The wavelength of sound wave with frequency 770 Hz and speed of 290 m/s is equal to 0.3767 m
<h3>
Explanation:</h3>
The wave equation determining the relationship between speed, frequency and wavelength of a sound wave is given by:
<u>Speed of sound = Frequency of sound × Wavelength of sound wave</u>
v = n × λ .................................(1)
Given:
v = Speed of sound wave = 290 m/s
n = Frequency of sound = 770 Hz
λ = Wavelength = ?
From (1)
v = n × λ
Rewriting the equation for λ, we get
λ = 
Substituting the values of v and n, we get
λ = 
Hence, the wavelength of sound wave is equal to 0.3767 m
Answer:
For A
Displacement= 1/2*3*6= 9m
For B
Displacement= 1/2*4*4= 8m
Jurgen Habermas is a German philosopher and sociologist
which is an expert in the field of critical conjecture and pragmatism. He is most
widely known for his theories regarding communicative rationality and the
public sphere. This concept of intersubjectivity is called as:
“Intersubjectivity
of mutual understanding”
Answer:
Energy May be measured in joule
Answer: Option (B) is the correct answer.
Explanation:
It is advised that while conducting an experiment in a laboratory, always perform it under the supervision of your teacher.
When Hiro accidentally touches the liquid then he should immediately tell his teacher about it so that timely precaution can be taken to avoid any damage or side effect. Also, Hiro should rinse his hand in the sink because it will neutralize or decrease the effect of spilled liquid on his skin.
Thus, we can conclude that he should tell his teacher about the spill and rinse his hand in the sink.
