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
The answer is A because you have to have erosion
Answer:
Yes
Explanation:
Accerelation is measured by change in velocity. So naturally, if an object is slowing down, its velocity is decreasing so acceleration is negative. If it is speeding up velocity is increasing so positive acceleration.
(Velocity final - Velocity initial)/t
Note that this does not apply only to gravity, but to all linear accelerations
Answer:
The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
