Answer:
a) 20.29N
b) 19.43N
c) 15N
Explanation:
To find the magnitude of the resultant vectors you first calculate the components of the vector for the angle in between them, next, you sum the x and y component, and finally, you calculate the magnitude.
In all these calculations you can asume that one of the vectors coincides with the x-axis.
a)
b)
c)
Answer:
A beat with the frequency of 10Hz.
Explanation:
The frequencies from the tuning fork and guitar will cancel each other.
The frequency of tuning fork = 340Hz
The frequency of guitar string= 350Hz
The offset = 350Hz - 340Hz = 10Hz
A 10Hz frequency sound is still heard.
The formula for speed is distance traveled divided by time
Answer: Pressure fluctuations travel along the direction of propagation of the sound wave.
Explanation:
Sound wave is a type of longitudinal wave. It is defined as a wave which consist of vibrations of particles traveling through a medium( such as air, or water).
Sound wave is propagated by the alternating adiabatic compression and expansion of the medium. The COMPRESSIONS are regions of high air pressure while the RAREFACTIONS are regions of low air pressure. Therefore, Since a sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium, it is sometimes referred to as a PRESSURE WAVE.
The direction of the vibrating particles is parallel to the direction of propagation and that's why it's a type of LONGITUDINAL WAVE. Therefore, the correct option that
concludes about the direction in which such pressure fluctuations travel is
(Pressure fluctuations travel along the direction of propagation of the sound wave.)
