Answer:
The power of the mirror is -17.24 diopter.
Explanation:
Magnification of an image,m =
Distance of the object from the mirror = u = 29.0 cm
Distance of an image from the mirror = v
Magnification =
Focal length of mirror = -5.8 cm =-0.058 m
Power of the lens = P
Answer:
Magnetic dipole moment is 0.0683 J/T.
Explanation:
It is given that,
Length of the rod, l = 7.3 cm = 0.073 m
Diameter of the cylinder, d = 1.5 cm = 0.015 m
Magnetization,
The dipole moment per unit volume is called the magnetization of a magnet. Mathematically, it is given by :
Where
r is the radius of rod, r = 0.0075 m
So, its magnetic dipole moment is 0.0683 J/T. Hence, this is the required solution.
