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
combustion of fossil fuels would be the correct answer when dealing with the alteration of the carbon cycle.
Answer:
(A)
(B) s = 146.664 m
Explanation:
We have given car starts from the rest so initial velocity u = 0 m /sec
Final velocity v = 88 km/hr
We know that 1 km = 1000 m
And 1 hour = 3600 sec
So
Time is given t = 12 sec
(A) From first equation of motion v = u+at
So
So acceleration of the car will be
(b) From third equation of motion
So
s = 146.664 m
Distance traveled by the car in this interval will be 146.664 m
I think the answer is option 2
