Answer:
The focal length is 16.86 cm and the distance of the man if he wants to form an upright image of his chin that is twice the chin's actual size is 8.43 cm.
Explanation:
Given that,
Object distance u=1.54 m =154 cm
Image distance v = 15.2 cm
Magnification = 2
We need to calculate the focal length
Using formula of mirror

Put the value into the formula



We need to calculate the focal length
Using formula of magnification

Put the value into the formula


Using formula of for focal length






Hence, The focal length is 16.86 cm and the distance of the man if he wants to form an upright image of his chin that is twice the chin's actual size is 8.43 cm.
The distance between the plates is 7.1 * 10^-7 m
<h3>What is the distance?</h3>
The capacitor is a device that is used to store charges. The capacitor always has a dielectric that is placed between the capacitors that separates them.
Given that;
C = εoA/d
C = capacitance
εo = permittivity of free space
A = cross sectional area
d = distance apart
Cd = εoA
d = εoA/C
d = 8.8 * 10^-12 * 8.89 * 10^-4/1.11 * 10^-8
d = 7.1 * 10^-7 m
