Answer 1

(a) Concave mirror - as it can produce real image and thus it can be captured on screen.

(b) Linear Magnification/Magnification of mirror = -v/u
Given:
v = 60 cm
u = -15 cm
Linear Magnification/Magnification of mirror = -(60)/(-15)
                                                                          = 4

(c) Distance between the object and its image = Distance of object from the
                                                             mirror + Distance of image from the mirror
                                                                              = 60 + 15
                                                                              = 75 cm


:) Hope this Helps !!!
