Answer:
Part(a) : The required distance is 0.15 m.
Part(b) : Yes it is possible.
Explanation:
Part (a):
We know that, for a string to generate harmonic, it has to vibrate with a frequency () given by
where '' is the velocity of the velocity of the wave, '' is the wavelength of the wave for the harmonic, '' is the length of the string.
In order to produce A4 note (440 Hz), i.e., harmonic on the string, if '' be the required length of the string, then
So, to generate a higher harmonic D5 (587 Hz), i.e., harmonic if we consider '' m be distance from the bridge where the player has to put a finger, then
Part (b):
In order to produce G4 note (392 Hz) which is lower harmonic without retuning, the player has to make such an arrangement that will reduce the vibration of the string which in turn increase the waelength of the wave or decrease the frequency.
Answer:
This is because the air outside is always cooler than the air inside, so after staying outside your body adapts to the cold air, when you come back inside, the cold air is still in you which makes the room seem warmer.
The appropriate response is the last one. A moment normal for transmitters at electrostatic balance is that the electric field upon the surface of the channel is guided altogether opposite to the surface. There can't be a segment of the electric field that is parallel to the surface.
Answer:
The law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products.
