The operation of a motor depends on the relationship between electric and magnetic forces. hoped this helped
Answer:
176.9N
Explanation:
The following data were given
wire length,L=37cm=0.37m
linear density=18g/m
tube length,=192cm=1.92m,
speed of sound,v=343m/s
Since it is an open-closed tube, the second harmonic frequency is expressed as
The relationship between the tension, linear density and second harmonic frequency is expressed as
For the potential energy is converted to kinetic energy is mathematically given as
n=24.44%
<h3>What efficiency of the potential energy is converted to kinetic energy?</h3>
Generally, the equation for the potential energy is mathematically given as
Ei=mgh
Ei=49.0\*9.81* 1.8
Ei=865.24J
Final total energy
K.E=0.5mv^2
K.E=0.5*49.0* (3.00)^2
K.E=211.5J
In conclusion, efficiency
n=Ef/Ei*100
n=211.5*865.24*100
n=24.44%
