:
0.05 m from the top end
Explanation:
Data provided in the question:
Length of the violin string, λ₁ = 0.45 m
Frequency, f₁ = 392 Hz
New frequency of the violin note, f₂ = 440 Hz
Now,
The velocity of the wave in the string remains constant constant if tension remains constant.
Also,
velocity, v = fλ
thus,
f₁λ₁ = f₂λ₂
392 × 0.45 = 440 × λ₂
or
λ₂ = 0.40 m
thus,
The finger should be placed at (0.45 - 0.40 ) = 0.05 m from the top end
The correct answer to this open question is the following.
Although the question does not provide any options, we can say that the ethical standard that waiting to propose the study violates is "Informed Consent to Research."
In this case, Professor Hammond, first, had to inform the students about the study she was doing so the students were aware of this situation is class. So once she notified the class about her research, then ask them their consent to participate in the study. They probably had to sign a document that serves as an agreement of their participation. The students then would be aware of the details of the research and they would decide if they want to be part of the study. That is the ethical way to proceed.
