Answer:
Part a)
![\tau = 23.1 Nm](https://tex.z-dn.net/?f=%5Ctau%20%3D%2023.1%20Nm)
Part b)
![\tau = 17.05 Foot pound force](https://tex.z-dn.net/?f=%5Ctau%20%3D%2017.05%20Foot%20pound%20force)
Explanation:
As we know that torque is defined as the product of force and its perpendicular distance from reference point
so here we have
![\tau = \vec r \times \vec F](https://tex.z-dn.net/?f=%5Ctau%20%3D%20%5Cvec%20r%20%5Ctimes%20%5Cvec%20F)
now we have
![\tau = (0.140)(165)](https://tex.z-dn.net/?f=%5Ctau%20%3D%20%280.140%29%28165%29)
![\tau = 23.1 Nm](https://tex.z-dn.net/?f=%5Ctau%20%3D%2023.1%20Nm)
Part b)
Now we know the conversion as
1 meter = 3.28 foot
1 N = 0.225 Lb force
now we have
![\tau = 23.1 Nm](https://tex.z-dn.net/?f=%5Ctau%20%3D%2023.1%20Nm)
![\tau = 23.1 (0.225 Lb)(3.28 foot)](https://tex.z-dn.net/?f=%5Ctau%20%3D%2023.1%20%280.225%20Lb%29%283.28%20foot%29)
![\tau = 17.05 Foot pound force](https://tex.z-dn.net/?f=%5Ctau%20%3D%2017.05%20Foot%20pound%20force)
Explanation:
The equation of grating is given by :
![(a+b)\ sin\theta=n\lambda](https://tex.z-dn.net/?f=%28a%2Bb%29%5C%20sin%5Ctheta%3Dn%5Clambda)
Here,
(a+b) is called grating element
N is the number of slits per unit length, ![N=\dfrac{1}{(a+b)}](https://tex.z-dn.net/?f=N%3D%5Cdfrac%7B1%7D%7B%28a%2Bb%29%7D)
n is the order
is the wavelength of light used
is the diffraction angle
Here, we need to write the effect on the interference pattern produced by a grating if the number of slits per unit length is increased. If the number of slits per unit length increases, the grating element decreases such that the angle of diffraction increases. Hence, the interference pattern shrinks.
Answer:
lol do you still need help?
Explanation:
A motor turns electrical energy into mechanical energy.
A generator does exactly the opposite.
