Answer:
We answer that before but I forgot
Magnitude of acceleration
Explanation:
We know that acceleration can increase depending in the force applied on an object, any object with a greater mass will apply a greater force. F = M(a).
<span>Having high standards and honesty in the behavior is called a virtue and the person is considered virtuous. Usually virtue is mean between two extremes as that mid ground gives a balance to the behavior. Virtues are means between the extremes of vices which are excess and deficiency.</span>
Explanation:
It is given that,
Radius of curvature of the mirror, R = 1.54 cm
(a) We have to find the focal length of the mirror. The relationship between the focal length and the radius of curvature is given by :

f = focal length of the mirror

f = 0.77 cm
(b) The power of mirror is given by the reciprocal of focal length i.e.
Power, 
P = 1.29 diopters
Hence, this is the required solution.
