Answer:
a. Tension of the strings
Explanation:
The koto is a pluckedstring instrument. In these instruments, the sound is obtained causing the vibration in several strings. Therefore, its sound depends on the thickness, extension and tension of the strings. The lower the tension the deeper the sound will be.
Answer:
Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables.
Explanation:
Um... This is not exactly physics...(Although, this school of thought is most likely Moral Relativism.)
Answer:
W=1259W=1.2Kw
Explanation:
Hello!
The first step to solve is to find the enthalpies at the entrance (state 1) and the exit of the washer, for this we use the thermodynamic tables.
Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)
through prior knowledge of two other properties such as pressure and temperature.
state 1
h1(T=20C,P=1atm)=83.93kJ/kg
state 2
h1(T=23C,P=1atm)=96.48kJ/kg
now we find the mass flow remembering that it is the product of the flow rate by the density=
m= mass flow
q=flow=0.1l/S=0.0001M^3/s
α=Density=1000kg/m^3
m=0.1kg/s
Now we draw the energy flows in the washer (see attached image) and propose the first law of thermodynamics that states that the energy that enters must be equal to the one that comes out
where
m=mass flow
h=entalpy
v=speed
W=power input
g=gravity
H=height

W=1259W=1.2Kw
