The range of human hearing is roughly from twenty Hz to twenty kilohertz. Based on these limits and a value of 343 m/s for the speed of sound, what are the lengths of the longest and shortest pipes (open at both ends and producing sound at their fundamental frequencies) that you expect to find in a pipe organ?© BrainMass Inc. brainmass.com October 24, 2018, 5:16 pm ad1c9bdddf
For a pipe open at both ends the frequencies follow the relation
fn=n*v/(2L), where n=1, 2, 3, 4, 5?
where n=1 fundamental freq. and ...
In clear narrative with full calculations, the solution arrives at the answer.
Different perspectives of early psychology
1. Compare and contrast three different perspectives of early psychology.
2. Early behavioral psychologists demonstrated it is easier to modify behavior when the expected behavior is rewarded. For example, you compliment your child for doing well in school, or you get coupons for your next purchase because you spent so much at the grocery store.
1) Explain the benefits of using this type of behavior modification correctly.
2) Also explain some negative affects that can occur if the wrong behaviors are rewarded.
