Answer:
(a) convex mirror
(b) virtual and magnified
(c) 23.3 cm 
Explanation:
The having mirror is convex mirror. 
distance of object, u = - 20 cm
magnification, m = 1.4 
(a) As the image is magnified and virtual , so the mirror is convex in nature. 
(b) The image is virtual and magnified. 
(c) Let the distance of image is v. 
Use the formula of magnification. 

Use the mirror equation, let the focal length is f. 

Radius of curvature, R = 2 f = 2 x 11.67 = 23.3 cm

Emf = d (phi-B) / dt 
<span>B dA/dt, where dA/dt is the area swept out by the wire per unit time. </span>
<span>0.88 V = (0.075 N/(A m)) (L)(4.20 m/s), so </span>
<span>L = (0.88 J/C) / [ (0.075 N s/C m)(4.2 m/s) ] = about 3 meters</span>
        
                    
             
        
        
        
Elements of art are stylistic features that are included within an art piece to help the artist communicate. The seven most common elements include line, shape, texture, form, space, colour and value, with the additions of mark making, and materiality.
You would create a darker value if you shaded it, shading it makes it darker.
