Answer:
Explanation:
For this case we can use the second law of Newton given by:
The friction force on this case is defined as :
Where N represent the normal force, the kinetic friction coeffient and a the acceleration.
For this case we can assume that the only force is the friction force and we have:
Replacing the friction force we got:
We can cancel the mass and we have:
And now we can use the following kinematic formula in order to find the distance travelled:
Assuming the final velocity is 0 we can find the distance like this:
Answer:
0.0000167283525619 N
Explanation:
= Density of silk = 1300 kg/m³
d = Diameter = 0.002 mm
r = Radius = 0.001 mm
l = Length = 16 cm
f = Frequency = 200 Hz
Mass of the string is
Frequency is given by
The tension on the string is 0.0000167283525619 N
