Answer:
0.130
Explanation:
From the given data, the coefficient of static friction for each trial are:
1. 0.053
2. 0.081
3. 0.118
4. 0.149
5. 0.180
6. 0.198
The sum of the coefficient of static friction = 0.053 + 0.081 + 0.118 + 0.149 + 0.180 + 0.198
= 0.779
So that;
the average coefficient of static friction =
=
= 0.12983
The average coefficient of static friction is 0.130
Explanation:
It is given that,
The distance between the first spot and the central minimum is, s = 0.007 cm
Length, l = 12 m
Wavelength,
We need to find the width of the hair. Using the condition of diffraction pattern as :
, d is the width of the hair
d = 0.00102
or
So, the width of the hair is . Hence, this is the required solution.
