Answer:
Explanation:
given,
speed of wind, = 14 m/s
frequency of horn,f_s = 1000 Hz
speed of sound,V = 344 m/s
frequency heard by the listener
using Doppler effect
f_L is the frequency of the sound heard by the listener
f_s is the frequency of sound emitted by the listener
V is the speed of sound
v_L is the speed of listener
v_s is the speed of source
now,
considering the frame of reference in which wind is at rest now, both listener and the source will be moving at 14 m/s
now on solving we will get
hence, the frequency heard by the listener is equal to 1000 Hz
Answer:
Explanation:
Laminar Flow is a very important topic discussed in physics in the subject of fluid dynamics. Basically, it explains how fluid particles behave at lower velocities. In such cases and when the viscosity of the fluid is low, the fluid particles flow smoothly in perfectly perpendicular layers that do not collide or cross each other. Unlike turbulent flow, which is the opposite. An example of Laminar flow can be seen when you open up a water hose with little pressure, the water simply flows out of the hose and looks very clear and smooth.
Explanation:
a) P = IV
2000 W = I (230 V)
I = 8.7 A
b) The fuse must be rated for a higher current than the kettle, so use the 13A fuse.
c) Double insulation means there are two layers of insulation, insuring that the wires cannot touch the outer casing of the kettle and protecting the user from electrical shock.
d) V = IR
230 V = (8.7 A) R
R = 26.5 Ω

Given what we know, the statement in this question can be considered as true, since Syncopation does in fact shift the beat off of regular rhythms.
<h3>What is Syncopation?</h3>
- This is when regular beats are offset in order to disrupt the melody.
- This is done purposefully.
- It causes the listener a need to continue in order to hear the beat return to normal.
Therefore, given that Syncopation is defined as a shift or displacement in the rhythms or beats from something <em><u>strong and normal</u></em> to something that causes the listener to want the beat to go back to normal.
