A trumpet creates a sound wave that has a wave speed of 350m/s and a wavelength of 0.8 m . What is the frequency of the sound wa
1 answer:
Answer:
The frequency of sound wave created by trumpet is 437.5Hz
Explanation:
Given
the speed of sound wave = 350 m
the wavelength of sound wave = 0.8 m
the frequency of sound wave = ?
All the waves have same relationship among wavelength, frequency and speed, which is given by the equation:
v = fλ, where
v is speed of the wave
f is frequency of the wave
λ is wavelength of the wave
therefore frequency of sound wave is given by
f = v/λ
= 350m/0.8m
= 437.5
= 437.5Hz (since 1 = 1 Hz (Hertz)
Hence the frequency of sound wave created by trumpet is 437.5Hz

answer:
1 ) Magnetic field due to long current carrying wire :
Therefore the net magnetic field due the both wires ; B = B + B
. when we adjust the current I
= I
then the Netfield (B ) = zero
2) The distance between the field lines are not equally spaced and this is because the separation between field lines increases with the increase in the distance between the wires
3) Increase in current through the wire will lead to increase in force and this can be explained via this equation

velocity of Prototype
Taking Froude number same for both flow as it is a dimensionless number for different flow regimes in open Flow
The gravitational force between two masses is given by the formula
where G is the <em>gravitational constant, </em>M is the larger mass, m is the smaller mass, and r is the distance between the centers of the objects. The values we can change here to affect that gravitational force are the <em>mass </em>and the <em>distance</em>. Time and shape have no impact on this force.
