Each of these instruments have a very wide range of notes because these are all treble instruments. Now, if you mean altogether, with a trumpet you can hit a very wide range of notes due to it having such a high octave, same with a violin, piano, clarinet, and organ. Kettle drums just have a very manipulable sound.
But remember it is a MIDI System, and you can adjust the frequency according to your desire; So, honestly, there is no straight answer for this, just how you desire the sound.
I could take an A4 note on a trumpet and stretch the sound waves out to sound like an A1 note just by bending it with a MIDI System. So, the possibilities are endless.<span />
Answer:
0.125Hz
Explanation:
The relationship between period and frequency is given by
where f is the period and T is the frequency.
Given that T = 8.00s
The period of a swinging object is the time it takes to make one complete oscillation, it is measured in seconds (s) while the frequency is the number of complete oscillations made per unit time and it is measured in Hertz (Hz). Period and frequency are inverse of each other.
Answer:
Explanation:
Total heat gain by the block ΔQ = 2 x 12 kJ = 24 kJ .
Gain of potential energy = mgh = 12 x 9.8 x 32 = 3.763 kJ
Decrease in kinetic energy KE = 1/2 x 12 ( 40² - 7² )
= 9.306 kJ
increase in internal energy ΔE = 70 kJ
ΔQ = ΔE + PE - KE + W , W is work done by the gas
Putting the values
24 = 70 + 3.763 - 9.306 + W
W = - 40.457 kJ .
Since W is negative that means work is done on the system .
Answer:
1.45
Explanation:
Refractive index of the liquid is given as;
Refractive index =
But,
speed =
Since a certain light of specific wavelength was used during the same time, let the time be represented by t.
So that;
speed of light in vacuum =
speed of light in the liquid =
Refractive index = ÷
= x
Refractive index =
= 1.4536
= 1.45
The refractive index of the liquid is 1.45.
